Dual High-Side Switch 40 mâ¦
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.
This device consists of two independent 40 m⦠RDSON MOSFET
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.
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.
