The IC is used to drive a continuous current motor in a full H-bridge configuration. An external microcontroller controls the driving function of the IC by providing a PWM signal and a direction signal and allows the use of the IC in a motor-control application. The PWM control is performed by the low-side switch the high-side switch is permanently on in the driving phase. The VMODE configuration pin can be set to 5V or 3.3V mode for regulator and interface high level . The window watchdog has a programmable time, programmable by choosing a certain value of the external watchdog resistor RWD, internally trimmed to an accuracy of For communication a LIN transceiver is integrated.
