Data Sheet No. PD60018-M IR2121 & (PbF) CURRENT LIMITING LOW SIDE DRIVER Features • Gate drive supply range from 12 to 18V • Undervoltage lockout • Current detection and limiting loop to limit driven Product Summary VOFFSET 5V max. power transistor current IO+/- 1A / 2A shutdown time VOUT 12 - 18V VCSth 230 mV ton/off (typ.) 150 & 150 ns • Error lead indicates fault conditions and programs • Output in phase with input • 2.5V, 5V and 15V input logic compatible • Also available LEAD-FREE Description The IR2121 is a high speed power MOSFET and Package IGBT driver with over-current limiting protection circuitry. Latch immune CMOS technology enables ruggedized monolithic construction. Logic inputs are compatible with standard CMOS or LSTTL outputs, down to 2.5V logic. The output driver features a high pulse current buffer stage designed for minimum cross-conduction. The protection circuitry detects over-current in the driven power transistor and limits the gate drive voltage. Cycle-by-cycle shut8-Lead PDIP down is programmed by an external capacitor which directly controls the time interval between detection of the over-current limiting condition and latched shutdown. The output can be used to drive an N-channel power MOSFET or IGBT in the low side configuration. Typical Connection (Refer to Lead Assignments for correct pin configuration).
