Overview
The UCC21551BDWKR is a dual-channel reinforced isolated gate driver from Texas Instruments, housed in a 14-pin SOIC package. It provides peak output currents of 4 A and 6 A with an insulation voltage of 5000 Vrms. The device operates within a junction temperature range of -40°C to +150°C and features a maximum propagation delay of 45 ns. Rise and fall times are specified at 8 ns each. Power dissipation reaches 950 mW, while the input supply voltage ranges up to 5.5 V. Output voltages span from 13 V to 25 V.
Feature Summary
- Supports universal configurations including dual low-side, dual high-side, or half-bridge driving applications.
- Provides reinforced electrical isolation with a 5000 Vrms insulation rating for safety-critical systems.
- Features programmable deadtime control to prevent shoot-through in bridge topologies.
Applications
- Industrial motor drives requiring robust galvanic isolation
- Solar micro-inverters and power conversion systems
- High-frequency switching power supplies
Procurement Notes
Verify the specific suffix 'BDWKR' against the manufacturer's current ordering guide to ensure correct packaging and tape-and-reel specifications. Confirm that the automotive qualification status matches project requirements, as this variant differs from the Q1-rated versions. Check for updated RoHS compliance documentation prior to final procurement approval.
Selection Notes
Select this component when a dual-channel driver with high-voltage reinforced isolation is required. It is suitable for applications needing independent control of two switches with programmable deadtime. Ensure the PCB layout supports the SOIC-14 footprint and thermal dissipation needs for 950 mW power handling.
Part Context
This part belongs to the UCC21551 family of capacitive coupled isolated gate drivers. It shares functional similarities with the UCC21550 but offers higher insulation voltage ratings. The BDWKR suffix indicates a specific reel quantity and tape configuration distinct from other variants like the DWKR or AQDWKRQ1.
Replacement Considerations
The UCC21550ADWKR is a related device but offers lower insulation voltage (1500 Vrms). Verify if the reduced isolation rating meets system safety standards before substitution. No direct pin-compatible substitutes with identical 5kVrms ratings are confirmed in public data.
