The Infineon Technologies IR22771SPBF is a single-phase current sensor interface IC for AC motor drive applications. It utilizes an external shunt resistor to sense current, converting the analog voltage into a time interval with high ripple rejection and small group delay. This IC supports a floating channel up to 1200V and operates with a supply voltage range of 8V to 20V.
Key electrical specifications include a sensing latency of less than 7.5 µsec at 20kHz and a maximum throughput of 40 ksample/sec, suitable for up to 20 kHz asymmetrical PWM modulation. It also provides a fast over-current detection signal for IGBT protection. The device is housed in a 16-SOIC package and is designed for surface mounting.
This current sensor IC is ideal for applications requiring precise current monitoring in AC motor control systems. Its high voltage capability and fast response time make it suitable for demanding industrial environments. The synchronous sampling measurement system ensures accurate readings, while the digital PWM output provides flexibility in system integration.
