IR2170S Datasheet OVER CURRENT SENSOR

Manufacturer: International Rectifier (now Infineon)

Overview: Preliminary Data Sheet No. PD60186-C IR2170(S) OVER CURRENT SENSING.

General Description

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- nology is implemented to enable the high bandwidth sig- 8-Lead SOIC nal processing.

Key Features
