TC4420/TC4429
3.0
The descriptions of the pins are listed in Table 3-1.
TABLE 3-1:
3.1
The V
and is rated for 4.5V to 18V with respect to the ground
pins. The V
a local ceramic capacitor. The value of the capacitor
should be chosen based on the capacitive load that is
being driven. A minimum value of 1.0 µF is suggested.
3.2
The MOSFET driver input is a high-impedance,
TTL/CMOS compatible input. The input circuitry of the
TC4420/TC4429 MOSFET driver also has a “speed-
up” capacitor. This helps to decrease the propagation
delay times of the driver. Because of this, input signals
with slow rising or falling edges should not be used, as
this can result in double-pulsing of the MOSFET driver
output.

3.3
The MOSFET driver output is a low-impedance,
CMOS, push-pull style output capable of driving a
capacitive load with 6.0A peak currents. The MOSFET
driver output is capable of withstanding 1.5A peak
reverse currents of either polarity.
3.4
The ground pins are the return path for the bias current
and the high peak currents that discharge the load
capacitor. The ground pins should be tied into a ground
plane or have very short traces to the bias supply
source return.
3.5
The exposed metal pad of the 6x5 DFN package is not
internally connected to any potential. Therefore, this
pad can be connected to a ground plane or other
copper plane on a printed circuit board (PCB) to aid in
heat removal from the package.
