UCC23513BDWYR

Overview

The UCC23513BDWYR is a single-channel opto-compatible isolated gate driver from Texas Instruments, housed in a SOIC-6 package. It provides high-voltage isolation with a reinforced insulation rating of 5700 Vrms. The device features a peak output current capability of 4 A source and 5 A sink, supporting fast switching speeds with typical rise and fall times of 28 ns and 25 ns, respectively. Maximum propagation delay is specified at 105 ns. It operates within an extended temperature range from -40°C to +125°C and requires a supply voltage between 15 V and 30 V.

Feature Summary

• Opto-compatible architecture enables direct replacement for legacy optocoupler-based designs without circuit modification.
• Provides robust galvanic isolation suitable for high-noise industrial environments and safety-critical applications.
• Integrated bootstrap diode simplifies high-side driver implementation in half-bridge configurations.

Applications

• Industrial motor drives and inverters
• Solar micro-inverters and string inverters
• Uninterruptible power supplies (UPS)
• High-frequency switched-mode power supplies

Procurement Notes

Verify the specific suffix 'DWYR' confirms the reel packaging format required for automated surface-mount assembly processes. Confirm that the component meets RoHS directives and humidity sensitivity level requirements for your manufacturing floor conditions. Ensure the ordering part number matches the exact tape-and-reel quantity specifications defined by the manufacturer for your production line equipment compatibility.

Selection Notes

Select this component when replacing existing discrete optocouplers and gate drivers to reduce board space and improve switching performance. The opto-compatible pinout allows for straightforward design upgrades without altering the printed circuit board layout. Consider the 5.7 kVrms isolation rating to ensure adequate creepage and clearance distances are maintained for the target application's safety standards and operating voltage levels.

Part Context

This device belongs to the UCC2351x family of isolated gate drivers designed to bridge the gap between traditional optocouplers and advanced digital isolators. It combines the ease of integration found in optocouplers with the speed and reliability of solid-state isolation technology. The family targets applications requiring high channel count and precise timing synchronization in power conversion systems.

Replacement Considerations

Direct pin-to-pin replacements include the UCC23511 and UCC23512 variants within the same series, which offer similar isolation ratings but may differ in specific drive strength or feature sets. Verify that any substitute maintains the same SOIC-6 footprint and electrical characteristics to ensure mechanical and functional compatibility.
