Block diagram and pin description

17

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

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 13: Truth

table in fault conditions (detected on OUTA)).

CS

Analog current sense output. This output delivers a current proportional to the motor

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

resistor.
