UCC21540DWK

Overview

The UCC21540DWK is a dual-channel reinforced isolated gate driver from Texas Instruments, housed in a 14-pin SOIC package. It features a 4-A source and 6-A sink output capability with a maximum propagation delay of 40 ns. The device supports a supply voltage range of 8.0 V to 25 V for the high-side channel and 6.5 V to 25 V for the low-side channel. It operates within a temperature range of -40°C to +150°C and provides 5700 Vrms isolation voltage.

Feature Summary

Reinforced isolation with 3.3 mm channel-to-channel spacing
Dual-channel architecture with independent control inputs
Programmable dead-time insertion for bridge applications
Integrated disable function for safe shutdown

Applications

Automotive traction inverters
On-board chargers (OBC)
DC-DC converters
Industrial motor drives

Procurement Notes

Verify the specific suffix 'DWK' indicates the tape-and-reel packaging variant. Confirm automotive qualification status if required for AEC-Q100 compliance. Ensure the 14-pin SOIC footprint matches the PCB layout. Check for updated datasheet revisions to confirm pinout consistency.

Selection Notes

Select this component for applications requiring high current drive with robust galvanic isolation. The 4A/6A peak current suits medium-power MOSFETs and IGBTs. Consider the 14-pin package constraint versus the 16-pin DW variant when designing enclosure space. Verify input logic compatibility with the controller MCU.

Part Context

Part of the UCC2154x family of reinforced isolated gate drivers. Designed for high-reliability power conversion systems. Shares architectural similarities with UCC21520 but offers distinct packaging and specific isolation ratings. Targets electric vehicle and industrial power electronics markets.
