CURRENT LIMITING SIDE DRIVER
Features
Gate drive supply range from Undervoltage lockout Current detection limiting loop limit driven power transistor current Error lead indicates fault conditions programs shutdown time Output phase with input
Product Summary
VOFFSET IO+/VOUT VCSth ton/off (typ.) max.
Description
IR2121 high speed power MOSFET IGBT driver with over-current limiting protection circuitry. Latch immune CMOS technology enables ruggedized monolithic construction. Logic inputs compatible with standard CMOS LSTTL outputs. output driver features high pulse current buffer stage designed minimum cross-conduction. protection circuitry detects over-current driven power transistor limits gate drive voltage. Cycle-by-cycle shutdown programmed external capacitor which directly controls time interval between detection over-current limiting condition latched shutdown. output used drive N-channel power MOSFET IGBT side configuration.
