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.
