Texas Instruments TPS259260DRCR

Overview

TPS259260DRCR from Texas Instruments is a 12-V eFuse protection switch with integrated 30-mΩ pass MOSFET, fixed 15-V over-voltage clamp, adjustable 2–5-A current limit (±15% accuracy), programmable dV/dT ramp control, and latched thermal shutdown. It protects downstream loads in 12-V auxiliary power rails against overcurrent, short circuit, overvoltage, and inrush surges.

For engineers reviewing the TPS259260DRCR datasheet, TPS259260DRCR pinout, TPS259260DRCR application, or TPS259260DRCR equivalent, key selection criteria include OVP clamp voltage (15 V), latch-mode fault response, ILIM resistor programming range (10–162 kΩ), VSON-10 package thermal performance (R_θJA = 45.9°C/W), and EN/UVLO dual-function pin behavior under noisy supply conditions.

Technical Context

The TPS259260DRCR implements a high-side hot-swap controller with fast-trip comparator (IFASTRIP = 1.6 × IOL) for sub-μs short-circuit response, internal charge-pump gate drive for low R_DS(on), and UVLO monitoring (4.3 V rising threshold) before enabling the pass FET. Its dV/dT pin uses a 220-nA constant-current source and 70-pF internal capacitance to generate programmable output slew rates via external capacitor.

Thermal shutdown triggers at 150°C (10°C hysteresis) and latches until EN/UVLO is toggled; no auto-retry occurs. Overvoltage clamping activates when VIN exceeds 16.5 V, limiting VOUT to 13.8–16.5 V (typ. 15 V) without external components. Current limit is set by ILIM-to-GND resistor with ±15% accuracy across –40°C to +125°C.

FAQ

What is the over-voltage clamp voltage of the TPS259260DRCR?

The TPS259260DRCR features a fixed 15-V over-voltage clamp (VOVC), specified from 13.8 V to 16.5 V across temperature and load. This clamp activates automatically when VIN exceeds 16.5 V, limiting VOUT to protect downstream 12-V components without requiring external components. The TPS259260DRCR is designed for 12-V systems where this clamp aligns with common IC absolute maximum ratings.

How is current limit set on the TPS259260DRCR?

Current limit on the TPS259260DRCR is set by connecting a resistor (RILIM) between the ILIM pin and GND. With RILIM = 100 kΩ, the overload current limit is 3.75 A (±15%); values from 10 kΩ to 162 kΩ yield 2–5 A. The TPS259260DRCR also includes single-point-failure safeguards: open RILIM yields 0.73 A, shorted RILIM yields 0.84 A.

Does the TPS259260DRCR support programmable output voltage ramp rate?

Yes-the TPS259260DRCR supports programmable dV/dT via an external capacitor connected from the dV/dT pin to GND. A 1-nF capacitor yields ~12 ms ramp time for 12-V output; no capacitor gives 0.7–1.3 ms. The internal 220-nA current source and 70-pF capacitance define the timing equation. This feature is integral to the TPS259260DRCR's inrush control capability.

What happens during thermal shutdown on the TPS259260DRCR?

When junction temperature exceeds 150°C, the TPS259260DRCR enters latched thermal shutdown: the internal MOSFET turns off and remains off until EN/UVLO is toggled (pulled low then high) or power is cycled. Unlike auto-retry variants, the TPS259260DRCR does not self-recover-ensuring persistent fault isolation critical for safety-critical 12-V rails.

Is the TPS259260DRCR UL-recognized?

Yes-the TPS259260DRCR is UL 2367 recognized (File No. E339631), confirming compliance with end-equipment safety standards for overcurrent and overtemperature protection. This recognition applies specifically to the TPS259260DRCR device and supports faster system-level safety certification in industrial and computing applications.
