Highly Integrated Motor Driver Saves Board Space

The M81500FP is a high-voltage, three-phase motor driver fabricated using a 500-V high-power Silicon-On-Insulator process. The single-chip, intelligent power module employs a compact SMD package to reduce the pc-board space required to 11.93 by 17.5 mm and to simplify the board production process. The module integrates a level-shift high-side driver, a low-side driver, bootstrap diodes, IGBTs, and freewheel diodes. Also included are protective functions for over-current, under-voltage, and thermal-shutdown conditions. The driver features a 500-V floating supply voltage. Typical applications include exhaust fans, dishwashers, air conditioners, small servo motors, and small motor controls. Samples of the M81500FP are available from stock to 12 weeks. Pricing in quantities of 1000 is $4.71. POWEREX, Youngwood, PA. (724) 925-7272.
