UCC3912PWPG4

Overview

The UCC3912PWPG4 is a programmable hot swap power manager manufactured by Texas Instruments. It integrates control logic and power MOSFETs for single-channel protection in bus-powered applications. The device supports input voltages from 3V to 8V and delivers a maximum output current of 4A. It features an internal switch with synchronous rectification capabilities. The component operates within a junction temperature range of 0°C to 70°C. It is housed in a 24-HTSSOP package with a width of 4.40mm, designed for surface-mount installation.

Feature Summary

• Integrates programmable current limiting and fault timeout protection mechanisms
• Includes thermal shutdown and latch-off fault protection features
• Supports hot swap insertion without system reset or voltage droop

Applications

• Bus-powered peripheral cards
• CompactPCI backplane systems
• General-purpose hot swap power management

Procurement Notes

Verify the specific suffix 'PG4' against the manufacturer's official documentation to confirm RoHS compliance status and exact pinout configuration. Ensure the ordering information matches the required package variant and environmental specifications before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring integrated current limiting and thermal protection in compact form factors. Consider the 24-pin HTSSOP package constraints and the 4A current capability when designing power stages. Verify compatibility with the target bus voltage range of 3V to 8V during the initial design phase.

Part Context

This part belongs to the UCC3912 family of programmable hot swap controllers.
