75V Low-side Intelligent Power Switches for Harsh 24V Automotive Environments

International Rectifier, IR has introduced two power switches for harsh 24V automotive environments, including truck junction box applications. The AUIPS2051L and AUIPS2052G feature a 70V active clamp and provide a comprehensive set of protection features. The devices shut down in the event of over-temperature or over-current conditions, restarting once the input is turned off and turned on again, and provide the diagnostic information via a serial resistor connected to the input pin. Furthermore, the AUIPS205x family is designed using IR's 75V technology making them well suited to any 24V automotive loads such as solenoids or as electromechanical relay replacements.

The AUIPS2052G is a dual channel device while the AUIPS2051L is a single channel device.
The turn-on and turn-off time are optimized to minimize noise in EMI sensitive automotive applications. Both devices also provide ESD protection and low current and logic level input.

The devices are qualified according to AEC-Q100 standards, feature an environmentally friendly, lead-free and RoHS compliant bill of materials, and are part of IR's automotive quality initiative targeting zero defects. Pricing for the AUIPS2051L begins at US $0.55 each in 100,000-unit quantities and US $0.75 each in 100,000-unit quantities for the AUIPS2052G. Production orders are available immediately. Prices are subject to change.
