Card Power-Down
The S39421 provides a turn-on slew-rate of 250V/s and a
fast turn-off performed by internally shorting the VGATE3
and VGATE5 outputs to ground. If the card circuitry or
host power supply cannot accept a fast shutdown then a
CR time constant may be added as shown below. The
resistors in series with the 47nF(X7R) capacitors increase
the discharge time of the MOSFET gates. The values
shown provide a shutdown slew of ~5V/ms. Decreasing
the resistor values increases the shutdown slew-rate, and
vice-versa. The capacitor values may also be increased
but this will decrease the 250V/s turn-on slew-rate.
