Description

VCC

1

IC power supply. A voltage comprised between 10 V and 18 V can be connected

between this pin and GND to supply the IC.

GND

2

Reference voltage connection.

IN

3

Digital input signal for driver.

It is internally pulled down to GND with a 100 k

 (typ.) equivalent resistor.

IN_TH

4

Input for the IN pin's threshold definition: a voltage can be applied obtaining the

values for VIH and VIL.

OUT

5

MOSFET gate drive sourcing / sinking output controlled by the IN pin.

A pull-down equivalent resistor [50 k

 (typ.)] is present.
