UCC27282 120-V Half-Bridge Driver

with Cross Conduction Protection and Low Switching Losses

1 Features

3 Description

The UCC27282 is a robust N-channel MOSFET

•

Drives two N-channel MOSFETs in high-side low-

side configuration

driver with a maximum switch node (HS) voltage

rating of 100 V. It allows for two N-channel MOSFETs

to be controlled in half-bridge or synchronous buck

configuration based topologies. Its 3.5-A peak sink

current and 2.5-A peak source current along with low

pull-up and pull-down resistance allows the

UCC27282 to drive large power MOSFETs with

minimum switching losses during the transition of the

MOSFET Miller plateau. Since the inputs are

independent of the supply voltage, UCC27282 can be

used in conjunction with both analog and digital

controllers.

16-ns typical propagation delay

12-ns rise, 10-ns fall time with 1.8-nF load

1-ns typical delay matching

Absolute Maximum Negative Voltage Handling on

HS (–14 V)

The input pins as well as the HS pin are able to

tolerate significant negative voltage, which improves

system robustness. Input interlock further improves

robustness and system reliability in high noise

applications. The enable and disable functionality

provides additional system flexibility by reducing

power consumption by the driver and responds to

fault events within the system. 5-V UVLO allows

systems to operate at lower bias voltages, which is

necessary in many high frequency applications and

improves system efficiency in certain operating

modes. Small propagation delay and delay matching

specifications minimize the dead-time requirement

which further improves efficiency.

3.5-A sink, 2.5-A Source output currents

Absolute maximum boot voltage 120 V

Low current (7-µA) consumption when disabled

Integrated bootstrap diode

Specified from –40°C to 140°C junction

temperature

2 Applications

•

Telecom and merchant power supplies

Motor drives and power tools

Auxiliary inverters

Under voltage lockout (UVLO) is provided for both the

high-side and low-side driver stages forcing the

outputs low if the VDD voltage is below the specified

threshold. An integrated bootstrap diode eliminates

the need for an external discrete diode in many

applications, which saves board space and reduces

system cost. UCC27282 is offered in a small package

enabling high density designs.

Half-bridge and full-bridge converters

Active-clamp forward converters

High voltage synchronous-buck converters

Class-D audio amplifiers
