Microchip Technology, Inc. High Temperature Triple Half-bridge Driver with SPI Control andPWM ATA6832C

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. SOI technology allows junction temperatures of up to 200°C and enables new cost effective board design possibilities to achieve complex mechatronic solutions. Additional Features Supply voltage up to 40V RDSon typically 0.8Ω at 25°C, maximum 1.8Ω 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
