TPS26625DRCR Overview
An eFuse (electronic fuse) is a solid-state replacement for a traditional PTC fuse or Schottky OR-ing diode; instead of melting, it uses an internal MOSFET and control loop to limit current, assert FAULT, and either latch off or auto-retry. The TPS26625 specifically belongs to the auto-retry sub-family of TI's TPS2662x line, sitting within the broader hot-swap controller / power-path protection category of power-management ICs. Reverse-polarity protection on both input and output is integrated, removing the need for external blocking diodes or MOSFET bridges and reducing BOM cost, board area, and conduction losses.
Key features include 4.5-V to 60-V operating range (one device covers 12-V, 24-V and 48-V rails), 478-mΩ on-resistance, user-programmable undervoltage, overvoltage and current-limit thresholds, dedicated FLT and PG open-drain outputs, and selectable fault-response modes. The TPS26625 implements auto-retry after overcurrent or overtemperature events, while the TPS26624 in the same family latches off - a critical behavioral distinction for service vs. replaceable loads.
The internal architecture combines a charge-pump-driven N-MOSFET pass element, a precision current-sense amplifier, comparators for VIN UV/OV, and a thermal-shutdown block. Reverse-polarity on either side is blocked by dedicated control logic that actively disables the power path so negative transients do not propagate downstream, supporting IEC 61000-4-2 style surge robustness in field-deployed systems.
Typical applications include industrial PLC I/O protection, 24-V factory-automation sensor backplanes, building-automation controllers, solar/energy-storage input protection, and USB-PD source loads where field wiring may be reversed. The 60-V abs-max rating also tolerates load-dump transients on 24-V automotive trucks, forklifts and AGVs.
When designing in this part, prioritize thermal copper area: at 0.88 A continuous into a short circuit, the 478-mΩ FET dissipates up to ~0.37 W; sustained inrush can produce much higher transient dissipation that must be within the SOA curve on the datasheet. Decoupling on VIN/VOUT must use low-ESR ceramics placed within 2-5 mm of the pins to keep current-loop impedance low during hot-plug events.

Typical Applications
TPS26625DRCR is suitable for 7 applications: Industrial PLC I/O Backplane Protection, 24V Factory Sensor Power Rail, Building Automation / HVAC Controller, Solar / Energy-Storage Input Protection, USB-PD Source / 20V Sink Protection, Forklift / AGV 36V Battery Rail, Industrial 4G/5G Remote Terminal Unit.
Industrial PLC I/O Backplane Protection
The TPS26625DRCR's 60-V abs-max input range and integrated reverse-polarity blocks make it well-suited to protecting 24-V PLC backplanes from mis-wired field terminations. Its 0.025-0.88 A programmable current limit allows independent inrush management per I/O island, while the integrated 478 mΩ N-MOSFET eliminates a discrete blocking FET and its gate-drive components. FLT and PG outputs can drive the PLC CPU directly for diagnostic logging without an extra comparator.
Recommended
24V Factory Sensor Power Rail
A factory sensor bus often draws 0.1-0.4 A per node and runs from a long cable vulnerable to shorts and reverse wiring at installation time. The TPS26625DRCR's auto-retry fault recovery lets a momentary short clear itself without a service truck-roll, and its 0.025 A minimum programmable limit protects low-power sensor circuits that share the bus. The exposed thermal pad of the VSON-10 (DRC) package sinks ~2 W on a 1-square-inch copper pour, sufficient for sustained 0.88 A loads on a 24-V bus.
Recommended
Building Automation / HVAC Controller
Building-automation controllers routinely operate from 24 VAC rectified supplies subject to wiring errors. The TPS26625DRCR's input reverse-polarity block tolerates a backwards-wired transformer at install time, and its 4.5-V minimum operating voltage means the part still functions during a brown-out on a heavily loaded bus. The 478 mΩ RDS(on) keeps dissipation low even at the 0.88 A full-load setting, important inside a sealed thermostat housing without active cooling.
Recommended
Solar / Energy-Storage Input Protection
Energy-storage inputs and small PV converters see frequent reverse-polarity events during installation and service. The TPS26625DRCR's 60-V abs-max and integrated reverse-polarity block on both VIN and VOUT make it a compact safeguard; its OV/UV programmability lets designers trip on a 30-V overcharge threshold without an external supervisor. The wide temperature range of -40 °C to +125 °C handles outdoor cabinet environments over a full year.
