Single Intelligent High-current Self-protected Silicon High Side Switch (2.0m Ω) The 33982B is a self-protected silicon 2.0m Ω high side switch used to replace electromechanical relays, fuses, and discrete devices in power management applications. The 33982B is designed for harsh environments, and it 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. The 33982B is packaged in a power-enhanced 12 x 12 nonleaded PQFN package with exposed tabs. Features • Single 2.0m Ω max high side switch with parallel input or SPI control • 6.0V to 27V operating voltage with standby currents < 5.0 μA • Output current monitoring with two SPI-selectable current ratios • SPI control of over-current limit, over-current fault blanking time, output-OFF open load detection, output ON/OFF control, watchdog timeout, slew rates, and fault status reporting • SPI status reporting of over-current, open and shorted loads, over-temperature shutdown, under-voltage and over-voltage shutdown, fail-safe pin status, and program status • Enhanced -16V reverse polarity VPWR protection Figure 1. 33982B Simplified Application Diagram HIGH SIDE SWITCH 33982B ORDERING INFORMATION Device Temperature Range (TA) Package MC33982BPNA/R2 -40 °C to 125°C 16 PQFN SCALE 1:1 Bottom View PNA SUFFIX 98ARL10521D 16-PIN PQFN VDD I/O I/O SO SCLK CS SI I/O I/O A/D VPWR FS WAKE SI SCLK CS SO RST IN CSNS FSI GND HS GND LOAD 33982B MCU VDD VDD VDD VPWR GND PWR GND |
