Overview
The UCC20520DW is a dual-channel reinforced isolated gate driver featuring a single input configuration. It delivers a 4-A source and 6-A sink peak output current, supporting power MOSFETs and IGBTs. The device operates with an output supply voltage range of 9.2 V to 25 V. Key electrical specifications include a typical rise time of 6 ns and fall time of 7 ns, with a maximum propagation delay of 30 ns. It functions within an operating temperature range of -40°C to +125°C and provides 5.7-kVRMS isolation.
Feature Summary
- Reinforced insulation for high-voltage isolation
- Dual-channel architecture with single input control
- High peak drive capability for fast switching
Applications
- Driving power MOSFETs in industrial inverters
- Gate driving for IGBT modules in motor drives
- Isolated interfaces in high-frequency power supplies
Procurement Notes
Verify the specific suffix (DW) confirms the 16-pin SOIC package and commercial/industrial temperature rating. Confirm the manufacturer is Texas Instruments. Check for RoHS compliance status and ensure the component matches the exact pinout requirements for your PCB layout. Validate that the single-input dual-output topology aligns with your system design constraints.
Selection Notes
Select this component when reinforced isolation and high peak current are required for dual-channel applications. The single-input feature simplifies control logic compared to independent dual inputs. Ensure the 5.7-kVRMS isolation rating meets safety standards for your application. Consider the 16-pin SOIC package size for board space constraints.
Part Context
This part belongs to Texas Instruments' UCC205xx series of isolated gate drivers. It is designed for robust performance in noisy environments where galvanic isolation is critical. The DW variant specifically denotes the standard plastic small-outline integrated circuit package.
Replacement Considerations
Check for direct cross-references from TI or authorized distributors. Verify if alternative parts offer compatible isolation ratings and peak currents. Ensure pin-to-pin compatibility if substituting in existing designs.
