Descriptions

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 band-

width signal processing. The output format 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 pow-

ered output enables easy interface to the opto cou-

pler device for galvanic isolation if needed.

IR2171 is the linear current sensing IC designed for
