AP2181D/AP2191D Application Note The AP2181D and AP2191D are integrated high-side power switches optimized for Universal Serial Bus (USB) that require protection functions. The power switches are equipped with a driver that controls the gate voltage and incorporates slew-rate limitation. This, along with the various protection features and special functions, make these power switches ideal for hot-swap or hot-plug applications. Protection Features: Undervoltage Lockout (UVLO) Under-voltage lockout function (UVLO) guarantees that the internal power switch is initially off during start-up. The UVLO functions only when the switch is enabled. Even if the switch is enabled, the switch is not turned ON until the power supply has reached at least 1.9V. Whenever the input voltage falls below approximately 1.9V, the power switch is turned off. This facilitates the design of hot-insertion systems where it is not possible to turn off the power switch before input power is removed. Overcurrent and Short Circuit Protection An internal sensing FET is employed to check for overcurrent conditions. Unlike current-sense resistors, sense FETs do not increase the series resistance of the current path. When an overcurrent condition is detected, the device maintains a constant output current and reduces the output voltage accordingly. Complete shutdown occurs only if the fault stays long enough to activate thermal limiting. The different overload conditions and the corresponding response of the AP2181D/AP2191D are outlined below: S. NO Conditions Explanation Behavior of the AP2181D/AP2191D Output is shorted before The IC senses the short circuit and immediately clamps 1 Short circuit condition at start-up input voltage is applied or before the part is enabled. output current to a certain safe level namely ILIMIT. At the instance the overload occurs, higher current may flow for a very short period of time before the current limit Short-circuit or overload Short-circuit or overcurrent function can react. 2 condition that occurs when condition After the current limit function has tripped (reached the the part is enabled. overcurrent trip threshold), the device switches into current limiting mode and the current is clamped at ILIMIT. Gradual increase from nominal Load increases gradually The current rises until ITRIG or thermal limit. Once the 3 until the current-limit threshold has been reached, the device switches into its operating current to ILIMIT threshold.(ITRIG) current limiting mode and is set at ILIMIT. Note that when the output has been shorted to GND at an extremely low temperature (< -20°C), a minimum 120-µF electrolytic capacitor on the output pin is recommended. A correct capacitor type with capacitor voltage rating and temperature characteristics must be properly chosen so that capacitance value does not drop too low at the extremely low temperature operation. A recommended capacitor should have temperature characteristics of less than a 10% variation of capacitance change when operated at extremely low temperatures. Our recommended aluminum electrolytic capacitor type is Panasonic FC series. Thermal Protection Thermal protection prevents the IC from damage when the die temperature exceeds safe margins. This mainly occurs when heavy-overload or short-circuit faults are present for extended periods of time. The AP2181D/AP2191D implements thermal sensing to monitor the operating junction temperature of the power distribution switch. Once the die temperature rises to approximately 140°C, the Thermal protection feature gets activated as follows: The internal thermal sense circuitry turns the power switch off and the FLG output is asserted thus preventing the power switch from damage. Hysteresis in the thermal sense circuit allows the device to cool down to approximately 25°C before the output is turned back on. The built-in thermal hysteresis feature avoids undesirable oscillations of the thermal protection circuit. The switch continues to cycle in this manner until the load fault is removed, resulting in a pulsed output. The FLG open-drain output is asserted when an overcurrent occurs with 7-ms deglitch. Reverse Current Protection In a normal MOSFET switch, current can flow in reverse direction (from the output side to the input side) when the output side voltage is higher than the input side, even when the switch is turned off. A reverse-current blocking feature is implemented in the AP21x1 series to prevent such back currents. This circuit is activated by the difference between the output voltage and the input voltage. When the switch is disabled, this feature blocks reverse current flow from the output back to the input.

AP2181D/AP2191D Application Note (continued) Special Functions: Discharge Function When enable is de-asserted, the discharge function is active. The output capacitor is discharged through an internal NMOS that has a discharge resistance of 100Ω. Hence, the output voltage drops down to zero. The time taken for discharge is dependent on the RC time constant of the resistance and the output capacitor. FLG Response The FLG open-drain output goes active low for any of the two conditions: Overcurrent or Over-Temperature. The time from when a fault condition is encountered to when the FLG output goes low is 7-ms (TYP). The FLG output remains low until both overcurrent and over-temperature conditions are removed. Connecting a heavy capacitive load to the output of the device can cause a momentary overcurrent condition, which does not trigger the FLG due to the 7-ms deglitch timeout. This 7-ms timeout is also applicable for overcurrent recovery and Thermal recovery. The AP2181D/AP2191D is designed to eliminate erroneous overcurrent reporting without the need for external components, such as an RC delay network. Power Supply Considerations A 0.01-µF to 0.1-µF X7R or X5R ceramic bypass capacitor between IN and GND, close to the device, is recommended. This limits the input voltage drop during line transients. Placing a high-value electrolytic capacitor on the input (10-µF minimum) and output pin(s) is recommended when the output load is heavy. This precaution also reduces power-supply transients that may cause ringing on the input. Additionally, bypassing the output with a 0.01-µF to 0.1-µF ceramic capacitor improves the immunity of the device to short-circuit transients. This capacitor also prevents output from going negative during turn-off due to inductive parasitics. Power Dissipation and Junction Temperature The low on-resistance of the internal MOSFET allows the small surface-mount packages to pass large current. Using the maximum operating ambient temperature (TA) and RDS(ON), the power dissipation can be calculated by: PD = RDS(ON)× I2 The junction temperature can be calculated by: TJ = PD x RθJA + TA Where: TA= Ambient Temperature °C RθJA = Thermal Resistance PD = Total Power Dissipation Generic Hot-Plug Applications In many applications it may be necessary to remove modules or PC boards while the main unit is still operating. These are considered hot-plug applications. Such implementations require the control of current surges as seen by the main power supply and the card being inserted. The most effective way to control these surges is to limit and slowly ramp up the current and voltage being applied to the card, similar to the way in which a power supply normally turns on. Due to the controlled rise and fall times of the AP2181D/AP2191D, these devices can be used to provide a softer start-up to devices being hot-plugged into a powered system. The UVLO feature of the AP2181D/AP2191D also ensures that the switch is off after the card has been removed, and that the switch is off during the next insertion. By placing the AP2181D/AP2191D between the VCC input and the rest of the circuitry, the input power reaches these devices first after insertion. The typical rise time of the switch is approximately 1ms, providing a slow voltage ramp at the output of the device. This implementation controls the system surge current and provides a hot-plugging mechanism for any device. Dual-Purpose Port Applications AP2181D/AP2191D is not recommended for use in dual-purpose port applications in which a single port is used for data communication between the host and peripheral devices while simultaneously maintaining a charge to the battery of the peripheral device. An example of such a non- recommended application is a shared HDMI/MHL (Mobile High-definition Link) port that allows streaming video between an HDTV or set-top box and a smartphone or tablet while maintaining a charge to the smartphone or tablet battery. Since the AP2181D/AP2191D includes an embedded discharge feature that discharges the output load of the device when the device is disabled, the batteries of the connected peripheral device will be subject to continual discharge whenever the AP2181D/AP2191D is disabled. In addition, if the output of the AP2181D/AP2191D is subjected to a constant voltage that would be present during a dual-purpose port application such as MHL, an overstress condition to the device’s discharge MOS transistor may result.
