The IR2277SPBF from Vishay Dale is a high voltage, high speed single-phase 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 digital PWM signal and a ratiometric analog voltage proportional to the measured current, suitable for DSP A/D interfaces.
Key features include a floating channel capable of up to 600V for the IR2177 variant, high PWM noise rejection, and fast over-current detection for IGBT protection. The IC supports synchronous sampling and offers low sensing latency of less than 7.5 µsec at 20kHz, with a maximum throughput of 40 ksample/sec. It is designed for bootstrap power supplies and operates within a specified input voltage range.
This device is typically housed in a surface-mount package, facilitating integration into compact electronic designs. Its robust design makes it suitable for demanding AC motor control systems where precise current monitoring and protection are essential.
