Three-phase brushless DC companion device offers complete motor system solution

Microchip has launched a new three-phase BLDC motor gate driver with power module: the MCP8024. The device includes functions that power dsPIC Digital Signal Controllers (DSCs) and PIC microcontrollers (MCUs) with capabilities to drive six N-channel MOSFETs. As a result customers are now able to implement improved performance and levels of robustness providing increased efficiency and lowering system cost while reducing time to market.

The MCP8024 operates across a wide voltage range of 6V 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 a bidirectional communication interface for a complete motor system design.

According t Microchip the configurable driver dead-time management; driver blanking-time control; and Over-Current Limit (OCL) for external MOSFETs, offer a significant increase in flexibility and the adjustable step-down DC-to-DC converter powers a broad range of microcontrollers with the efficiency benefits of a switch-mode power supply. In addition, the wide operating temperature range, from -40°C to +150°C (H-temp), allows the MCP8024 to be used in harsh environments such as automotive under-hood applications.

The MCP8024 is available in thermally-enhanced 40-pin QFN 5mm x 5mm and 48-pin TQFP 7mm x 7 mm packages and it is suitable for a broad range of applications in the automotive market, such as HVAC blowers and pumps, and in the industrial market including fans, motion control, robotics, and others.

The MCP8024 is supported by Microchip’s MCP8024 TQFP BLDC Motor Driver Evaluation Board.
