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 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.
Features
• V_CC operating voltage range from 5.5 V up to 55 V
• V_CC2 operating voltage range from 5.5 V up to 28 V
• CMOS/LSTTL compatible I/O
• 1.0 A peak gate driver current
• Built-in high side charge pump
• Under-voltage lockout (UVLO)
• Over-voltage lockout (OVLO)
• Global enable with <10 A Sleep mode
• Supports PWM up to 100 kHz
