UCD7100APWP

Overview

The UCD7100APWP is a digital control compatible single low-side MOSFET driver manufactured by Texas Instruments. It provides ±4-A peak drive current to support fast switching transitions in power conversion applications. The device integrates an on-chip current sense amplifier with programmable gain and delay, enabling precise cycle-by-cycle current monitoring without external components. Designed for high-frequency operation, it features a wide supply voltage range and robust EMI performance through spread-spectrum frequency modulation.

Feature Summary

• Integrated current sense amplifier with programmable gain and delay for accurate cycle-by-cycle protection
• Digital control compatibility supporting I2C configuration for flexible system integration
• Spread-spectrum frequency modulation capability to reduce electromagnetic interference emissions

Applications

• Point-of-load DC-DC converters
• Server and workstation power supplies
• Telecommunications power systems

Procurement Notes

Verify the specific suffix 'PWP' corresponds to the TSSOP-16 package variant when sourcing. Confirm RoHS compliance status via the manufacturer's official documentation. Ensure the component meets automotive or industrial qualification requirements if applicable to the target design environment.

Selection Notes

Select this driver for designs requiring integrated current sensing to minimize bill of materials. Evaluate the need for digital control interfaces versus analog inputs based on system architecture. Consider the thermal performance of the TSSOP-16 package relative to the expected continuous operating current and ambient conditions.

Part Context

This component belongs to the UCD7100 family of gate drivers designed for synchronous buck converter applications. It replaces discrete driver and sense amplifier solutions by integrating both functions into a single compact package. The family targets high-efficiency power stages in computing and communication infrastructure.

Replacement Considerations

Check UCD7100A variants for pin-compatible alternatives. Verify functional equivalence regarding current sense accuracy and digital interface protocols before substitution.
