Clockwise input. CMOS compatible
PWM input. CMOS compatible.
Output of current sense. This output delivers a current
proportional to the motor current, if CS_DIS is low or left open.
The information can be read back as an analog voltage across
an external resistor.
Status of high-side and low-side switches B; Open drain output.
This pin must be connected to an external pull up resistor. When
externally pulled low, it disables half-bridge B. In case of fault
detection (thermal shutdown of a high-side FET or excessive
ON-state voltage drop across a low-side FET), this pin is pulled
low by the device (see
(detected on OUTA)

Connection to the gate of the external MOS used for the reverse

Allows the turn-on and the turn-off of the high-side and the
low-side switches according to the
Shut down the device outside the range [4.5 V to 24 V] for the
battery voltage.
Protect the high-side and the low-side switches from the
high-voltage on the battery line in all configuration for the motor.
Drive the gate of the concerned switch to allow a proper R
for the leg of the bridge.
Limits the motor current, by reducing the high-side switch
gate-source voltage when short-circuit to ground occurs.
In case of short-circuit with the increase of the junction’s
temperature, it shuts down the concerned driver to prevent its
degradation and to protect the die.
Detects when low-side current exceeds shutdown current and
latches off the concerned low-side.
