3.0
The descriptions of the pins are listed in
TABLE 3-1:
3.1
The V
driver and is rated for 4.5V to 30V with respect to the
ground pins. The V
ground with a local ceramic capacitor. The value of this
capacitor should be chosen based on the capacitive
load that is being driven.
3.2
The MOSFET driver input is a TTL/CMOS compatible
input with 250 mV of hysteresis between the high and
low threshold voltages. If an input signal level of greater
than 12V is applied to the device, a series current
limiting resistor is recommended.
3.3
The lockout pin enables/disables the undervoltage
lockout feature of the device. If undervoltage lockout is
desired (output is not enabled until the bias voltage
reaches 8.4V (typical) on the rising edge and is
disabled when the bias voltage reaches 7.7V (typical)
on the falling edge), the lockout pin should be left float-
ing. If operation below 7V is desired, the lockout pin
should be tied to ground.

3.4
The ground pins are the return path for the bias current
and for the high peak currents which discharge the load
capacitor. Both ground pins should be used to ensure
proper operation. The ground pins should be tied into a
ground plane or have short traces to the bias supply
source return.
3.5
The TC4431/TC4432 devices have individual source
and sink output pins. This feature can be used to adjust
the rise and fall time independently by adding separate
charge and discharge resistors external to the device.
Pin 7 (source output) can source 3 A peak currents into
capacitive loads and pin 6 (sink output) can sink 1.5 A
peak currents from a capacitive load.
