BLDC Motor Driver and LIN System Basis Chip

More Documents...

System basis chip for three-phase brushless DC motor controllers designed in the Atmel 0.8-µm SOI technology SMART-I.S.™. The chip forms a BLDC motor control unit for automotive applications in combination with a microcontroller and six discrete power MOSFETs. Works in extended supply voltage range from 5.25V up to 32V.It features a Tjunction of up to 150°C. Its circuits provide a 3.3V/5V linear regulator and a window watchdog. It includes various control and protection functions like overvoltage and over-temperature protection, adjustable short circuit detection, undervoltage management and coast function. Its drivers fulfill maximum safety requirements and offer a high integration level to save cost and space.
