Atmel’s ATA6843 and ATA6844 are a set of highly integrated gate driver integrated circuits (ICs). The devices are new members of the company’s gate driver family designed for three-phase brushless dc (BLDC) motor-control applications, including turbochargers, waste gates, exhaust gas recirculation, pumps, fans, power window, power doors, and power seats. Featuring six-output stages for direct motor control when combined with an Atmel AVR microcontroller, the devices also have on-chip Atmel automotive local interconnect network transceiver Internet protocol for in-car communication. According to Atmel, the new driver ICs are the only products in the industry to incorporate all the essential functional blocks to supply and monitor a microcontroller in BLDC motor-control applications. In addition, the Atmel ATA6844 is a high-temperature version to operate at chip temperatures of up to 200°C (392°F).
