MC33982B Datasheet | Freescale Semiconductor

features . The device is suitable for loads with high inrush current, as well as motors and all types of resistive and inductive loads. Programming, control, and diagnostics are implemented via the Serial Peripheral Interface (SPI). A dedicated parallel input is available for alternate and Pulse Width Modulation (PWM) control of the output. SPI programmable fault trip thresholds allow the device to be adjusted for optimal performance in the application. The 33982B is packaged in a power-enhanced 12 x 12 nonleaded PQFN package with exposed tabs.
