1 / 38 page  Document Number: MC33874 Rev. 9.0, 8/2008 Freescale Semiconductor Advance Information * This document contains certain information on a new product. Specifications and information herein are subject to change without notice. © Freescale Semiconductor, Inc., 2006-2008. All rights reserved. Quad High Side Switch (Quad 35m Ω) The 33874 is one in a family of devices designed for low-voltage automotive and industrial lighting and motor control applications. Its four low RDS(ON) MOSFETs (four 35mΩ) can control the high sides of four separate resistive or inductive loads. Programming, control, and diagnostics are accomplished using a 16-bit SPI interface. Additionally, each output has its own parallel input for pulse-width modulation (PWM) control if desired. The 33874 allows the user to program via the SPI the fault current trip levels and duration of acceptable lamp inrush or motor stall intervals. Such programmability allows tight control of fault currents and can protect wiring harnesses and circuit boards as well as loads. The 33874 is packaged in a power-enhanced 12x 12 nonleaded Power QFN package with exposed tabs. Features • Quad 35m Ω high side switches (at 25°C) • Operating voltage range of 6.0V to 27V with standby current < 5.0 μA • 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, under-voltage and over-voltage shutdown, fail-safe pin status, and program status • Analog current feedback with selectable ratio • Analog board temperature feedback • Enhanced -16V reverse polarity VPWR protection • Pb-free packaging designated by suffix code PNA Figure 1. 33874 Simplified Application Diagram HIGH SIDE SWITCH PNA SUFFIX (PB_FREE) 98ART10510D 24-PIN PQFN (12 x 12) 33874 ORDERING INFORMATION Device Temperature Range (TA) Package MC33874BPNA/R2 -40°C to 125°C 24 PQFN 33874 HS0 HS1 GND GND FSI CSNS HS2 HS3 MCU SCLK LOAD 0 LOAD 1 LOAD 2 LOAD 3 SCLK IN0 I/O IN1 IN2 IN3 I/O SI SO I/O I/O A/D VPWR VDD VDD VPWR WAKE I/O I/O VDD VDD CS CS RST SO VPWR SI FS TEMP A/D |
