IR2170
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.
Key Features
- Floating channel up to +600V
- Overcurrent sensing through shunt resistor
- Low IQBS allows the boot strap power supply
- Independent fast 1µsec overcurrent trip signal
- High mon mode noise immunity
- Input overvoltage protection for IGBT short circuit condition
