33289
Dual High-Side Switch
The 33289 is a dual high-side switch (DHSS) dedicated for use in
automotive and industrial applications. It is designed to drive typical inductive
loads such as solenoid valves.
This device consists of two independent 40 mΩ R_DSON 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 short
circuit, overvoltage, and undervoltage conditions, as well as an over-
temperature 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.
