Product details
Overview
TPS26625DRCT from Texas Instruments is a 60-V, 800-mA industrial eFuse with integrated input and output reverse polarity protection, 478-mΩ total RON, ±5% current limit accuracy at 880 mA, and auto-retry fault response-designed for PLC I/O modules and AC/servo drives requiring robust surge immunity per IEC 61000-4-5.
For engineers reviewing the TPS26625DRCT datasheet, TPS26625DRCT pinout, TPS26625DRCT application, or TPS26625DRCT equivalent, key selection criteria include its dual reverse polarity protection (input and output), adjustable 25–880-mA current limit, 0.3-µs reverse current blocking, 340-µA operating quiescent current, and 3 mm × 3 mm VSON-10 package with PowerPAD™ thermal enhancement.
Technical Context
The TPS26625DRCT implements back-to-back N-channel MOSFETs to enable bidirectional reverse polarity blocking-supporting both input-side (–60 V) and output-side (–(60 – VIN)) protection. Its internal control loop integrates programmable UVLO, OVP cutoff, dV/dt slew rate control via external capacitor, and fast-trip short-circuit detection with 220 ns typical response.
Unlike latch-off variants (e.g., TPS26624), the TPS26625DRCT uses auto-retry behavior for overcurrent and overtemperature faults, enabling autonomous recovery without external reset. It operates across –40°C to +125°C and meets UL 2367 (File No. 169910) and IEC 62368-1 safety certifications.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Input Voltage Range | 4.5 V to 60 V - supports common industrial DC bus voltages including 24 V and 48 V systems |
| Current Limit Range | 25 mA to 880 mA (±5% accuracy at 880 mA) - enables precise load protection without overdesigning upstream power stages |
| Total RON | 478 mΩ max at 25°C - limits conduction loss to ≤450 mW at 800 mA, reducing thermal stress |
| Reverse Blocking Speed | 0.3 µs response - prevents damaging reverse current flow during hot-swap or brownout events |
| Quiescent Current | 340 µA in operation / 12 µA in shutdown - minimizes standby power in always-on industrial nodes |
| Package | VSON-10 (3 mm × 3 mm) with exposed PowerPAD™ - delivers 3.4°C/W bottom-side thermal resistance for high-power reliability |

Pinout & Package
VSON-10 (DRCT) package with 3.00 mm × 3.00 mm body size and thermally enhanced PowerPAD™ connected to RTN for optimal heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Power input | High-voltage supply rail connection (4.5–60 V); withstands –60 V reverse input |
| 2 UVLO | Undervoltage lockout setting | Resistor-programmable threshold (1.2 V typ); opens FET if input drops below set point |
| 3 OVP | Overvoltage protection setting | Resistor-programmable cutoff threshold (1.2 V typ); disables output above set voltage |
| 4 SHDN | Shutdown control | Active-low digital input; pulls low to enter 12-µA shutdown mode and resets latched faults |
| 5 RTN | Reference ground | Internal reference node for UVLO, OVP, ILIM, dVdT; must be tied to system ground plane |
| 6 GND | System ground | Return path for FLT, SHDN, and internal logic; separate from RTN but electrically connected on PCB |
| 7 ILIM | Current limit programming | Resistor-to-RTN sets trip point (7.5 kΩ → 880 mA); supports single-point failure testing per UL 60950 |
| 8 dVdT | Slew rate control | Capacitor-to-RTN sets output ramp time (e.g., 22 nF → 11 ms); prevents inrush damage during hot-plug |
| 9 FLT | Fault indicator | Open-drain active-low flag signaling OCP, OVP, UVLO, or thermal shutdown |
| 10 OUT | Power output | Protected load-side rail; blocks reverse current up to –(60 – VIN) per TPS26625 specification |
Key Features
| Feature | Design Value |
|---|---|
| Dual reverse polarity protection | Simultaneous input (–60 V) and output (–(60 – VIN)) blocking eliminates need for external diodes or MOSFETs |
| Programmable slew rate control | dV/dt pin accepts 6.8–22 nF capacitor to tailor output ramp time (0.66–11 ms), enabling safe hot-swap insertion |
| Precision current limiting | ±5% accuracy at full-scale 880 mA ensures consistent trip behavior across temperature and unit variance |
| Fast short-circuit response | 220 ns typical fast-trip comparator delay isolates faults before energy dissipation damages downstream circuitry |
| IEC-compliant surge immunity | Meets IEC 61000-4-5 surge and IEC 61000-4-4 EFT standards with minimal external components |

FAQ
What is the maximum reverse voltage the TPS26625DRCT supports on its output pin?
The TPS26625DRCT supports output reverse polarity protection down to –(60 – VIN) volts. For example, at VIN = 24 V, it blocks reverse voltages as low as –36 V on the OUT pin. This capability is exclusive to TPS26624 and TPS26625 variants and enables safe operation during power-fail holdup conditions where output capacitors remain charged.
How does the TPS26625DRCT differ from the TPS26621DRCT in fault handling behavior?
The TPS26625DRCT and TPS26621DRCT both use auto-retry fault response, but only the TPS26625DRCT includes integrated output reverse polarity protection. The TPS26621DRCT provides input-side reverse protection only. Both share identical current limit adjustability, RON, and thermal shutdown thresholds-but TPS26625DRCT is required for applications needing bidirectional blocking.
Can the TPS26625DRCT be used in a 48-V telecom system with –48 V misconnection risk?
Yes-the TPS26625DRCT withstands –60 V on the IN pin and supports –(60 – VIN) on OUT, making it suitable for 48-V systems. With VIN = 48 V, it blocks –12 V on OUT and survives –48 V applied to IN. Its 0.3-µs reverse current blocking and UL 2367 recognition ensure compliance in telecom infrastructure where reverse battery events occur.
What external components are required to configure the TPS26625DRCT for 800-mA current limiting?
To set the TPS26625DRCT current limit to 800 mA, connect a 7.5-kΩ resistor between ILIM and RTN. A 22-nF capacitor between dVdT and RTN configures ~11-ms output ramp time. No additional TVS diodes or reverse-blocking MOSFETs are needed-the device integrates all core protection functions internally.
Does the TPS26625DRCT meet safety certifications required for industrial end equipment?
Yes-the TPS26625DRCT is UL 2367 recognized (File No. 169910) and IEC 62368-1 certified. These approvals validate its suitability for use in industrial machinery, factory automation, and building control systems where functional safety and fire-risk mitigation are mandated by regional regulatory bodies.
