Descriptions
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 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.
