33984 Datasheet | NXP Semiconductors

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 mm x 12 mm nonleaded PQFN package with exposed tabs. Features - Dual 4.0 m max. high-side switch with parallel input or SPI control - 6.0 V to 27 V operating voltage with standby currents < 5.0 A - 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 HIGH-SIDE SWITCH BOTTOM VIEW FK SUFFIX 98ARL10521D 98ASA00815D 16-PIN PQFN Applications - DC motor or solenoid - Resistive or inductive loads - Low-voltage lighting I/O I/O SO SCLK MCU CS SI I/O I/O I/O A/D VPWR VPWR FS WAKE SI SCLK CS SO RST INO IN1 CSNS FSI HS1 HS0 GND LOAD LOAD Figure 1. 33984 simplified application diagram © 2023 NXP B.V.
