IR2172
Description
IR2172 is the monolithic current sensing IC designed for motor drive applications. It senses the motor phase current through an external shunt resistor, converts from analog to digital signal, and transfers the signal to the low side.
Key Features
- Floating channel up to +600V
- Linear current feedback through shunt resistor
- Direct digital PWM output for easy interface
- Low IQBS allows the boot strap power supply
- Independent fast overcurrent trip signal
- High mon mode noise immunity
- Input overvoltage protection for IGBT short circuit condition
