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 terminals, 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.
