The IR2277SPBF from Infineon Technologies is a high voltage, high speed current sensor interface IC designed for AC motor drive applications. It utilizes an external shunt resistor to sense current, converting the analog voltage into a time interval with excellent ripple rejection. The output is provided as both a PWM signal and an analog voltage proportional to the measured current.
Key electrical specifications include an input voltage range of ±250mV and a bootstrap supply range of 8V to 20V. The device boasts a low sensing latency of less than 7.5 µsec at 20kHz and a maximum throughput of 40 ksample/sec, making it suitable for up to 20 kHz asymmetrical PWM modulation. It also features a fast over-current detection signal for IGBT protection.
This IC operates within a temperature range of -40°C to 125°C and is housed in a 16-SOIC surface mount package. Its accuracy is rated at ±0.2%, ensuring reliable current measurements for demanding motor control systems.
