Advance Information
Automotive Dual
High Side Driver
This device is a dual high side power switch dedicated for automoive
applications. In comparison with mechanical relays, this device offers higher
reliability as well as protection and diagnostic features.
The device consists of two independent 35mΩ Rdson switches in a
surface mount package. It can be directly interfaced with a microcontroller
for control and diagnostic functions. The device is fully protected against
overcurrents, short-circuits and incorporates an overtemperature shutdown.
It can be directly and continuously supplied by the battery and offers a very
low quiescent current in standby mode.
• Designed for Automotive Applications
• Junction Temperature Range from -40°C to 150°C
• Operating Voltage Range from 8V to 40V
• Maximum Breakdown Voltage greater than 40V
• Surface Mount Package
• 35mΩ Rdson at 25°C
• Overtemperature Protection with Hysteresis
• Under Voltage Shutdown
• Reverse Battery protected
• Open Load Detection in On-State
• Diagnostic Output
• ESD Protection 2kV
• Current Limitation at 30A
• Loss of ground protected
• Standby Current less than 10µA at Vbat = 14V
