1 / 27 page  Document Number: MC33882 Rev. 5.0, 10/2006 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. All rights reserved. Six-Output Low-Side Switch with SPI and Parallel Input Control The 33882 is a smart six-output low-side switch able to control system loads up to 1.0 A. The six outputs can be controlled via both serial peripheral interface (SPI) and parallel input control, making the device attractive for fault-tolerant system applications. There are two additional 30 mA low-side switches with SPI diagnostic reporting (with parallel input control only). The 33882 is designed to interface directly with industry-standard microcontrollers via SPI to control both inductive and incandescent loads. Outputs are configured as open-drain power MOSFETs incorporating internal dynamic clamping and current limiting. The device has multiple monitoring and protection features, including low standby current, fault status reporting, internal 52 V clamp on each output, output-specific diagnostics, and protective shutdown. In addition, it has a mode select pin affording a dual means of input control. Features • Outputs Clamped for Switching Inductive Loads • Very Low Operational Bias Currents (< 2.0 mA) • CMOS Input Logic Compatible with 5.0 V Logic Levels • Load Dump Robust (60 V Transient at VPWR on OUT0–OUT5) • Daisy Chain Operation of Multiple Devices Possible • Switch Outputs Can Be Paralleled for Higher Currents •RDS(ON) of 0.4 Ω per Output (25°C) at 13 V VPWR • SPI Operation Guaranteed to 2.0 MHz • Pb-Free Packaging Designated by Suffix Codes VW and EP Figure 1. 33882 Simplified Application Diagram SIX-OUTPUT LOW-SIDE SWITCH DH SUFFIX VW SUFFIX (PB-FREE) 98ASH70329A 30-PIN HSOP 33882 ORDERING INFORMATION Device Temperature Range (TA) Package MC33882DH/R2 -40°C to 125°C 30 HSOP MC33882VW/R2 MC33882FC/R2 32 QFN MC33882EP/R2 FC SUFFIX EP SUFFIX (PB-FREE) 98ARH99032A 32-PIN QFN MCU 33882 VDD VPWR Optional Parallel Control of Outputs 0 through 7 Optional Control of Paired Outputs SCLK SI SO VDD VPWR IN0 IN1 IN2 IN3 IN4 IN5 GND OUT0 OUT1 OUT2 OUT3 OUT4 OUT5 IN0 & IN1 IN2 & IN3 IN4 & IN5 MODE OUT6 OUT7 IN6 IN7 CS High-Power Outputs Low-Power LED Outputs |
