  • (1888PressRelease) October 09, 2014 - New Delhi, India - Microchip Technology Inc., a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions, has added two new 3-phase brushless DC (BLDC) motor gate drivers with integrated power module, LIN transceiver and Sleep mode - the MCP8025 and MCP8026 (MCP8025/6). These devices can power a broad range of Microchip's dsPIC® Digital Signal Controllers (DSCs) and PIC® Microcontrollers (MCUs), complementing their control algorithms by driving MOSFETs, sensing current, preventing short circuits, outputting zero crosses, controlling dead time and blanking time, and monitoring for fault conditions such as over/under-voltage, over-temperature and other thermal warnings. This combination enables Microchip to provide a complete motor control and drive solution for a broad range of automotive and industrial applications. Additionally, the new drivers' 150 degrees Celsius ambient temperature, low sleep current of 5 µA (typ.) and LIN transceiver make them particularly well suited for automotive designs, such as those that operate under the hood (e.g., pumps and HVAC blowers) or need to reduce key-off power consumption. The on-chip LIN transceiver is compliant with the LIN Bus 2.1 and SAE J2602 standards, as well as the previous-generation LIN 1.X standards.

    According to IMS Research, motor-based applications are moving from brushed to brushless, with the CAGR for BLDC motors projected to be twice that of the overall motor market. The MCP8025/6 are highly integrated brushless motor drivers that reduce the resources needed from the MCU or DSC used for control, thus lowering both component counts and overall BOM costs while providing maximum design flexibility. For example, these drivers integrate a LIN transceiver, voltage regulator, op amp and over-current comparator, along with configurable housekeeping functions. Battery-powered or energy-efficient motor applications in the industrial and automotive sectors can benefit from the combination of their 5 µA (typ.) Sleep mode, as well as the drivers' low-power standby mode, which enables them to act as either Master or Slave. Additionally, the MCP8025/6's adjustable buck regulator is among the industry's most efficient for stepping down from 12V supplies to power 3V and 5V MCUs.

    "The automotive and industrial markets continue to demand motor drive and control solutions with higher performance, integration and flexibility, along with reduced cost, complexity and time to market," said Bryan J. Liddiard, marketing vice president of Microchip's Analog and Interface Products Division. "The MCP8025/6 drivers' rich feature set and low-power modes make them ideal for pairing with a broad range of MCUs and DSCs. In combination with our large portfolio of dsPIC DSCs and PIC MCUs, Microchip provides customers with complete motor system solutions."

    Development support
    The MCP8025 driver is supported by Microchip's MCP8025 TQFP BLDC Motor Driver Evaluation Board (Part # ADM00600), which is available now.

    The MCP8025 and MCP8026 three-phase BLDC motor gate drivers are both available now for sampling and volume production, in 40-pin, 5x5 mm QFN and 48-pin, 7x7 mm TQFP packages, each in 5,000-unit quantities.
