PIN DESCRIPTIONS

The descriptions of the pins are listed in Table 3-1.

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 to be 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 a 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. High peak currents will flow out the

ground pin when the capacitive load is being

discharged.

3.4

Output (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 will stay in the intended

state even during large transients. This output also has

a reverse current latch-up rating of 500 mA.
