The ATA6823 is designed for several body and powertrain applications. The IC isused to drive a continuous current motor in a full H-bridge configuration. An externalmicrocontroller controls the driving function of the IC by providing a PWM signal and adirection signal and allows the use of the IC in a motor-control application. The PWMcontrol is performed by the low-side switch; the high-side switch is permanently on inthe driving phase. The VMODE configuration pin can be set to 5V or 3.3V mode (forregulator 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 10%. For communication a LIN transceiver 2.0 isintegrated.
