Output

3.1

Supply Input (VDD)

VDD is the bias supply input for the MOSFET driver and

has a voltage range of 4.5V to 18V. This input must be

decoupled to ground with a local capacitor. This bypass

capacitor provides a localized low-impedance path for

the peak currents that are provided to the load.

3.2

Control Input (IN)

The MOSFET driver input is a high-impedance,

TTL/CMOS compatible input. The input also has

hysteresis between the high and low input levels,

allowing them to be driven from slow rising and falling

signals and to provide noise immunity.

3.3

Ground (GND)

Ground is the device return pin. The ground pin should

have a low-impedance connection to the bias supply

source return. When the capacitive load is being

discharged, high peak currents will flow out of the

ground pin.

3.4

Output (OUT, OUT)

The output is a CMOS push-pull output that is capable

of sourcing and sinking 1.5A of peak current

(VDD = 18V). The low output impedance ensures the

gate of the external MOSFET stays in the intended

state even during large transients. This output also has

a reverse current latch-up rating of 500 mA.