Recommended
USB-PD Source / 20V Sink Protection
USB-PD sources that negotiate up to 20 V at 0.88 A sit well within the TPS26625DRCR's operating range, and the integrated reverse-polarity block defends against mis-inserted Type-C cabling accessory faults. The device's fast current-loop response (microseconds, per TI TPS2662 datasheet) limits inrush at Type-C attach. Designers should add a downstream PTC or TVS to clamp ESD that bypasses the eFuse's protection envelope.
Recommended
Forklift / AGV 36V Battery Rail
Forklift and AGV systems use 36-V lead-acid batteries subject to load-dump transients and field-reversed replacement packs. The TPS26625DRCR blocks reverse polarity on both VIN and VOUT during a battery swap, while the 60-V abs-max gives margin for brief load-dump spikes. Auto-retry behavior lets the controller survive a momentary short and resume without intervention - critical for an autonomous vehicle that may be far from a service bay.
Recommended
Industrial 4G/5G Remote Terminal Unit
Remote terminal units (RTUs) at cell-tower base stations or pipeline sites draw from a 24-48 V bus where the wiring can be reversed during installation. The TPS26625DRCR's integrated reverse-polarity block at 24-48 V nominal plus 60-V abs-max gives margin for the 58-V telecom surge profile while eliminating a discrete blocking diode. The 478 mΩ RDS(on) keeps full-load dissipation to roughly 0.42 W at 0.88 A - manageable inside a sealed outdoor enclosure with no forced cooling.

Key Differentiators
- Auto-retry behavior on OC and OT faults (vs TPS26624DRCR)
- 0.88 A max current limit in same VSON-10 footprint (vs TPS26623DRCR)
- Highest current limit in the auto-retry sub-family (vs TPS26621DRCR)
- Integrated input and output reverse-polarity protection (vs MAX17613BATP+T)
Design Notes
Estimated: at the 0.88 A full-current-limit setting and 24-V input with a 5-V shorted output, the integrated MOSFET dissipates 19 V * 0.88 A ≈ 16.7 W during the fault. Continuous fault (latch-off or auto-retry) demands substantial copper: TI's TPS2662 datasheet shows the 10-pin VSON (DRC) thermal pad needs ≥1 square inch of 2-oz copper to keep junction rise below 100 °C. Add thermal vias under the EP and de-rate ILIM to 0.5 A or lower if the board cannot host this copper area.
Place VIN and VOUT decoupling ceramic capacitors within 5 mm of the respective pins to keep the hot-plug current loop as small as possible - a wide loop creates parasitic inductance that sees 10-30 V transients during VBUS attach. Use X7R 10 nF + 1 µF in parallel on VIN and a single 22 µF X7R on VOUT. The ILIM resistor must be located within 2-3 mm of pin 5 to avoid stray capacitance that degrades the current-loop response.
Do not size ILIM below the steady-state load current - the eFuse's slow-trip threshold tracks the DC load while the fast-trip handles inrush. If you accidentally set ILIM below the nominal load, the part will false-trip during warm-up. Also remember that reverse-polarity protection works only when VIN is within the 4.5-V to 60-V envelope; below 4.5 V the charge pump UVLO disables reverse-block but does not harm the IC (per TPS2662 datasheet fault table).
The exposed thermal pad (EP) is the primary heat path - solder it to a continuous ground plane with at least 9 thermal vias on a 3x3 grid (0.3 mm drill, 0.6 mm pitch). Route high-current VIN and VOUT planes directly under the package rather than relying on traces. Keep the FLT and PG traces short; if used in noisy environments add 100 kΩ pull-ups close to the IC because these are open-drain outputs that can pick up fast transients.
Although the eFuse is a relatively slow device (kHz current-loop bandwidth), the high dv/dt at hot-plug and the 478 mΩ MOSFET body can still couple switching noise into adjacent analog circuits. Add a ferrite bead in series with VIN when the upstream supply is a switching DC-DC converter. Avoid running analog sensor traces under the part; keep ≥3 mm clearance or use a guard ground trace.
