Chandler, Ariz., — Microchip Technology Inc. introduces a three-phase BLDC motor gate driver with power module. The MCP8024 device includes functions that power dsPIC digital signal controllers (DSCs) and PIC microcontrollers (MCUs) with capabilities to drive six N-channel MOSFETs. This provides increased efficiency, while lowering system cost and 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 analog such as three current-sensing operational amplifiers, an over-current comparator, MOSFET drivers and a bidirectional communication interface for a complete motor control and drive 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, said Microchip. In addition, the adjustable step-down DC-to-DC converter powers a broad range of microcontrollers, with the efficiency benefits of a switch-mode power supply. 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-the-hood applications.
The MCP8024 is available in thermally enhanced 40-pin QFN 5- x 5-mm and 48-pin TQFP 7-x 7-mm packages. The MCP8024 is well suited for a broad range of applications in the automotive market, such as HVAC blowers and pumps, and the industrial market, including fans, motion control and robotics.
“The automotive and industrial markets continue to demand higher performance, higher integration, faster time to market and more flexibility, all in a cost-effective solution,” said Bryan J. Liddiard, marketing vice president of Microchip’s Analog and Interface Products Division, in a statement. “The integrated voltage regulators, current sensing amplifiers and over-current protection make the MCP8024 an ideal candidate to use with a broad range of MCUs, DSCs and FPGAs. By combining with dsPIC DSCs and PIC microcontrollers, Microchip can help solve customers’ problems and provide complete motor solutions.”
Availability: The MCP8024 is available now for sampling and volume production in 40-pin QFN 5- x 5-mm and 48-pin TQFP 7-x 7-mm packages. The MCP8024 is supported by Microchip's MCP8024 TQFP BLDC Motor Driver Evaluation Board (Part # ADM00557), which is expected to be available on December 20.
Pricing: $2.61 each in quantities of 10,000. To purchase products, go to microchipDIRECT or contact one of Microchip's authorized distribution partners. The MCP8024 TQFP BLDC Motor Driver Evaluation Board (Part # ADM00557) is priced at $99.00.
