MC33982CHFK

Freescale Semiconductor Document Number: MC33982 Rev. 18.0, 9/2014 Advance Information Single Intelligent High-current Self- protected High-side Switch 33982 (2.0 mOhm) The 33982 is a self-protected silicon 2.0 mOhm high-side switch used to replace HIGH-SIDE SWITCH electromechanical relays, fuses, and discrete devices in power management applications. The 33982 is designed for harsh environments and includes self- recovery 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.
