open-in-new Find other Half-bridge drivers

Description

The UCC27284 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 3.5-A peak sink current and 2.5-A peak source current along with low pull-up and pull-down resistance allows the UCC27284 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, UCC27284 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. The enable and disable functionality provides additional system flexibility by reducing the gate driver power consumption and quickly 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. UCC27284 is offered in a small package enabling high density designs.
