The UCC27201A-Q1 high frequency N-Channel MOSFET driver includes a 120-V 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 offer some enhancements. In order to improve performance
in noisy power supply environments the UCC27201A-Q1 has the ability to withstand a maximum of -18 V
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 a 10-Pin VSON and an
8-pin SOIC with a thermal pad.
For all available packages, see the orderable addendum at the
