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.
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.

Power Ground
These outputs are current and thermal overload protected. Maximum
steady state current through each of these outputs is 500 mA.
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
