Product details
Overview
TPS259823ONRGER from Texas Instruments is a smart eFuse IC providing integrated hot-swap protection for 2.7V–24V power rails, featuring 2.7mΩ typical RON, ±1.5% accurate current monitoring (IOUT > 3A), 7.6V fixed overvoltage lockout, and circuit breaker response mode. It delivers robust short-circuit protection with <400ns fast-trip response and supports remote fault recovery via configurable auto-retry.
For engineers reviewing the TPS259823ONRGER datasheet, TPS259823ONRGER pinout, TPS259823ONRGER application, or TPS259823ONRGER equivalent, this device is selected for high-reliability server standby rail protection, PCIe riser power management, and industrial PC hot-plug subsystems where precise current limiting, transient immunity, and UL 2367/IEC 62368 compliance are required.
Technical Context
The TPS259823ONRGER implements a precision analog current-sense amplifier feeding a comparator-based fault detection engine, with independent timers for overcurrent blanking (ITIMER), retry delay (RETRY_DLY), and retry count (NRETRY). Its circuit breaker mode latches off on sustained overcurrent, distinguishing faults from transients using programmable blanking intervals.
It integrates dual-threshold overvoltage protection (7.6V rising/falling thresholds), adjustable undervoltage lockout via EN/UVLO resistor divider, and dV/dt-controlled output slew rate. Thermal shutdown at 150°C with 10°C hysteresis ensures safe operation under overload conditions across –15°C to 125°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 24V - supports low-voltage embedded rails and 12V/24V industrial systems without external regulation |
| RON (typ) | 2.7mΩ - enables ≤33mV I×R drop at 12A, minimizing power loss and thermal rise |
| Current Limit Range | 2A to 15A - set by single RILIM resistor (100Ω–1650Ω), ±8% accuracy above 5A |
| Overvoltage Threshold | 7.6V (rising), 7.4V (falling) - fixed OVLO option prevents damage from supply surges in mid-range voltage systems |
| Current Monitor Accuracy | ±1.5% (typ, 25°C, IOUT > 3A) - enables high-fidelity load telemetry for system health monitoring |
| Fast-Trip Response | <400ns - detects hard shorts before MOSFET energy dissipation causes failure |
| Operating Junction Temp | –15°C to 125°C - qualified for industrial and datacenter environments with forced-air or PCB conduction cooling |
Pinout & Package
TPS259823ONRGER is housed in a thermally enhanced 4mm × 4mm QFN-24 package (RGE) with dual exposed thermal pads (Pad 1 connected to IN, Pad 2 to GND) for optimal power dissipation and current distribution.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pins 1,2,3,16; Pad 1) | Power Input | High-current input node; exposed pad must be soldered to input plane for thermal and current handling |
| OUT (Pins 17–24) | Power Output | Eight paralleled output terminals reduce trace resistance and improve current sharing |
| GND (Pins 4,5,14; Pad 2) | Ground Reference | Low-impedance return path; Pad 2 ties to system ground for thermal relief and noise control |
| EN/UVLO (Pin 6) | Enable / UVLO Input | Active-high enable with resistor-divider programmable undervoltage threshold (1.2V nominal) |
| ILIM (Pin 8) | Current Limit Set | Connects to GND via resistor to define both current limit and fast-trip thresholds |
| IMON (Pin 9) | Current Monitor Output | Sources 246µA/A proportional current; convert to voltage with external resistor for ADC sensing |
| RETRY_DLY (Pin 10) | Auto-Retry Delay | Capacitor-to-GND sets time between fault shutdown and next restart attempt; open = latch-off |
| NRETRY (Pin 11) | Retry Count Control | Capacitor-to-GND sets finite retry count; short to GND = infinite retries |
| LDSTRT (Pin 12) | Load Detect Handshake | Capacitor-to-GND defines handshake window after PG assertion; connect to GND to disable |
| PG (Pin 13) | Power Good Output | Open-drain signal asserted when FET is fully enhanced and VOUT ≥ VIN − 0.326V |
| dVdt (Pin 15) | Slew Rate Control | Capacitor-to-GND adjusts output turn-on dV/dt; floating = fastest ramp (7.4 V/ms at 24V) |
| ITIMER (Pin 7) | Overcurrent Blanking Timer | Capacitor-to-GND sets blanking interval to ignore benign inrush/load transients |
Key Features
| Feature | Design Value |
|---|---|
| UL 2367 Recognition (E339631) | Validated for end-equipment safety compliance in commercial/industrial systems requiring third-party certification |

