Product Overview
The TPS2595 is a Texas Instruments 4-A eFuse hot-swap protection IC for Power_Management designs that require controlled input-to-output power-path protection. It operates from 2.7 V to 18 V on TPS2595x0/1/3 variants or 3.0 V to 18 V on TPS2595x5 variants, with OUT recommended from 0 V to VIN + 0.3 V.
The device integrates a low-resistance pass path, specified at 34 mΩ typical and 37 mΩ maximum at VIN = 4 V to 18 V and TJ = 25°C. Current limiting is set with the ILM pin over a recommended 487 Ω to 5000 Ω range, and current monitor gain is specified on the ILM pin at both 4 A and 1 A load conditions.
Protection and control functions include IN undervoltage protection, overvoltage clamp thresholds for TPS25952x, TPS25953x, and TPS25954x variants, output clamp response down to 5 us at 4 A, and short-circuit response of 5 us. The DSG WSON 8-pin package has 65.6°C/W junction-to-ambient thermal resistance and 9.8°C/W junction-to-case bottom thermal resistance.

Procurement Notes
When requesting a quote for TPS2595, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For power IC and power device sourcing, voltage rating, current rating, power dissipation, package thermal performance, protection features, qualification grade and application conditions should be reviewed before approval.
FAQ
What input voltage range does the TPS2595 support?
The TPS2595 family has two recommended input ranges. TPS2595x0, TPS2595x1, and TPS2595x3 variants operate from 2.7 V to 18 V, while TPS2595x5 variants operate from 3.0 V to 18 V.
What continuous output current is specified for TPS2595?
The device is specified for 4 A continuous output current from IN to OUT over TJ = -40°C to 125°C. It also has a 5 A continuous output current condition over TJ = -40°C to 105°C, guaranteed by design.
How is the TPS2595 current limit configured?
Current limiting is configured through the ILM pin. The recommended ILM resistance range for active current limiting is 487 Ω to 5000 Ω, with extracted current-limit examples from 0.49 A typical to 4.17 A typical.
What package is used for the TPS2595?
TPS2595 is listed in a DSG WSON 8-pin package with a 2.00 mm x 2.00 mm body. The extracted thermal data for this package includes 65.6°C/W junction-to-ambient and 9.8°C/W junction-to-case bottom resistance.
What protection response times are specified for TPS2595?
The extracted facts specify a 5 us short-circuit response time from IOUT greater than ISC to IOUT less than or equal to ILIMIT. Current-limit response time is 250 us when IOUT exceeds ILIMIT by more than 20%.
