Overview
The UCC5870QDWJRQ1 is a current-isolated gate driver designed for automotive applications, featuring a single-channel configuration. It provides 3.75 kVrms isolation and delivers a peak output current of 30 A. The device operates within an extended temperature range from -40°C to +125°C. Key electrical parameters include a maximum propagation delay of 150 ns, with rise and fall times both specified at 150 ns. It is housed in an SSOP-36 package and supports surface-mount installation.
Feature Summary
- Provides galvanic isolation via a capacitive coupling architecture suitable for high dv/dt environments
- Delivers high peak drive current capability for fast switching of power devices
- Complies with automotive functional safety standards for reliability in vehicle systems
Applications
- Automotive traction inverters
- On-board chargers (OBC)
- DC-DC converters in electric vehicles
Procurement Notes
Verify the specific suffix 'RQ1' confirms automotive qualification and reel packaging. Ensure the SSOP-36 footprint matches your PCB layout constraints. Confirm RoHS compliance status through official Texas Instruments documentation before finalizing procurement specifications.
Selection Notes
Select this component when high peak current drive is required alongside robust isolation. The 30 A output suits wide-bandgap semiconductors like SiC MOSFETs. Consider the 150 ns propagation delay for timing-sensitive control loops. Verify thermal management requirements for the SSOP-36 package under continuous load conditions.
Part Context
This part belongs to the UCC5870-Q1 family of isolated gate drivers. It is distinct from lower-current variants like the UCC21710. The Q1 designation indicates automotive grade qualification. The DWJR package code specifies the SSOP-36 body and tape-and-reel delivery method.
Replacement Considerations
Direct substitutes may include other UCC5870-Q1 variants with different package options or suffixes. Verify pin compatibility and isolation voltage ratings before substitution. Consult Texas Instruments for cross-reference data.
