Three-phase brushless driver includes a power module

Microchip has announced a three-phase BLDC motor gate driver with power module. The MCP8024 includes functions that power dsPIC DSCs (digital signal controllers) and PIC microcontrollers with capabilities to drive six N-channel MOSFETs. 

It operates across 6 to 28V and can withstand transient voltage up to 48V.  The device provides high-integration analogue, such as three current-sensing operational amplifiers; an over-current comparator; MOSFET drivers and bi-directional communication interface.

The configurable driver dead-time management; driver blanking-time control; and over-current limit for external MOSFETs are claimed to offer a significant increase in flexibility.  The adjustable step-down DC/DC converter powers a range of microcontrollers.

The wide operating temperature - from -40 to 150°C - allows for usage in harsh environments such as automotive under-hood applications.

The MCP8024 TQFP BLDC motor drive evaluation board (ADM00557) is also available.
