Description
The IR2125Z is a high voltage, high speed power
MOSFET and IGBT driver with over-current limiting
protection circuitry . Proprietary GVIC and latch immune
CMOS technologies enable ruggedized minilithic
consturction. Logic inputs are compatible with standard
CMOS or LSTTL outputs. the ouput driver 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. 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 or IGBT in the high
or low side configuration which operates up to 400 volts.
Absolute Maximum Ratings
Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All voltage
parameters are absolute voltages referenced to COM. The Thermal Resistance and Power Dissipation ratings
are measured under board mounted and still air conditions.
