3 Description

The UCC27282 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 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.

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.

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.
