The Infineon Technologies IR2172SPBF is a monolithic current sensing integrated circuit designed for motor drive applications. It accurately senses motor phase current through an external shunt resistor, converting the analog signal to a digital PWM output for easy interface. This IC supports floating channels up to +600V and operates with an input voltage range of 9.5V to 20V.
Key electrical specifications include a typical quiescent current of 1mA, a typical frequency of 40kHz, and an overcurrent trip time of 1.5µs. The device offers an overcurrent trip level of ±260mV (typical) and a gain temperature drift of 20ppm/°C (typical). It operates within a temperature range of -40°C to 125°C.
The IR2172SPBF is housed in an 8-SOIC surface mount package. Its design incorporates high voltage isolation technology for high bandwidth signal processing and provides an independent fast overcurrent trip signal for IGBT short circuit protection. The open-drain outputs allow for easy interfacing from 3.3V to 15V.
