IR2175 - Linear Current Sensor

Description

The IR2175 is a monolithic current sensing IC designed for motor drive applications.

It senses the motor phase current through an external shunt resistor, converts from analog to digital signal, and transfers the signal to the low side.

Features

  • Floating channel up to +600V.
  • Monolithic integration.
  • Linear current feedback through shunt resistor.
  • Direct digital PWM output for easy interface.
  • Low IQBS allows the boot strap power supply.
  • Independent fast overcurrent trip signal.
  • High common mode noise immunity.
  • Input overvoltage protection for IGBT short circuit condition.
  • Open Drain outputs.
  • Also available LEAD-FREE.
