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.
These are the device input terminals which directly control their associated outputs.
These terminals are not used.
These terminals must not be connected.
They deliver current to the connected loads and are controlled via the IN1 terminals.
They deliver current to the connected loads and are controlled via the IN2 terminals,
This is the ground terminal of the device.
The Fault output is an open drain indication that goes active low when a fault mode
(Openload, Overtemperature) is detected by the device.
