IR2127C/IR2128C/IR21271C  
Description  
The IR2127/IR2128/IR21271(S) is a high voltage, high speed power MOSFET and IGBT driver. Proprietary HVIC  
and latch immune CMOS technologies enable ruggedized monolithic construction. The logic input is compatible  
with standard CMOS or LSTTL outputs, down to 3.3V. The protection circuity detects over-current in the driven  
power transistor and terminates the gate drive voltage. An open drain  
signal is provided to indicate that  
FAULT  
an over-current shutdown has occurred. The output driver features a high pulse current buffer stage designed for  
minimum cross-conduction. The floating channel can be used to drive an N-channel power MOSFET or IGBT in  
the high side or low side configuration which operates up to 600 volts.  
Absolute Maximum Ratings  
Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters  
are absolute voltages referenced to COM. The Thermal Resistance and Power Dissipation ratings are measured under  
board mounted and still air conditions.
