Allows the turn-on and the turn-off of the high-side and the
low-side switches according to the truth table.
Shuts down the device for battery voltage lower than 5V.
Protect the high-side and the low-side switches from the
high voltage on the battery line.
Drive the gate of the concerned switch to allow a proper
R
Limits the motor current in case of short circuit.
In case of short-circuit with the increase of the junction
temperature, it shuts down the concerned driver to prevent
degradation and to protect the die.
Detects when low side current exceeds shutdown current
and latches off the concerned Low side.
Signalizes the abnormal behaviour of the switch (output
shorted to ground or output shorted to battery) by pulling
down the concerned ENx/DIAGx pin.
Limits the power dissipation of the high-side driver inside
safe range in case of short to ground condition.
DS(on)
for the leg of the bridge.
