Advance Information

Dual High-Side Switch 40 mΩ

The 33289 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.

33289

This device consists of two independent 40 mΩ R_DSONMOSFET

channels plus corresponding control circuitry in a surface mount

package. The 33289 can be interfaced directly to a microcontroller for

input control and monitoring of diagnostic output.

DUAL HIGH-SIDE SWITCH

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.
