IR2171 - LINEAR CURRENT SENSOR

Description

IR2171 is the linear current sensing IC designed for motor drive applications.

It senses the motor phase current through an extenal 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.
  • High Common Mode Noise Immunity.
  • Input overvoltage Protection for IGBT short circuit condition.
  • Open Drain output Product Summary.
