Description

Battery connection.

Power grounds, must always be externally connected together.

Power connections to the motor.

Voltage controlled input pins with hysteresis, CMOS compatible. These two pins control the state of

counterclockwise).

PWM

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).

CS

Analog current sense output. This output sources a current proportional to the motor current. The

information can be read back as an analog voltage across an external resistor.
