Voltage controlled input pins with hysteresis, CMOS compatible. These two pins

to V
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
table in fault conditions (detected on OUTA)
Analog current sense output. 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.
Active high CMOS compatible pin to disable the current sense pin.
