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. IR's proprietary high voltage isolation technology is implemented to enable the high bandwidth signal processing. The output format of the IR2171 is discrete PWM at 40kHz to eliminate need for the A/D input interface. It allows direct interface to uP via simple counter based measurement. The independently powered output enables easy interface to the opto coupler device for galvanic isolation if needed.
