H-Bridge Gate Driver IC

The 33883 is an H-bridge gate driver (also known as a full-bridge

pre-driver) IC with integrated charge pump and independent high and

low side gate driver channels. The gate driver channels are

independently controlled by four separate input pins, thus allowing

the device to be optionally configured as two independent high side

gate drivers and two independent low side gate drivers. The low side

channels are referenced to ground. The high side channels are

floating.

The gate driver outputs can source and sink up to 1.0 A peak

current pulses, permitting large gate-charge MOSFETs to be driven

and/or high pulse- width modulation (PWM) frequencies to be utilized.

A linear regulator is incorporated, providing a 15 V typical gate supply

to the low side gate drivers.

This device powered by SMARTMOS technology.
