Overview
The UCC21550ADWR is a dual-channel reinforced isolated gate driver from Texas Instruments, housed in a 16-pin SOIC package. It features programmable deadtime and a disable function for precise control. The device supports peak output currents of 4A and 6A with a propagation delay of up to 45ns. It operates within a wide temperature range of -40°C to +150°C and provides 5000Vrms isolation voltage.
Feature Summary
- Dual-channel design with independent input and output channels
- Programmable deadtime generation for optimized switching performance
- Integrated disable function for enhanced system safety
- Reinforced insulation rating for high-voltage isolation requirements
Applications
- Industrial motor drives
- Solar microinverters
- High-frequency power supplies
Procurement Notes
Verify the specific suffix 'ADWR' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance standards required by your region. Cross-reference the ordering part number with official distributor catalogs to avoid counterfeit components. Confirm that the thermal dissipation capabilities align with your PCB layout constraints.
Selection Notes
Select this component when dual-channel isolation with programmable deadtime is required. It is suitable for applications demanding high reliability and wide operating temperatures. Compare its 4A/6A drive strength against other models if higher current capability is needed. Consider the SOIC-16 footprint compatibility during PCB design phase.
Part Context
This part belongs to the UCC21550 family of isolated gate drivers. It shares functional similarities with the UCC21540 but offers different insulation ratings and package options. The ADWR variant specifically denotes the SOIC-16 surface-mount package configuration.
Replacement Considerations
The UCC21550ADWR may be replaced by the UCC21550ADWKR, which shares similar electrical characteristics but differs in packaging format. Verify pinout compatibility before substitution.
