The Texas Instruments UCC27201A-Q1 is a high-frequency N-channel MOSFET
driver that includes a 120V bootstrap diode and high-side / low-side driver
with independent inputs for maximum control flexibility. This allows for
N-Channel MOSFET control in half-bridge, full-bridge, two-switch forward and
active clamp forward converters.
The low-side and the high-side gate drivers are independently controlled and
matched to 1-ns between the turn-on and turn-off of each other. The
UCC27201A-Q1 is based on the popular UCC27200 and UCC27201 drivers, but with
enhancements. In order to improve performance in noisy power supply
environments the UCC27201A-Q1 has the ability to withstand a maximum of -18V
on its HS pin.
An on-chip bootstrap diode eliminates the external discrete diodes.
Under-voltage lockout is provided for both the high-side and the low-side
drivers forcing the outputs low if the drive voltage is below the specified
threshold. The UCC27201A-Q1 has TTL-compatible thresholds and is offered in
an 8-pin SOIC with a thermal pad.
