TPS259530DSGR

Current Regulation/Management Overview

The TPS259530DSGR is a hot-swap voltage controller from Texas Instruments, functioning as an electronic fuse. It supports input voltages from 2.7 V to 18 V and manages output currents ranging from 0.5 A to 4 A. The device is housed in an 8-pin WSON package with dimensions of 2 mm x 2 mm. It operates within a junction temperature range of -40°C to +125°C. Key electrical parameters include a current limit accuracy of ±7.5% and integrated power fail detection capabilities.

Current Regulation/Management Feature Summary

• Integrates high-side N-channel MOSFET for efficient power path control
• Provides programmable current limiting to protect against overcurrent conditions
• Includes adjustable rise time to manage inrush current during startup
• Features integrated fast discharge to rapidly remove charge from output capacitors

Current Regulation/Management Applications

• Hot-swap applications requiring controlled power insertion
• System protection for downstream circuitry against short circuits
• Power distribution units managing multiple load rails
• Industrial equipment requiring robust fault handling

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DSGR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the thermal performance requirements align with the 8-WSON package specifications under expected operating loads. Ensure compatibility with the target input voltage range of 2.7 V to 18 V before finalizing procurement orders.

Current Regulation/Management Selection Notes

Select this component when designing systems that require precise current limiting and hot-swap functionality within a compact footprint. It is suitable for applications needing wide input voltage coverage and industrial-grade temperature stability. Consider the trade-off between the fixed current limit options available within the TPS2595xx family to match the specific load requirements.

Current Regulation/Management Part Context

This part belongs to the TPS2595xx series of eFuses and hot-swap controllers. It shares the same 8-WSON package and core architecture with variants like TPS259533DSGR and TPS259541DSGR. The primary differentiation lies in the internal current limit settings, allowing designers to choose specific ratings without changing the physical layout or control logic.

Current Regulation/Management Replacement Considerations

Direct substitutes within the same family include TPS259533DSGR and TPS259541DSGR, which share identical pinouts and packages but offer different current limit thresholds. Verify that the alternative part's current rating meets the system's maximum load requirements.
