1 / 40 page  Document Number: MC33888 Rev. 6.0, 2/2007 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., 2007. All rights reserved. Quad High-Side and Octal Low-Side Switch for Automotive The 33888 is a single-package combination of a power die with four discrete high-side MOSFETs (two 10 m Ω and two 40 mΩ) and an integrated IC control die consisting of eight low-side drivers (600 m Ω each) with appropriate control, protection, and diagnostic features. Programming, control, and diagnostics are accomplished using a 16-bit SPI interface. Additionally, each high-side output has its own parallel input for pulse-width modulation (PWM) control if desired. The low sides share a single configurable direct input. Features •Dual 10 m Ω High Side, Dual 40 mΩ High Side, Octal 600 mΩ Low Side • Full Operating Voltage of 6.0 V to 27 V • SPI Control of High-Side Overcurrent Limit, High-Side Current Sense, Output OFF Open Load Detection, Output ON/OFF Control, Watchdog Timeout • SPI Reporting of Program Status and Fault • High-Side Analog Current Feedback with Selectable Ratio • Enhanced 16 V Reverse Polarity VPWR Protection Figure 1. 33888 Simplified Application Diagram HIGH-SIDE/LOW-SIDE SWITCH PNB SUFFIX 98ARL10544D 36-PIN PQFN 33888 33888A ORDERING INFORMATION Device Temperature Range (TA) Package MC33888APNB/R2 -40°C to 125°C 36 PQFN MC33888FB/R2 64 PQFP FB SUFFIX 98ARH99043A 64-PIN PQFP Bottom View Top View +5.0 V +5.0 V FSI FS MCU A/D A/D CSNS0-1 CSNS2-3 WDIN SPI IHS0:IHS3 ILS RST VDD 4 4 GND VPWR LS4:LS11 HS3 HS2 HS1 HS0 Loads 8 x Relay or LED 33888 VPWR |
