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.
This device consists of two independent 40 mΩ 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.
FEATURES
• Designed to drive Automotive Inductive loads
• Operating Voltage Range from 6.0 V to 27 V
• Maximum Breakdown Voltage greater than 40 V
• 40 mΩ RDSON at 25°C
• Overtemperature Protection with Hysteresis
• Overcurrent protection
• Under Voltage Shutdown
• Over Voltage Shutdown
• Open Load Detection in Off-State
• Independent Diagnostic Output
• ESD Protection 2.0 kV
• Standby Current less than 5.0 µA at VBAT below 14 V
