1. Description

The ATA6823 is designed for several body and powertrain applications. 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 10%. For communication a LIN transceiver 2.0 is

integrated.

PWM and Direction-controlled Driving of Four Externally-powered NMOS Transistors

A Programmable Dead Time Is Included to Avoid Peak Currents Within the H-bridge

Integrated Charge Pump to Provide Gate Voltages for High-side Drivers and to Supply

the Gate of the External Battery Reverse Protection NMOS
