IR2121 - International Rectifier

IR2121 CURRENT LIMITING LOW SIDE DRIVER

VOFFSET IO+/VOUT VCSth ton/off (typ.) 5V max. 1A / 2A 12 - 18V 230 mV 150 & 150 ns The IR2121 is a high speed power MOSFET and Package IGBT driver with over-current limiting protection cir- cuitry. Latch immune CMOS technology enables rug- gedized monolithic construction. Logic inputs are compatible with standard CMOS or LSTTL outputs, down to 2.5V l.
