• Supply Voltage up to 40V • RDSon Typically at 25°C, Maximum 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 25 kHz for Each High-side Output Controlled by External PWM Signal • No Shoot-through Current • Very Low Quiescent Current IVS < 5 µA in Standby Mode over Total Temperature Range • Outputs Short-circuit Protected • Selective Overtemperature Protection for Each Switch and Overtemperature 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 2 MHz Clock Frequency • QFN18 Package Triple Half-bridge Driver with SPI and PWM ATA6831 The ATA6831 provides fully protected driver interfaces designed in SOI technology. They are used to allow a microcontroller to control up to 3 different loads in automotive and industrial applications. Each of the 3 high-side and 3 low-side drivers is capable of driving currents up to 1.0A. Due to the enhanced PWM signal up to 25 kHz it is possible to generate a smooth control of, for example, a DC motor without any noise. The drivers are internally connected to form 3 half-bridges and can be controlled separately from a standard serial data interface, enabling all kinds of loads, such as bulbs, resistors, capacitors and inductors, to be combined. The IC design especially supports the application of H-bridges to drive DC motors. Protection is guaranteed with respect to short-circuit conditions, overtemperature and undervoltage. Various diagnostic functions and a very low quiescent current in standby mode enable a wide range of applications. Automotive qualification protection against conducted interferences, EMC protection and 2-kV ESD protection gives added value and enhanced quality for exacting requirements of automotive applications.
