Description
AI
The UCC27284 -Q1 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 UCC27284 -Q1 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 -Q1 can be used in conjunction with both analog and digital controllers. Two inputs, and therefore outputs, can be overlapped, if needed, in applications such as secondary side full-bridge synchronous rectification.
The input pins as well as the HS pin are able to tolerate significant negative voltage, which improves system robustness. 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.
Undervoltage 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-Q1 is offered in SOIC package for harsh system environments.
