1 / 25 page  Document Number: MC33880 Rev. 5.0, 6/2007 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. Configurable Octal Serial Switch with Serial Peripheral Interface I/O The 33880 device is an eight-output hardware-configurable high- side/low-side switch with 8-bit serial input control. Two of the outputs can be controlled directly via microcontroller for Pulse Width Modulation (PWM) applications. The 33880 controls various inductive or incandescent loads by directly interfacing with a microcontroller. The circuit's innovative monitoring and protection features include very low standby currents, “cascadable” fault reporting, internal 40 V output clamping for low-side configurations, internal -20 V output clamping for high-side configurations, output-specific diagnostics, and independent shutdown of outputs. Features • Designed to Operate 5.5 V < VPWR < 24.5 V • 8-Bit SPI for Control and Fault Reporting, 3.3 V/5.0 V Compatible • Outputs Are Current Limited (0.8 A to 2.0 A) to Drive Incandescent Lamps • Output Voltage Clamp Is +45 V (Typical) (Low-Side Drive) and - 20 V (Typical) (High-Side Drive) During Inductive Switching • Internal Reverse Battery Protection on VPWR • Loss of Ground or Supply Will Not Energize Loads or Damage IC • Maximum 5.0 µA I PWR Standby Current at 13 V VPWR up to 95°C •RDS(ON) of 0.55 Ω at 25°C Typical • Short Circuit Detect and Current Limit with Automatic Retry • Independent Overtemperature Protection • 32-Pin SOICW Has Pins 8, 9, 24, and 25 Grounded for Thermal Performance • Pb-Free Packaging Designated by Suffix Code EG and EW Figure 1. 33880 Simplified Application Diagram HIGH/LOW-SIDE SWITCH DW SUFFIX EG SUFFIX (PB-FREE) 98ASB42345B 28-PIN SOICW 33880 ORDERING INFORMATION Device Temperature Range (TA) Package MC33880DW/R2 -40 °C to 125°C 28 SOICW MCZ33880EG/R2 MC33880DWB/R2 32 SOICW MCZ33880EW/R2 DWB SUFFIX EW SUFFIX (PB-FREE) 98ARH99137A 32-PIN SOICW All Output Switches are High- or Low-Side Configurable V PWR 33880 SPI I/O PWM MCU MOT High-Side H-Bridge Low-Side 5.0 V 5.0 V V S D1 D2 D4 D5 D6 D7 S8 D3 EN VDD VPWR GND CS SCLK DI DO IN5 IN6 S1 S2 S4 D8 S5 S6 S7 S3 |
