Atmel ATA6832C High Temperature Triple Half-bridge Driver with SPI and PWM PRELIMINARY DATASHEET ● Supply voltage up to 40V ● RDSon typically at 25°C, maximum at 200°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 ● 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 2MHz clock frequency ● QFN18 package The ATA6832C is a fully protected driver IC specially designed for high temperature applications. In mechatronic solutions, for example turbo charger or exhaust gas recirculation systems, many flaps have to be controlled by DC motor driver ICs which are located very close to the hot engine or actuator where ambient temperatures up to 150°C are usual. Due to the advantages of SOI technology junction temperatures up to 200°C are allowed. This enables new cost effective board design possibilities to achieve complex mechatronic solutions. The Atmel ATA6832C is a triple half-bridge driver to control up to three different loads by a microcontroller in automotive and industrial applications. Each of the three high-side and three low-side drivers is capable of driving currents up to 1.0A. Due to the enhanced PWM signal up to 25kHz it is possible to generate a smooth control of, for example, a DC motor without any noise. The drivers are internally connected to form three 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 1.5-kV ESD protection gives added value and enhanced quality for exacting requirements of automotive applications.
