Microchip announces a new three-phase brushless (BLDC) motor gate controller with power module: the MCP8024. This new device incorporates features that give dsPIC® Digital Signal Controllers (DSCs) and PIC® microcontrollers the capabilities to drive six N-channel MOSFETs. thus an increase in efficiency and a reduction in the cost of the system as well as a shortening of the commercialization period.
The MCP8024 works with a wide voltage range from 6V to 28V and can withstand transient voltages up to 48V. The device provides highly integrated analog electronics, such as three current-sensing op amps; an overcurrent comparator; MOSFET drivers and bi-directional communication interface for complete motor system design. Configurable controller dead time management, controller clear time control, and Over-Current Limit (OCL) for external MOSFETs offer a significant increase in flexibility. The adjustable buck DC/DC converter powers a wide variety of microcontrollers with the efficiency advantages of a switching power supply. In addition, its wide range of working temperatures, between -40°C and +150°C (H-temp), allows the use of the MCP8024 in harsh environments such as applications under the hood of the car.
The MCP8024 is supplied in thermally advanced 5mm x 5mm QFN packages and
40-pin and 7mm x 7mm 48-pin TQFP. The MCP8024 is indicated for a wide variety of applications in the automotive market, such as fans and air conditioning pumps, and within the industrial market, such as fans, motion control, robotics and others.
The MCP8024 is supported by Microchip's MCP8024 (TQFP BLDC Motor Driver Evaluation Board) evaluation board (ADM00557) priced at $99.00. The MCP8024 is now available for sampling and volume production.
