Specifications and information herein are subject to change without notice. © Motorola, Inc. 2004 Document order number: MC33984 Rev 4.0, 09/2004 33984 Advance Information Simplified Application Diagram 33984 VDD VDD MCU VDD V PWR I/O FS I/O SO SCLK SI CS I/O I/O IN0 I/O IN1 A/D CSNS FSI HS0 GND GND GND VDD V PWR PWR GND WAKE SI SCLK SO RST CS LOAD HS1 LOAD Dual Intelligent High-Current Self-Protected Silicon High-Side Switch (4.0 m Ω) The 33984 is a dual self-protected 4.0 m Ω silicon switch used to replace electromechanical relays, fuses, and discrete devices in power management applications. The 33984 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 each output. SPI-programmable fault trip thresholds allow the device to be adjusted for optimal performance in the application. The 33984 is packaged in a power-enhanced 12 x 12 nonleaded PQFN package with exposed tabs. Features •Dual 4.0 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 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, Undervoltage and Overvoltage Shutdown, Fail-Safe Pin Status, and Program Status • Enhanced -16 V Reverse Polarity VPWR Protection DUAL HIGH-SIDE SWITCH 4.0 m Ω ORDERING INFORMATION Device Temperature Range (TA) Package MC33984PNA/R2 -40 °C to 125°C 16 PQFN 33984 Simplified Application Diagram SCALE 1:1 Bottom View PNA SUFFIX CASE 1402-02 16-TERMINAL PQFN (12 x 12) Freescale Semiconductor, Inc.
