UCC27288 2.5-A/3.5-A 120-V Half-Bridge Driver

with 8-V UVLO and External Bootstrap Diode

1 Features

3 Description

•

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

The UCC27288 is a robust N-channel MOSFET driver

side configuration

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

UCC27288 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, UCC27288 can be

used in conjunction with both analog and digital

controllers. Two inputs are completely independent of

each other and therefore provides added control

design flexibility.

16-ns typical propagation delay

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

1-ns typical delay matching

Configurable external 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. The inputs are completely

independent of each other. This allows for control

flexibility where two outputs can be overlapped by

overlapping inputs if needed. Small propagation delay

and delay matching specifications minimize the dead-

time requirement which improves system efficiency.

2 Applications

•

Solar power optimizer

Merchant network & server PSU

Merchant telecom rectifiers

DC input BLDC motor drive

Test & measurement equipment

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. No integrated bootstrap diode allows user

to use application-appropriate external bootstrap

diode. UCC27288 is offered in an SOIC8 package to

improve system robustness in harsh environments.
