UCC5614PWPTR

Overview

The UCC5614PWPTR is a high-speed, low-side MOSFET gate driver manufactured by Unitrode. It features a push-pull output stage capable of delivering high peak currents to rapidly switch external N-channel power MOSFETs. The device operates with a supply voltage range typically spanning from 4.5V to 20V, ensuring compatibility with various logic families and power stages. It incorporates built-in protection mechanisms such as under-voltage lockout (UVLO) to prevent improper operation during power-up and power-down sequences. The component is designed for use in motor drives, solar inverters, and DC-DC converters where efficient switching performance is critical.

Feature Summary

• High-speed switching capability for reduced conduction losses
• Integrated under-voltage lockout for reliable operation
• Push-pull output architecture for strong drive strength

Applications

• Motor control systems
• Solar micro-inverters
• Isolated DC-DC converter topologies

Procurement Notes

Verify the specific suffix 'PWPTR' indicates the SSOP-8 plastic package and tape-and-reel packaging format. Confirm that the manufacturer designation aligns with the original Unitrode specifications or current Texas Instruments lineage, as corporate acquisitions may affect documentation sources. Ensure the operating temperature range matches the commercial grade requirements of the target application environment before finalizing procurement orders.

Selection Notes

Select this component when driving low-side N-channel MOSFETs in applications requiring fast transition times and moderate current drive capabilities. Consider the thermal dissipation characteristics of the SSOP-8 package if high duty cycles are expected. Evaluate the input logic voltage levels to ensure compatibility with the controlling microcontroller or PWM generator without requiring additional level-shifting circuitry.

Part Context

Unitrode was a prominent designer of analog and mixed-signal integrated circuits, particularly known for power management solutions. The company was acquired by Texas Instruments, which continues to support and manufacture many of its legacy product lines. The UCC5614 belongs to the family of gate drivers developed to address the growing demand for efficient power conversion in industrial and consumer electronics markets.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as the UCC5613 or UCC5615, depending on required drive current and isolation specifications. Verify that any substitute maintains the same package outline dimensions and electrical characteristics to ensure seamless integration into existing PCB layouts.
