Integrated gate driver ICs suit automotive apps

The Atmel ATA6843 and ATA6844 integrated gate driver ICs suit three-phase brushless dc motor control applications including turbo chargers, waste gates, EGR, pumps, fans, power window, power doors, and power seats. They feature six-output stages for direct motor control when combined with an Atmel AVR microcontroller.

The gate drivers incorporate functional blocks to supply and monitor a microcontroller in BLDC motor control applications. The high-temperature version operates at chip temperatures up to 200°C. The gate driver monitors overtemperature, overvoltage, undervoltage, short-circuit conditions, and charge-pump failures. An on-board integrated watchdog independently monitors the MCU to increase the overall system safety. (Ea/10,000: ATA6843, $2.10; ATA6844, $2.40 — available now.)
