05 April 2011 Gate driver ICs target BLDC motor control applications Atmel has introduced a new set of highly integrated system basis gate driver ICs. The ATA6843 and ATA6844 devices are additions to the company's existing range of gate drivers, designed for three phase brushless dc (BLDC) motor control applications including turbo chargers, waste gates, EGR, pumps, fans, power window, power doors and power seats. Featuring six output stages for direct motor control (when combined with an Atmel AVR microcontroller) and an on chip Atmel automotive LIN transceiver IP for in car communication, Atmel claims the 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 ATA6844 is optimised to operate at chip temperatures up to 200dC. It is manufactured in Atmel's own BCD-on-SOI technology SMART-I.S. for extreme temperatures and enables direct attachment of the ECU to hot actuators for short wiring and optimised construction. With the devices' six input stages, the mcu individually controls each of the six output stages. It also defines the adjustable overcurrent detection threshold of the ATA6843/44 to enable a current monitoring tailored to the various types of power mosfets used in the application.
