Product Summary

The IR2125 is a high voltage, high speed power MOSFET and IGBT driver with over-current limiting protection circuitry. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. The IR2125 features a high pulse current 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. The floating channel of the IR2125 can be used to drive an N-channel power MOSFET or IGBT in the high or low side configuration which operates up to 500 volts.

Parametrics

IR2125 absolute maximum ratings: (1)High Side Floating Supply Voltage:-0.3V to 525V; (2)High Side Floating Offset Voltage:VB - 25V to VB + 0.3V; (3)High Side Floating Output Voltage:VS - 0.3V to VB + 0.3V; (4)Logic Supply Voltage:-0.3V to 25V; (5)Logic Input Voltage:-0.3V to VCC + 0.3V; (6)Error Signal Voltage:-0.3V to VCC + 0.3V; (7)Current Sense Voltage:VS - 0.3V to VB + 0.3V; (8)Allowable Offset Supply Voltage Transient:50V/ns; (9)Package Power Dissipation @ TA ≤ +25℃:1.0W; (10)Thermal Resistance, Junction to Ambient:125℃/W; (11)Junction Temperature:150℃; (12)Storage T emperature:-55℃ to 150℃; (13)Lead Temperature (Soldering, 10 seconds):300℃.
