What are the key features of UCC23511BDWY?
- 5.7 kVRMS reinforced isolation voltage in a 6-pin SOP package, enabling direct optocoupler replacement without PCB redesign
- 1 A peak output drive current with opto-compatible input thresholds, supporting IGBTs and SiC MOSFETs up to high switching frequencies
- Wide VCC2 supply range and propagation delay matched for high-side and low-side gate drive in half-bridge and full-bridge topologies
What is UCC23511BDWY used for?
The UCC23511BDWY is designed for isolated gate driving of IGBTs and SiC MOSFETs in industrial motor drives, solar inverters, and on-board EV chargers where reinforced 5.7 kVRMS isolation is required between the control logic and high-voltage power stage. Its opto-compatible input makes it a drop-in replacement for traditional photocoupler gate drivers such as the TLP350 or HCPL-314J, reducing solution size and improving switching speed. It is also used in uninterruptible power supplies and industrial power factor correction stages where reliable isolation and fast turn-on/turn-off transitions at 1 A drive current are critical.

Frequently Asked Questions
What isolation voltage does UCC23511BDWY provide, and does it meet reinforced insulation requirements for 600 V bus designs?
The UCC23511BDWY is rated at 5.7 kVRMS working isolation, which satisfies reinforced insulation requirements per IEC 60747-17 for systems operating on 600 V DC buses. This margin is sufficient for industrial inverters and motor drives that require safety-rated isolation between the 3.3 V or 5 V control side and the high-voltage power stage, avoiding the need for external isolation transformers or additional clearance on the PCB.
Can UCC23511BDWY directly replace an optocoupler gate driver like TLP350 in a PCB without layout changes?
Yes. The UCC23511BDWY uses opto-compatible input thresholds with a 6-pin SOP package footprint that matches common optocoupler gate drivers. Its input forward current range and logic-high threshold are designed to accept the same LED drive currents used by TLP350-class devices. Swapping the part requires only a decoupling capacitor on VCC2 and verification of the VOUT rail; no PCB trace rerouting is typically needed.
What peak gate current does UCC23511BDWY deliver, and is it sufficient to drive a 650 V SiC MOSFET at 100 kHz?
The UCC23511BDWY delivers 1 A peak source and sink current into the gate. For a 650 V SiC MOSFET with 10 nC total gate charge, 1 A of drive current charges the gate in approximately 10 ns, enabling clean switching transitions at 100 kHz and beyond. This drive strength avoids excessive switching losses and reduces EMI by ensuring the MOSFET transitions fully within each switching period.
