September 01, 2009 by Jeff Shepard

Allegro MicroSystems, Inc. announced a new fully protected, single chip full-bridge motor driver IC for dc brush motor applications. According to the company, this new solution enhances the user’s system reliability compared to other discrete solutions. Allegro’s SPF7302 is targeted at the automotive and industrial markets.

Allegro’s new motor driver IC includes various integrated protection circuits. There is an externally adjustable delay timer to halt the OCL for proper motor startup. Open load detections are also present at start-up to ensure steady operation of the device. Other key features of this device include: Overvoltage protection (OVP); overcurrent protection (OCP) with latch, which is adapted to the DMOSFETs in each full bridge; undervoltage lockout (UVLO); and overcurrent limitation.

The package is a thermally enhanced 16-pin HSOP power package with an exposed thermal pad on the bottom side of the package. It is priced at $5.10 in quantities of 1,000 and has an 8-week typical lead-time to market.