| Adjustable Fault Response Mode | Configurable latch-off or auto-retry behavior with user-defined retry count and inter-retry delay |
| Robust Short-Circuit Immunity | Tested for 1 million power-into-short cycles with no degradation; immune to line transients |
| Accurate Load Current Monitoring | ±1.5% typical gain error enables real-time load diagnostics and predictive maintenance |
| Programmable Output Slew Rate | Controls inrush current via dV/dt capacitor; prevents supply sag and contact arcing during hot-insertion |

Equivalent & Alternatives
The following parts are listed as comparable options for similar eFuse applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS259823LNRGE | Same package and pinout; active current limiter instead of circuit breaker response mode | Preferred for constant-current loads (e.g., LED drivers) where sustained overcurrent must be maintained rather than interrupted | Select when continuous current delivery during overload is required; not drop-in for latch-off use cases |
| TPS259421ARVCR | Lower voltage range (2.7V–18V), 3.5mΩ RON, fixed 15A current limit, no adjustable OVLO | Targeted at cost-sensitive consumer electronics with simpler protection needs and no requirement for multi-threshold OVLO | Choose for simplified design with fixed parameters; lacks programmable retry, dV/dt, and 7.6V OVLO specificity |
Compared with TPS259823ONRGER, TPS259823LNRGE offers identical protection thresholds but sustains current during overloads, while TPS259421ARVCR trades configurability for lower cost and reduced feature set-making the TPS259823ONRGER optimal for systems needing programmable fault recovery and precise 7.6V overvoltage clamping.

FAQ
What is the overvoltage lockout threshold for TPS259823ONRGER?
The TPS259823ONRGER features a fixed overvoltage lockout threshold of 7.6V (rising) and 7.4V (falling), verified per TI SLVSEI3D datasheet Section 6.5. This variant is optimized for 5V–12V intermediate bus rails where transient overvoltage exceeds standard LDO tolerance but remains below 8V. The threshold is internally trimmed and does not require external components.
How does TPS259823ONRGER differ from TPS259822ONRGER?
The TPS259823ONRGER and TPS259822ONRGER share identical circuit breaker functionality and pinout but differ in overvoltage lockout thresholds: TPS259823ONRGER uses 7.6V, while TPS259822ONRGER uses 3.7V. Both support 2A–15A current limiting via RILIM, but the OVLO selection determines suitability for specific input rail voltages-TPS259823ONRGER is intended for 5V/12V systems, not 3.3V domains.
Can TPS259823ONRGER be used in automotive applications?
The TPS259823ONRGER is not AEC-Q100 qualified and operates over –15°C to 125°C junction temperature, which falls short of automotive Grade 2 (–40°C to 105°C ambient) requirements. Its UL 2367 and IEC 62368 certifications target industrial and datacenter equipment-not automotive ECUs or infotainment systems. For automotive use, TI recommends the TPS25947 or TPS2595xx families.
What is the minimum RILIM value supported by TPS259823ONRGER?
The TPS259823ONRGER supports RILIM down to 100Ω, enabling a maximum current limit of 14.71A (typical) at 25°C, as specified in Section 6.5 of the SLVSEI3D datasheet. At this setting, the device maintains ±8% accuracy for ILIM > 5A and retains full functionality including fast-trip detection and current monitoring. Values below 100Ω are not characterized and may compromise accuracy or reliability.
Does TPS259823ONRGER provide reverse current blocking?
No, the TPS259823ONRGER does not include internal reverse current blocking. It is a single-channel, N-channel MOSFET-based eFuse with unidirectional current flow (IN to OUT only). If reverse current protection is required-for example, to prevent backfeed from downstream capacitors-the system must implement an external Schottky diode or ideal diode controller in series with the TPS259823ONRGER output.
