IR2170, OVER CURRENT SENSOR

Packages IR2170(S) is the monolithic over current sensing IC de- signed for motor drive applications.

It senses the motor phase current through an external shunt resistor, de- tects overcurrent condition, and transfers the signal to the low side.

IR’s proprietary high voltage isolation tech-
