ATA6831C

In Production

Fully protected triple half bridge driver designed in SOI technology that allows especially the control of motors by a microcontroller in automotive and industrial applications. Each of the three high-side and three low-side drivers, internally connected to form three half-bridges, can drive currents up to 1.0A. Its high PWM frequency capability can smoothly control two DC motors or a BLDC motor.

 

    Features

        • Supply voltage up to 40V
        • RDSon typically 0.8Ω at 25°C, maximum 1.5Ω at 150°C
        • Up to 1.0A output current
        • Three half-bridge outputs formed by three high-side and three low-side drivers
        • Capable of switching loads such as DC motors, bulbs, resistors, capacitors, and inductors
        • PWM capability up to 25kHz for each high-side output controlled by external PWM signal
        • No shoot-through current
        • Very low quiescent current IVS < 2μA in standby mode over total temperature range
        • Outputs short-circuit protected
        • Selective overtemperature protection for each switch and over temperature prewarning
        • Undervoltage protection
        • Various diagnostic functions such as shorted output, open load, overtemperature and power-  supply fail detection
        • Serial data interface, daisy chain capable, up to 2MHz clock frequency
        • QFN18 package
