Output

Fault Status

(Active Low)

This output pin is an open drain indication that goes active low when a

fault mode is detected by the device.

2, 24

VPWR

Input

Positive Power Supply

These pin connects to the positive power supply and are the source input

of operational power for the device. Pins 2 and 24 must be shorted

together on the board.

Output

Low-Side Output 4

Low-Side Output 6

Low-Side Output 8

Low-Side Output 10

These outputs are current and thermal overload protected. Maximum

steady state current through each of these outputs is 500 mA.

4, 11, 15,

GND

Ground

Power Ground

These pins serve as the ground for the source of the low-side output

transistors as well as the logic portion of the device. Pins 4, 11, 15, 20,

and 32 must be shorted together on the board
