MC33289 : DHSS - Dual High Side Switch for Inductive Loads

Designed to Drive Automotive Inductive Loads

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.
