Advance Information
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.
