Load Current Sense
The backside TAB is connected to the power supply of the MC33288DH.
The Current Sense terminal delivers a ratioed amount (1/1000) of the sum of the currents
that can be used to generate signal ground referenced output voltages for use by the
microcontroller.

STATUS
WLP
Do Not Connect These terminals must not be connected.
OUTPUT Channel 1 They deliver current to the connected loads and are controlled via the IN1 terminals.
OUTPUT Channel 2 They deliver current to the connected loads and are controlled via the IN2 terminals,
Ground
This is the ground terminal of the device.
Status for Both
Channels
The Fault output is an open drain indication that goes active low when a fault mode
(Openload, Overtemperature) is detected by the device.
Warning Lamp Output It delivers current through the connected load.
