Microchip adds complete 3-phase BLDC motor drive capability
Increased flexibility comes with configurable driver dead-time management, driver blanking-time control, and Over-Current Limit (OCL) for external MOSFETs; the device is suitable for harsh conditions such as industrial & automotive under-hood applications, Microchip says.
The MCP8024 includes functions that power dsPIC Digital Signal Controllers (DSCs) and PIC microcontrollers (MCUs) with capabilities to drive six N-channel MOSFETs. It operates across a voltage range of 6V to 28V and can withstand transient voltage up to 48V. The device provides high-integration analogue functions, such as three current-sensing operational amplifiers; an over-current comparator; MOSFET drivers and a bidirectional communication interface for a complete motor system design. An adjustable step-down DC-to-DC converter powers a broad range of microcontrollers. 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 in thermally-enhanced 40-pin QFN 5 x 5 mm and 48-pin TQFP 7 x 7 mm packages. Use it 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 the MCP8024 TQFP BLDC Motor Driver Evaluation Board (ADM00557) at $99.00.
