3 Description

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-A peak source

and sink current along with low pull-up and pulldown

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.

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.

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.
