Description for the UCC27284-Q1

The UCC27284-Q1 is a robust N-channel MOSFET driver with amaximum switch node (HS) voltage rating of 100 V. It allows for two N-channel MOSFETs to becontrolled in half-bridge or synchronous buck configuration based topologies. Its 3.5-A peak sinkcurrent and 2.5-A peak source current along with low pull-up and pull-down resistance allows theUCC27284-Q1 to drive large power MOSFETs with minimum switchinglosses during the transition of the MOSFET Miller plateau. Since the inputs are independent of thesupply voltage, UCC27284-Q1 can be used in conjunction with bothanalog and digital controllers.

The input pins as well as the HS pin are able to tolerate significant negative voltage,which improves system robustness. The enable and disable functionality provides additional systemflexibility by reducing the gate driver power consumption and quickly responds to fault eventswithin the system. 5-V UVLO allows systems to operate at lower bias voltages, which is necessary inmany high frequency applications and improves system efficiency in certain operating modes. Smallpropagation delay and delay matching specifications minimize the dead-time requirement whichfurther improves efficiency.

Under voltage lockout (UVLO) is provided for both the high-side and low-side driverstages forcing the outputs low if the VDD voltage is below the specified threshold. An integratedbootstrap diode eliminates the need for an external discrete diode in many applications, whichsaves board space and reduces system cost. UCC27284-Q1 is offered ina small package enabling high density designs.
