UCC27289 2.5-A/3.5-A 120-V Half-Bridge Driver

with 8-V UVLO and Negative Voltage Handling

1 Features

3 Description

•

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

side configuration

The UCC27289 is a robust N-channel MOSFET 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

UCC27289 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, UCC27289 can be

used in conjunction with both analog and digital

controllers. Two inputs are completely independent of

each other and thus two outputs can be overlapped

by overlapping inputs, if needed. The enable and

disable functionality provides additional system

flexibility by reducing power consumption by the driver

and responds to fault events within the system.

Enable/disable functionality in DRC package

Low current (7-μA) consumption when disabled

16-ns typical propagation delay

12-ns rise, 10-ns fall time with 1800-pF load

(typical)

•

1-ns typical delay matching

Integrated 100V bootstrap diode

8-V typical undervoltage lockout

Absolute maximum negative voltage handling on

inputs (–5 V)

Absolute maximum negative voltage handling on

HS (–14 V)

3.5-A sink, 2.5-A Source output currents

Absolute maximum boot voltage 120 V

Inputs are independent of each other and VDD

Under voltage lockout for both channels

Specified from –40°C to 140°C junction

temperature

•

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

tolerate significant negative voltage, which improves

system robustness. Small propagation delay and

delay matching specifications minimize the dead-time

requirement which improves system efficiency.

2 Applications

•

Merchant network & server PSU

Merchant telecom rectifiers

DC input BLDC motor drive

Solar micro 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. UCC27289 is offered in multiple

packages to accommodate system requirements such

as robustness in harsh environments and density in

compact applications.
