www.DataSheet4U.com Freescale Semiconductor Advance Information Document Number: MC33288 Rev 6.0, 5/2006 Solid State Relay for Automotive Flasher Applications This device is a Dual High-Side Power Switch dedicated for automotive flasher applications. In comparison with mechanical solutions, this device offers higher reliability as well as protection and diagnostic features. The device consists of two 25 mΩ Rdson fully protected high side switches, in a surface mount power package. It interfaces directly with a microcontroller and includes a current recopy function in order to allow the detection of a failed lamp in the application. Features Junction Temperature Range from -40°C to 150°C Operating Voltage Range from 8.0 V to 35 V Maximum Breakdown Voltage greater than 40 V 25 mΩ RDS(ON) per Channel at 25°C 8.0 Amps Nominal Current per Channel 1.2 W Warning Lamp Driver Overtemperature Protection with Hysteresis Open Load Detection in ON State Current Recopy to Monitor Lamp Output Current 33288 SOLID STATE RELAY DH SUFFIX 98ASH70273A 20-LEAD HSOP ORDERING INFORMATION Device MC33288DDH/R2 Temperature Range (TA) -40°C to 125°C Package 20 HSOP Standby Current < 10 µA at VBAT < 14 V Simplified Application Diagram 5.0 V VPWR 33288 VBAT ST OUT-1 IN-1 WLP IN-2 Cur R OUT-2 GND 21 W 21 W 5W 21 W 5W MCU 1.2 W 21 W 21 W 5W 21 W 5W Figure 1. 33288 Simplified Internal Block Diagram * This document contains certain information on a new product.
