TPS25972LRPWR

Overview

The TPS25972LRPWR is a single-channel hot-swap voltage controller and eFuse manufactured by Texas Instruments. It operates within an input voltage range of 2.7 V to 23 V and supports a continuous load current up to 5.5 A. The device features a typical on-resistance of 28 mΩ, contributing to low conduction losses. It incorporates integrated power monitoring capabilities for accurate current sensing and protection. The component is housed in a VQFN-10 package with dimensions of 2 mm by 2 mm, designed for surface-mount applications.

Feature Summary

Integrates precise current monitoring for accurate power management
Provides transient overcurrent blanking to prevent false triggering
Features controlled slew rate to minimize inrush current during startup

Applications

Smart electricity meters requiring robust power protection
USB-Type C systems utilizing fast role swap linear oring
Industrial equipment needing reliable hot-swap insertion support

Procurement Notes

Verify the specific suffix 'LRPWR' against the official Texas Instruments datasheet to confirm the exact tape-and-reel packaging quantity and moisture sensitivity level. Ensure that the ordering configuration matches the required thermal pad exposure and pinout specifications for the VQFN-10 package. Cross-reference the RoHS compliance status and lead time requirements directly with authorized distributors prior to finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require high-voltage tolerance up to 23 V combined with precise current limiting. It is suitable for applications demanding accurate power monitoring without external sense resistors. Consider the 28 mΩ on-resistance for efficiency calculations and ensure the PCB layout accommodates the exposed thermal pad for adequate heat dissipation under maximum load conditions.

Part Context

This part belongs to the TPS25947 series of hot-swap controllers from Texas Instruments. While sharing similar architectural features with other members of the family, it is distinguished by its specific current rating and resistance characteristics. The series is designed to provide comprehensive protection for downstream loads in various power distribution networks.
