The IR2175S from Infineon Technologies is a monolithic current sensing IC specifically 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 features a floating channel up to +600V and provides a direct digital PWM output, eliminating the need for an A/D input interface.
Key electrical specifications include a supply voltage range of 9.5V to 20V and an input voltage range of ±260mV. The device boasts ±0.5% accuracy and a low quiescent current (IQBS) of 2mA, enabling efficient bootstrap power supply operation. It also includes an independent fast overcurrent trip signal with a delay of 2 µsec and a trip level of ±260mV, facilitating IGBT short circuit protection.
The IR2175S is housed in an 8-SOIC surface mount package, measuring 0.154 inches (3.90mm) in width. It operates within an ambient temperature range of -40°C to 125°C. The open-drain outputs allow for easy interfacing with voltages from 3.3V to 15V. This IC is suitable for applications requiring precise current monitoring and protection in power systems.
