UCC23514MDWV

Overview

The UCC23514MDWV is a single-channel optically isolated gate driver manufactured by Texas Instruments. It operates within a supply voltage range of 15 V to 30 V and delivers a peak output current of 5 A. The device provides 5 kVrms reinforced isolation and supports high-side and low-side configurations. Key timing parameters include a maximum propagation delay of 105 ns, with rise and fall times of 28 ns and 25 ns respectively. It functions reliably across an operating temperature range from -40°C to +125°C and is housed in an SOIC-8 package.

Feature Summary

• Provides 5 kVrms reinforced optical isolation for safe signal transmission between control and power stages.
• Delivers robust 5 A sink and 4 A source drive capability for efficient switching of power devices.
• Features fast switching performance with low propagation delay and minimal rise/fall times.
• Compatible with standard CMOS logic inputs for straightforward interface integration.

Applications

• Industrial motor drives
• Inverter circuits
• Switched-mode power supplies

Procurement Notes

Verify the specific suffix 'MDWV' against the manufacturer's latest datasheet to confirm pinout and electrical specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Check for any Product Change Notifications (PCN) or End-of-Life (EOL) notices that may affect long-term availability or manufacturing changes. Confirm humidity sensitivity level (MSL) handling procedures during storage and reflow soldering.

Selection Notes

Select this component when high-voltage isolation is required between low-power control logic and high-power switches. The single-channel design suits applications needing independent control of one switch. Consider the 5 A drive strength for medium-power MOSFETs or IGBTs. Evaluate the SOIC-8 package size against PCB space constraints. Verify that the input logic levels match the driving microcontroller or DSP outputs.

Part Context

This part belongs to the UCC23514 series of optically isolated gate drivers. It shares core specifications with variants like UCC23514VDWVR but differs in packaging and potentially qualification status. The series is designed for applications requiring galvanic isolation in power electronics. Other members may offer dual-channel options or different thermal ratings.

Replacement Considerations

Direct substitutes include UCC23514VDWVR and UCC23514SDWVR, though pinouts and channel counts may vary. Verify compatibility before swapping. Generic replacements require matching isolation voltage, drive current, and package type.
