Overview
The UCC21541DWR is a reinforced isolation dual-channel gate driver from Texas Instruments, housed in a 16-SOIC package. It features up to 1.5 A source and 2.5 A sink peak output currents. The device provides 5700 Vrms channel-to-channel isolation with a 3.3 mm creepage distance. Key electrical parameters include a maximum propagation delay of 40 ns, rise time of 5 ns, and fall time of 6 ns. It operates within a temperature range of -40°C to +125°C and supports supply voltages from 9.2 V to 18 V.
Feature Summary
- Reinforced galvanic isolation with 5700 Vrms channel-to-channel rating
- Dual-channel architecture for driving power MOSFETs, IGBTs, and GaN devices
- High peak output current capability of 1.5 A source and 2.5 A sink
- Fast switching performance with low propagation delay and transition times
Applications
- Industrial motor drives
- Solar microinverters
- Switched-mode power supplies (SMPS)
- GaN-based power conversion systems
Procurement Notes
Verify the specific suffix 'DWR' corresponds to the 16-SOIC package and tape-and-reel packaging configuration. Confirm that the 5700 Vrms isolation rating meets the safety requirements of the target application. Ensure compatibility with the required logic input voltage levels and supply voltage range of 9.2 V to 18 V before procurement.
Selection Notes
Select this component when high-density dual-channel isolation is required for wide-bandgap or traditional power switches. The 3.3 mm creepage distance supports reinforced insulation standards. Compare against the UCC21542 variant if higher sink current (6 A) is needed. Ensure the SOIC-16 thermal dissipation characteristics fit the system's power budget.
Part Context
This part belongs to the UCC2154x family of isolated gate drivers designed for high-performance power conversion. The family shares similar isolation architectures but varies in output current capabilities. The UCC21541DWR specifically targets applications requiring moderate drive strength with robust isolation barriers.
Replacement Considerations
The UCC21542DWR offers higher sink current (6 A vs 2.5 A) with identical pinout and isolation ratings. Verify thermal management requirements if upgrading to higher current variants.
