Voltage controlled input pins with hysteresis, CMOS compatible. These two pins control the state of
the bridge in normal operation according to the truth table (brake to V
CC
, Brake to GND, clockwise and
counterclockwise).
Voltage controlled input pin with hysteresis, CMOS compatible. Gates of Low-Side FETS get
modulated by the PWM signal during their ON phase allowing speed control of the motor
Open drain bidirectional logic pins. These pins must be connected to an external pull up resistor.When
externally pulled low, they disable half-bridge A or B. In case of fault detection (thermal shutdown of a
High-Side FET or excessive ON state voltage drop across a Low-Side FET), these pins are pulled low
by the device (see truth table in fault condition).

NAME
DESCRIPTION
LOGIC CONTROL
Allows the turn-on and the turn-off of the High Side and the Low Side
switches according to the truth table.
Shut-down the device outside the range [5.5V..36V] for the battery
voltage.
Protect the High-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 good R
DS(on)
for the
leg of the bridge.
In case of short circuit for the High-Side switch, limits the motor current
by reducing its electrical characteristics.
In case of short-circuit with the increase of the junction’s temperature,
shuts-down the concerned High-Side to prevent its degradation and to
protect the die.
Signalize an abnormal behavior of the switches in the half-bridge A or
B by pulling low the concerned ENx/DIAGx pin.
