ATA6823C

In Production

ATA6823C is designed for automotive 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 2.1 is integrated.

 

    Features

        • 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
        • 5V/3.3V regulator and current limitation function
        • Reset derived from 5V/3.3V regulator output voltage
        • Sleep mode with supply current of typically < 45μA, wake-up by signal on pins EN2 or on LIN interface
        • A programmable window watchdog
        • Battery overvoltage protection and battery undervoltage management
        • Overtemperature warning and protection (shutdown)
        • LIN 2.1 compliant
        • 3.3V/5V regulator with trimmed band gap
        • QFN32 package
