Microchip Technology (Chandler, AZ) offers the MCP8025 and MCP8026 3-phase brushless DC (BLDC) motor gate drivers with integrated power module, LIN transceiver, and sleep mode. The devices can power the dsPIC® digital signal controllers (DSCs) and PIC® microcontrollers (MCUs), 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.
The drivers feature 150 °C ambient temperature, low sleep current of 5 μA (typ.) and an on-chip LIN transceiver that is compliant with the LIN Bus 2.1 and SAE J2602 standards, as well as the previous-generation LIN 1.X standards.
