Overview
The UCC21541DW is a reinforced isolation dual-channel gate driver from Texas Instruments, housed in a 16-pin SOIC package. It provides peak source and sink currents of 1.5 A and 2.5 A, respectively. The device features a 5700 Vrms reinforced isolation voltage and operates with an 8 V UVLO threshold. Electrical characteristics include a maximum propagation delay of 40 ns, with rise and fall times of 16 ns and 12 ns. It supports a supply voltage range of 6.5 V to 25 V and functions within temperatures from -40 °C to 150 °C.
Feature Summary
- Provides reinforced isolation for high-voltage safety compliance
- Features dual independent channels for H-bridge or half-bridge configurations
- Includes a dedicated disable pin for system control
Applications
- Industrial motor drives
- Inverter systems
- Switched-mode power supplies
Procurement Notes
Verify the specific suffix 'DW' confirms the 16-pin SOIC package and standard operating temperature range. Confirm that the component meets the required reinforced isolation standards for your application's safety regulations. Ensure the ordering information matches the exact current ratings of 1.5 A/2.5 A specified for this variant.
Selection Notes
Select this component when reinforced isolation is mandatory rather than functional isolation. Compare against the UCC21542 series if higher peak currents of 4 A/6 A are required. Consider the UCC21540Q variant if automotive qualification under AEC-Q100 is necessary for the design.
Part Context
This part belongs to the UCC2154x family of isolated gate drivers designed for driving power MOSFETs, IGBTs, and GaN devices. The family shares a common architecture but varies in output current capabilities and packaging options to suit different power density requirements.
Replacement Considerations
The UCC21542DW offers higher drive strength at 4 A/6 A. The UCC21540QDWKRQ1 provides automotive-grade reliability. Verify pinout compatibility before substituting.
