| MOTOROLA Order Number: MC33289/D Rev. 2.3, 06/2001 Semiconductor Technical Data Advance Information MC33289 AUTOMOTIVE DUAL HIGH SIDE SWITCH SEMICONDUCTOR TECHNICAL DATA Automotive Dual High Side Switch The MC33289DW is a Dual High Side Switch (DHSS) dedicated for use in automotive applications. It is designed to drive typical inductive loads such as solenoid valves. This device consists of two independent 40mOhm Rdson MOSFET channels plus corresponding control circuitry in a surface mount package. The MC33289DW can be interfaced directly to a microcontroller for input control and monitoring of diagnostic output. Each switch offers independent protection and diagnosis during overcurrent, overvoltage, and undervoltage conditions, as well as an overtemperature shutdown feature. A logic low on the Open Load Detect Enable pin (OLDE) minimizes bias current drain by disabling the open load circuitry current source. The device also has a very low quiescent current in standby mode. * Designed to drive Automotive Inductive loads * Junction Temperature Range from -40C to 150C * Operating Voltage Range from 6V to 27V * Maximum Breakdown Voltage greater than 40V * Surface Mount Package * 40m Rdson at 25C * Overtemperature Protection with Hysteresis * Overcurrent protection * Under Voltage Shutdown * Over Voltage Shutdown * Open Load Detection in Off-State * Independent Diagnostic Output * ESD Protection 2kV * Standby Current less than 5A at Vbat below 14V DW SUFFIX SO20WB Package CASE 751D-05 PIN ASSIGNMENT Vbat Vbat Out1 Out1 Vbat Vbat NC In 1 St1 OLDE 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 V bat V bat Out2 Out2 V bat V bat NC In 2 St2 Gnd ORDERING INFORMATION Device PC33289DW Operating Temperature Range TA=-40 to +125C Package SO20 Simplified Application Schematic 5V 5V 5V 10k 10k V BAT + - ST1 ST2 IN1 IN2 OLDE LOAD2 OUT1 MCU MC33289 OUT2 LOAD1 This document contains information on a new product.

MC33289 PINS FUNCTION DESCRIPTION Pin No. Name/Function Description 1, 2, 5, 6, 15, 16, 19, 20 Vbat Supply Voltage These are the power supply pins of the device. These pins are directly connected with the lead frame of the package and are tied to the drain of the switching MOSFET. These pins can be directly connected to the battery voltage. In addition to their supply function, these pins participate to the thermal behaviour of the device in conducting the heat from the switching MOSFET to the printed circuit board. Pins 3 and 4 are the output 1 terminals. Pins 17 and 18 are the output 2 terminals. They are directly connected to the source of the power MOSFET. These pins are used by the control circuitry to sense the device output voltage. The Rdson is 40m max per output at 25C and will increase to a maximum of 75m at 150C junction temperature. These are the device input pins which directly control their associated outputs. The levels are CMOS compatible. When the input is a logic low, the associated output MOSFET is in the off state. When input is high, the MOSFET is turned on and the load is activated. When both inputs are low, the device is in standby mode and its supply current is reduced. Each input pin has an internal active pull down, so that it will not float if disconnected. These pins are the channel 1 and channel 2 fault detection flags. Their internal structure is an open drain architecture with an internal clamp at 6V. An external pull up resistor connected to Vdd (5V) is needed. This is an active loaw output. If the device is in its normal condition the status lines will be high. If open load or other fault occurs, the associated channel' status flag will be pulled low. See Functional Truth Table. This pin is a digital input which enables the open load current diagnostic circuitry. When OLDE is a logic low, the open load circuitry is not powered and the device's bias current draw is at a minimum. If OLDE is a logic high, the open load circuitry is functional at the price of a higher bias current draw. OLDE pin has a pull down resistor. This is the Gnd pin of the device. 3, 4, 18, 17 OUT1 OUTPUT Channel 1 OUT 2 OUTPUT Channel 2 IN 1 INPUT Channel 1 IN 2 INPUT Channel 2 8, 13 9, 12 St1 Status for Channel 1 St2 Status for Channel 2 10 OLDE Open Load Detection Enable 11 GND GROUND Automotive Dual High Side Switch 2 MC33289 Block Diagram And Typical Application Battery V bat Vbat Vbat Vbat OUT2 OUT2 Load 2 5V Vbat Vbat Vbat V bat Thermal Sensor Over Temp Status 2 Charge Pump CHANNEL 2 OUT1 OUT1 Input Trigger Status pull-up resistors 10K 10K IN2 MCU IN1 OLDE Status 1 U.V.& O.V.
