TPS259231DRCR

Current Regulation/Management Overview

The TPS259231DRCR is a hot-swap voltage controller manufactured by Texas Instruments, designed for PCI power management applications. It operates within an input voltage range of 4.5 V to 5.5 V and supports a continuous current limit of up to 5 A. The device features a typical on-resistance of 28 mΩ and consumes a quiescent operating current of 470 µA. It is housed in a compact VSON-10 surface-mount package and functions reliably across an extended temperature range from -40 °C to +85 °C.

Current Regulation/Management Feature Summary

• Integrates high-side protection with adjustable current limiting capabilities
• Includes driver circuitry for external blocking FETs to prevent reverse current flow
• Provides comprehensive fault detection including overvoltage and thermal shutdown

Current Regulation/Management Applications

• PCI bus power distribution systems
• Hot-swap server backplane connections
• Industrial equipment input power stages

Current Regulation/Management Procurement Notes

Verify the specific suffix DRCR against the manufacturer datasheet to confirm the reel packaging configuration. Ensure the component matches the required 4.5 V to 5.5 V input specification for your target application. Cross-reference the VSON-10 footprint dimensions with your PCB design guidelines before finalizing procurement orders.

Current Regulation/Management Selection Notes

Select this model when a fixed 5 V input rail requires robust hot-swap protection without external gate drive complexity. The integrated blocking FET driver simplifies bill-of-materials compared to discrete solutions. Consider the 28 mΩ resistance for efficiency calculations in low-voltage, high-current scenarios where thermal dissipation is a primary constraint.

Current Regulation/Management Part Context

This component belongs to the TPS2592x family of integrated eFuses and hot-swap controllers. These devices consolidate power switch, control logic, and protection circuits into a single small form-factor package. The series targets applications requiring reliable power sequencing and fault isolation in dense electronic systems.

Current Regulation/Management Replacement Considerations

Consult official substitution guides for compatible parts within the same product family. Verify pin-to-pin compatibility and electrical parameter alignment before replacing the original component in existing designs.
