DUAL LOW SIDE DRIVER
Features
Gate drive supply range from 6 to 20V
CMOS Schmitt-triggered inputs with pull-up
Matched propagation delay for both channels
Outputs out of phase with inputs
Description
The IR1210 is a low voltage, high speed power
MOSFET and IGBT driver. Proprietary latch immune
CMOS technologies enable ruggedized monolithic
construction. Logic inputs are compatible with stan-
dard CMOS or LSTTL outputs. The output drivers
feature a high pulse current buffer stage designed
for minimum driver cross-conduction. Propagation
delays between two channels are matched.

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage param-
eters are absolute voltages referenced to GND. The thermal resistance and power dissipation ratings are measured
under board mounted and still air conditions.
