BD52xx series BD53xx series Application Information Explanation of Operation For both the open drain type (Fig.15) and the CMOS output type (Fig.16), the detection and release voltages are used as threshold voltages. When the voltage applied to the VDD pins reaches the applicable threshold voltage, the VOUT terminal voltage switches from either “High” to “Low” or from “Low” to “High”. Please refer to the Timing Waveform and Electrical Characteristics for information on hysteresis. Because the BD52xx series uses an open drain output type, it is necessary to connect a pull-up resistor to VDD or another power supply if needed [The output “High” voltage (VOUT) in this case becomes VDD or the voltage of the other power supply].

Timing Waveforms Example: the following shows the relationship between the input voltage VDD, the CT Terminal Voltage VCT and the output voltage VOUT when the input power supply voltage VDD is made to sweep up and sweep down (The circuits are those in Figure.15 and 16). 1 When the power supply is turned on, the output is unstable VDD from after over the operating limit voltage (VOPL) until tPHL.

BD52xx series BD53xx series Circuit Applications 1) Examples of a common power supply detection reset circuit VDD1 VDD2 Application examples of BD52xx series (Open Drain output type) and BD53xx series (CMOS output type) are RL shown below. Micro BD52xx RST controller CASE1: Power supply of the microcontroller (VDD2) CT differs from the power supply of the reset detection C L (VDD1). （Noise-filtering Use an open drain output type (BD52xx) device with a Capacitor） GND load resistance RL attached as shown Fig.18. Fig.18 Open Drain Output Type CASE2: Power supply of the microcontroller (VDD1) is the same as the power supply of the reset detection (VDD1). VDD1 Use a CMOS output type (BD53xx) device or an open drain output type (BD52xx) device with a pull up resistor between the output and VDD1. Micro BD53xx RST controller When a capacitance CL for noise filtering is connected to the VOUT pin (the reset signal input terminal of the CT microcontroller), please take into account the waveform C L of the rise and fall of the output voltage (VOUT). （Noise-filtering Capacitor） Please refer to Operational Notes for recommendations GND on resistor and capacitor values.

BD52xx series BD53xx series 3) Examples of the power supply with resistor dividers In applications wherein the power supply voltage of an IC comes from a resistor divider circuit, an in-rush current will flow into the circuit when the output level switches from “High” to “Low” or vice versa. In-rush current is a sudden surge of current that flows from the power supply (VDD) to ground (GND) as the output logic changes its state. This current flow may cause malfunction in the systems operation such as output oscillations, etc. V1 Figure.21 IDD R2 I1 Inrush Current VDD BD52xx R1 CIN BD53xx VOUT CL GND VDD 0 VDET Fig.21 Resistor Divider Connection Application When an in-rush current (I1) flows into the circuit (Refer to Fig. 21) at the time when output switches from “Low” to “High”, a voltage drop of I1×R2 (input resistor) will occur in the circuit causing the VDD supply voltage to decrease. When the VDD voltage drops below the detection voltage, the output will switch from “High” to “Low”. While the output voltage is at “Low” condition, in-rush current will stop flowing and the voltage drop will be reduced. As a result, the output voltage will switches again from “Low” to “High” which causes an in-rush current and a voltage drop. This operation repeats and will result to oscillation.

BD52xx series BD53xx series Operational Notes 1) Absolute maximum ratings Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit between pins. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings. 2) Ground Voltage The voltage of the ground pin must be the lowest voltage of all pins of the IC at all operating conditions. Ensure that no pins are at a voltage below the ground pin at any time, even during transient condition. 3) Recommended operating conditions These conditions represent a range within which the expected characteristics of the IC can be approximately obtained. The electrical characteristics are guaranteed under the conditions of each parameter. 4) Bypass Capacitor for Noise Rejection To help reject noise, put a 1µF capacitor between VDD pin and GND and 1000pF capacitor between VOUT pin and GND. Be careful when using extremely big capacitor as transient response will be affected. 5) Short between pins and mounting errors Be careful when mounting the IC on printed circuit boards. The IC may be damaged if it is mounted in a wrong orientation or if pins are shorted together. Short circuit may be caused by conductive particles caught between the pins. 6) Operation under strong electromagnetic field Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction. 7) The VDD line impedance might cause oscillation because of the detection current. 8) A VDD to GND capacitor (as close connection as possible) should be used in high VDD line impedance condition. 9) Lower than the mininum input voltage puts the VOUT in high impedance state, and it must be VDD in pull up (VDD) condition. 10) External parameters The recommended value of RL Resistor is 50kΩ to 1MΩ. The recommended value of CT Capacitor is over 100pF to 0.1µF. There are many factors (board layout, etc) that can affect characteristics. Please verify and confirm using practical applications. 11) Power on reset operation Please note that the power on reset output varies with the VDD rise time. Please verify the behavior in the actual operation. 12) Testing on application boards When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may subject the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply should always be turned off completely before connecting or removing it from the test setup during the inspection process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during transport and storage. 13) Rush current When power is first supplied to the IC, rush current may flow instantaneously. It is possible that the charge current to the parasitic capacitance of internal photo diode or the internal logic may be unstable. Therefore, give special consideration to power coupling capacitance, power wiring, width of GND wiring, and routing of connections. 14) CT pin discharge Due to the capabilities of the CT pin discharge transistor, the CT pin may not completely discharge when a short input pulse is applied, and in this case the delay time may not be controlled. Please verify the actual operation. . www.rohm.com TSZ02201-0GJG0G300040-1-2 © 2013 ROHM Co., Ltd. All rights reserved. 13/13 TSZ22111・15・001 29.May.2017 Rev.007
