The 33982 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 33982 is packaged in a power-enhanced 12 x 12 PQFN package with exposed tabs. Features • Single 2.0 m Ω Max High-Side Switch with Parallel Input or SPI Control • 6.0 V to 27 V Operating Voltage with Standby Currents < 5.0 µA • Output Current Monitoring Output with Two SPI-Selectable Current Ratios • SPI Control of Overcurrent Limit, Overcurrent Fault Blanking Time, Output-OFF Open Load Detection, Output ON/OFF Control, Watchdog Timeout, Slew Rates, and Fault Status Reporting • SPI Status Reporting of Overcurrent, Open and Shorted Loads, Overtemperature Shutdown, Undervoltage and Overvoltage Shutdown, Fail-Safe Terminal Status, and Program Status • Enhanced 16 V Reverse Polarity VPWR Protection SINGLE HIGH-SIDE SWITCH 2.0 m Ω ORDERING INFORMATION Device Temperature Range (TA) Package MC33982PNA/R2 -40 °C to 125°C 16 PQFN PNA SUFFIX CASE 1402-02 16-TERMINAL PQFN 33982 Simplified Application Diagram Freescale Semiconductor, Inc.
