DIAG
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 outside the range
(4,5...24V).
Protect the high-side and the low-side switches from 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 an abnormal condition 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.
