- New three-phase BLDC motor gate driver with power module provides all the power, sensing and protection functions needed to implement a robust, highly-efficient solution
- Integrates voltage regulators, current-sensing amplifiers and over-current protection
- Increases flexibility with configurable driver dead-time management, driver blanking-time control, and Over-Current Limit (OCL) for external MOSFETs
- Suitable for harsh conditions such as industrial & automotive under-hood applications
Microchip announces a new three-phase BLDC motor gate driver with power module: the MCP8024. This new device includes functions that power dsPIC® Digital Signal Controllers (DSCs) and PIC® microcontrollers (MCUs) with capabilities to drive six N-channel MOSFETs. Customers can implement improved performance and high 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. The configurable driver dead-time management; driver blanking-time control; and Over-Current Limit (OCL) for external MOSFETs, offer a significant increase in flexibility. 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. The MCP8024 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
(ADM00557) priced at $99.00. The MCP8024 is available now for sampling and volume production.
