HALF-BRIDGE DRIVER
General Description
The U3115S/U3116S Fully operated to +300V
is high voltage, high speed power MOSFET
and IGBT driver with dependent high and low
side referenced output channels.
The logic input is compatible with standard
CMOS or LSTTL output, down to 3.3V logic.
The output drivers feature a high pulse current
buffer stage designed for minimum driver
cross-conduction. The floating channel can be
used to drive an N-channel power MOSFET or
IGBT in the high side configuration which op-
erates up to 300 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.
