High Voltage IC Half Bridge Gate Driver
The HIP5500, a high voltage integrated circuit (HVIC) half-
bridge gate driver for standard power MOSFETs, IGBTs,
and the new Intersil Buffered MOSFET (RFV10N50BE), can
be employed in a wide variety of switching regulator circuits.
The HIP5500 combines the functionality and flexibility of a
PWM IC with the convenience of a high voltage half-bridge
driver optimized for power supply inverters. It can be used
either open-loop or in closed-loop fashion using the SS input
for controlling the output waveform duty-cycle.
The HIP5500 incorporates a precision oscillator, adjustable
using an external resistor and capacitor. The resistor sets
the capacitor charging current and the capacitor sets the
integration time of a triangle wave. Another resistor
connected to the DIS pin adjusts the dead-time and can be
tailored to the application. The oscillator switches at twice
the output waveform fundamental frequency. The result is an
output waveform whose positive and negative half-cycles
are near perfect balance (volt-second equalization).
Short-Detect (SD) and Soft-Start (SS) inputs provide
alternative means for limiting and regulating respectively the
half-bridge output voltage. A capacitor on the SS input will
begin charging up once the EN input is made high and
causes the duty cycle of each half-cycle to “ramp” the duty
cycle of the output waveform.
The SD input can sense a signal proportional to current,
providing a means of shortening the conduction periods
below that imposed by the SS input.
Other circuits within the HIP5500 “match” upper and lower
turn-on and turn-off propagation times in order to minimize
flux imbalances when driving output transformer loads.
