Data Sheet No. PD60017 Rev.Q IR2125(S) & (PbF) CURRENT LIMITING SINGLE CHANNEL DRIVER Features Floating channel designed for bootstrap operation Fully operational to +500V Tolerant to negative transient voltage dV/dt immune Gate drive supply range from 12 to 18V Undervoltage lockout Current detection and limiting loop to limit driven power transistor current Error lead indicates fault conditions and programs shutdown time Output in phase with input 2.5V, 5V and 15V input logic compatible Also available LEAD-Free Product Summary VOFFSET 500V max. IO+/- 1A / 2A VOUT 12 - 18V VCSth 230 mV ton/off (typ.) 150 & 150 ns Packages Description The IR2125(S) is a high voltage, high speed power MOSFET and IGBT driver with over-current limiting protection circuitry. Proprietary HVIC and latch im- mune CMOS technologies enable ruggedized mono- lithic construction. Logic inputs are compatible with standard CMOS or LSTTL outputs, down to 2.5V logic. The output driver features a high pulse current 8-Lead PDIP 16-Lead SOIC (Wide Body) buffer stage designed for minimum driver cross-conduction. The protection circuitry detects over-current in the driven power transistor and limits the gate drive voltage. Cycle by cycle shutdown is programmed by an external capacitor which directly controls the time interval between detection of the over-current limiting conditions and latched shutdown. The floating channel can be used to drive an N-channel power MOSFET o...
