Microchip has introduced the MIC4607A MOSFET driver with 35ns propagation delay time and 20ns driver rise/fall time, over a 1nF capacitive load, suitable for motors used in automobiles and industrial automation.
Modern motor drives are becoming more robust, and the MIC4607A supports that by featuring protection features such as:
These features prevent the driver from being affected by supply glitches, high-side ringing below ground and skewing with fast voltage transitions.
The MIC4607A features wettable flanks in a 28-pin 4mm x 5mm VQFN package for reliable bonding to PCB layouts, and operates between -40°C to 125°C.
Part Number: EV42B57A
The EV42B57A evaluation board features the MIC4607 MOSFET driver, capable of driving three-phase brushless dc motors rated up to 20A and 85V. The board supports asymmetric turn-on and turn-off, allowing designers to precisely tune electromagnetic interference (EMI) behavior.
