TERMINAL FUNCTIONS

TERMINAL

I/O DESCRIPTION

NO. NAME

1 NC No connection. Should be grounded.

Input A. Input signal of the A driver. Has logic-compatible threshold and hysteresis. If not used, this input

2 INA I

should be tied to either V

or GND. It should not be left floating.

Common ground. Should be connected very closely to the source of the power MOSFET that the driver

3 GND

is driving.

Input B. Input signal of the A driver. Has logic-compatible threshold and hysteresis. If not used, this input

4 INB I

should be tied to either V

or GND. It should not be left floating.

5 OUTB O Driver output B. The output stage can provide 4-A drive current to the gate of a power MOSFET.

6 VDD I Supply. Supply voltage and the power input connection for this device.

7 OUTA O Driver output A. The output stage can provide 4-A drive current to the gate of a power MOSFET.

8 NC No connection. Should be grounded.
