M-option means an internal Miller clamp
UCC23514MDWVR is the UCC23514M version of TI’s single-channel opto-compatible isolated gate driver. The M designation selects the integrated Miller-clamp function that helps limit false gate turn-on caused by Miller current. The family also has V, S and E versions with different output/UVLO arrangements; their suffix behavior should not be copied into the M-orderable’s pin description.
Peak gate drive is not load output current
Its 4.5 A source and 5.3 A sink capabilities refer to peak gate-charging and discharging currents, not current supplied continuously to a motor or power load. The secondary driver supply is specified from 12 to 33 V. The headline 105 ns maximum propagation-delay figure must be interpreted under the test conditions of the data sheet, with gate-charge and wiring choices affecting the practical switching waveform.
Isolation, creepage, and certification wording
The DWV package is an eight-terminal SOIC-style implementation with a stated 8.5 mm creepage distance. TI describes a 5.0 kVrms isolation rating, but it is not a normal continuous voltage to be placed across the barrier. An older data sheet uses the word ‘Planned’ for some safety-related certifications; procurement should reconfirm current certificates rather than importing that list as an unconditional compliance claim.
Verified selection specifications
| Selection parameter | TI-sourced value | Required interpretation |
|---|---|---|
| Peak source sink | 4.5A source / 5.3A sink peak | Transient output gate charging/discharging, not load current |
| Isolation | 5.0kVrms | Specified insulation withstand per test, not continual common-mode voltage |
| Driver supply | 12–33 V | Secondary driver supply not logic input voltage |
| Prop delay max | 105 ns max | Test conditions apply |
| Miller variant | Integrated Miller clamp | Exact M variant; not V/S/E output alternatives |
| Package | DWV SOIC 8, 8.5mm creepage | LCSC SOIC-8-300mil catalog label |
| Temperature | −40 to +150°C junction | Junction operating range, not ambient |
| Certification | Planned historical certification note | Do not claim certifications completed without checking current public database |
For another opto-compatible isolated gate-driver family, compare UCC23513DWYR. TI lists 5.7 kVRMS isolation for the UCC23513 family versus 5.0 kVRMS withstand for UCC23514; this exact UCC23514M includes an internal Miller clamp. Differences in pin assignment, clamp output, UVLO and test-rated insulation must be confirmed before any circuit substitution.
Exact-part sourcing
Quote UCC23514MDWVR as the complete orderable number. The catalog package label is SOIC-8-300mil; use the corresponding TI mechanical drawing and verify the electrical and mounting constraints before approving any different MPN. Stock confirmation, quoted pricing, quantity and delivery terms must be checked through RFQ rather than assumed from this product page.
