IR Introduces Intelligent Power Switch with High Frequency PWM Capability

International Rectifier (IR)® introduced the AUIPS7221R 65V high-side intelligent power switch with fully integrated bootstrap function for fast actuator applications including fuel magnetic injectors and braking valves.

Housed in a small form factor, the AUIPS7221R delivers high frequency of 100 kHz and high current capability up to 25A making it well suited to harsh 12 or 24V environments. Additionally, the device integrates a charge pump for full dc operation and features over-current and over-temperature shutdown to help assure safe operation and protection under repetitive short circuit conditions.

"Designing high current and high frequency protected switches using the AUIPS7221R integrated solution drastically reduces PCB constraints and significantly increases the performance of the entire system. Moreover, fuel injection is more efficient, reducing both consumption and contamination," said David Jacquinod, Product Marketing Manager, IR Automotive Business Unit.

The AUIPS7221R also features diagnostic function and very low current consumption in sleep mode. The device is qualified according to AEC-Q100 standards, features an environmentally friendly, lead-free and RoHS compliant bill of materials, and is part of IR’s automotive quality initiative targeting zero defects.

Available in a DPAK package, pricing for the AUIPS7221R begins at US $1.23 in 100,000-unit quantities. Production orders are available immediately. The automotive-qualified device is lead-free and RoHS compliant.
