HALF-BRIDGE DRIVER
Features
n Floating channel designed for bootstrap operation
Fully operational to +600V
Tolerant to negative transient voltage
dV/dt immune
n Gate drive supply range from 10 to 20V
n Undervoltage lockout for both channels
n CMOS Schmitt-triggered inputs with pull-down
n Matched propagation delay for both channels
n Internally set deadtime
n High side output in phase with input
Description
The IR2111 is a high voltage, high speed power
MOSFET and IGBT driver with dependent high and
low side referenced output channels designed for
half-bridge applications. Proprietary HVIC and latch
immune CMOS technologies enable ruggedized
monolithic construction. Logic input is compatible
with standard CMOS outputs. The output drivers
feature a high pulse current buffer stage designed
for minimum driver cross-conduction. Internal
deadtime is provided to avoid shoot-through in the
output half-bridge. The floating channel can be used
to drive an N-channel power MOSFET or IGBT in
the high side configuration which operates up to
600 volts.

Absolute Maximum Ratings
Absolute Maximum Ratings indicate sustained limits be yond which damage to the device ma y occur. All voltage parameters are
absolute voltages ref erenced to COM. The Thermal Resistance and P o wer Dissipation r atings are measured under board
mounted and still air conditions. Additional information is shown in Figures 7 through 10.
