F A Applications Information N 3 2 Input Thresholds VDD 1 3 The FAN3213 and the FAN3214 drivers consist of two / identical channels that may be used independently at F rated current or connected in parallel to double the A N individual current capacity. 3 2 The input thresholds meet industry-standard TTL-logic Input 1 thresholds independent of the VDD voltage, and there is stage VOUT 4 a hysteresis voltage of approximately 0.4 V. These — levels permit the inputs to be driven from a range of D input logic signal levels for which a voltage over 2 V is u considered logic HIGH. The driving signal for the TTL a l - inputs should have fast rising and falling edges with a 4 slew rate of 6 V/µs or faster, so a rise time from 0 to A , 3.3 V should be 550 ns or less. With reduced slew rate, Figure 28.

This hysteresis helps prevent i the inputs and outputs shown in the block diagram of d each part (see Figure 4 and Figure 5). In these cases, chatter when low VDD supply voltages have noise from e the power switching. This configuration is not suitable G the actual static I current is the value obtained from DD for driving high-side P-channel MOSFETs because the a the curves plus this additional current. low output voltage of the driver would turn the P-channel te MillerDrive™ Gate Drive Technology MOSFET on with VDD below 3.9 V. D r FAN3213 and FAN3214 gate drivers incorporate the V Bypass Capacitor Guidelines iv DD e MillerDrive™ architecture shown in Figure 28. For the To enable this IC to turn a device ON quickly, a local r output stage, a combination of bipolar and MOS devices s high-frequency bypass capacitor, C , with low ESR and provide large currents over a wide range of supply BYP ESL should be connected between the VDD and GND voltage and temperature variations. The bipolar devices pins with minimal trace length. This capacitor is in carry the bulk of the current as OUT swings between 1/3 addition to bulk electrolytic capacitance of 10 µF to 47 µF to 2/3 V and the MOS devices pull the output to the DD commonly found on driver and controller bias circuits. HIGH or LOW rail. A typical criterion for choosing the value of C is to The purpose of the MillerDrive™ architecture is to BYP keep the ripple voltage on the V supply to ≤ 5%. This speed up switching by providing high current during the DD is often achieved with a value ≥ 20 times the equivalent Miller plateau region when the gate-drain capacitance of load capacitance C , defined here as Q /V . the MOSFET is being charged or discharged as part of EQV GATE DD Ceramic capacitors of 0.1 µF to 1 µF or larger are the turn-on / turn-off process. common choices, as are dielectrics, such as X5R and For applications with zero voltage switching during the X7R, with good temperature characteristics and high MOSFET turn-on or turn-off interval, the driver supplies pulse current capability. high peak current for fast switching even though the If circuit noise affects normal operation, the value of Miller plateau is not present. This situation often occurs C may be increased, to 50-100 times the C , or in synchronous rectifier applications because the body BYP EQV C may be split into two capacitors. One should be a diode is generally conducting before the MOSFET is BYP larger value, based on equivalent load capacitance, and switched ON. the other a smaller value, such as 1-10 nF mounted The output pin slew rate is determined by V voltage closest to the VDD and GND pins to carry the higher- DD and the load on the output. It is not user adjustable, but frequency components of the current pulses. The a series resistor can be added if a slower rise or fall time bypass capacitor must provide the pulsed current from at the MOSFET gate is needed. both of the driver channels and, if the drivers are switching simultaneously, the combined peak current sourced from the C would be twice as large as when BYP a single channel is switching. © 2008 Fairchild Semiconductor Corporation www.fairchildsemi.com FAN3213 / FAN3214 • Rev. 1.9 12

F A Layout and Connection Guidelines N 3 The FAN3213 and FAN3214 gate drivers incorporate Figure 30 shows the current path when the gate driver 2 fast-reacting input circuits, short propagation delays, turns the MOSFET OFF. Ideally, the driver shunts the 1 3 and powerful output stages capable of delivering current current directly to the source of the MOSFET in a small / peaks over 4 A to facilitate voltage transition times from circuit loop. For fast turn-off times, the resistance and F under 10 ns to over 150 ns. The following layout and inductance in this path should be minimized. A connection guidelines are strongly recommended: N V V 3  Keep high-current output and power ground paths DD DS 21 separate from logic input signals and signal ground 4 — paths. This is especially critical for TTL-level logic C thresholds at driver input pins. BYP D  Keep the driver as close to the load as possible to FAN321x ua minimize the length of high-current traces. This l- 4 reduces the series inductance to improve high- A speed switching, while reducing the loop area that , can radiate EMI to the driver inputs and PWM H i surrounding circuitry. g h  If the inputs to a channel are not externally -S connected, the internal 100 k resistors indicated p Figure 30. Current Path for MOSFET Turn-Off e on block diagrams command a low output. In noisy e environments, it may be necessary to tie inputs of d , an unused channel to VDD or GND using short L traces to prevent noise from causing spurious o w output switching. - S  Many high-speed power circuits can be susceptible i d to noise injected from their own output or other e external sources, possibly causing output re- G triggering. These effects can be obvious if the a t circuit is tested in breadboard or non-optimal circuit e layouts with long input or output leads. For best D results, make connections to all pins as short and r i v direct as possible. e r  FAN3213 and FAN3214 are pin-compatible with s many other industry-standard drivers.  The turn-on and turn-off current paths should be minimized, as discussed in the following section. Figure 29 shows the pulsed gate drive current path when the gate driver is supplying gate charge to turn the MOSFET on. The current is supplied from the local bypass capacitor, C , and flows through the driver to BYP the MOSFET gate and to ground. To reach the high peak currents possible, the resistance and inductance in the path should be minimized. The localized C acts BYP to contain the high peak current pulses within this driver- MOSFET circuit, preventing them from disturbing the sensitive analog circuitry in the PWM controller.
