@@ -0,0 +1,54 @@+# TPS25925++**Texas Instruments** · eFuse · VSON-10++Integrated electronic fuse that sits in a supply rail and protects the load from overcurrent, overvoltage, and inrush. An internal FET limits current to a level set by one resistor at ILIM, a capacitor at dV/dT ramps the output to tame inrush on hot-plug, and EN/UVLO sets the turn-on threshold, with a thermal shutdown backing it all up. It works on a 2.7 to 18 V rail, so it guards USB, hot-swap, and module power inputs. A one-chip replacement for a fuse plus a supervisor plus a MOSFET.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | dV/dT | input | Slew-rate programming pin. A capacitor from this pin to GND sets the ramp rate of OUT at device turn-on. |+| 2 | EN/UVLO | input | Dual-function enable / UVLO pin. Pulling low shuts off the internal pass MOSFET; pulling high enables the device. An external resistor divider from VIN sets a custom UVLO trip point. |+| 3 | VIN | power_in | Input supply voltage (nominal 5 V for TPS25925x; absolute max 20 V DC / 22 V transient). |+| 4 | VIN | power_in | Input supply voltage (nominal 5 V for TPS25925x; absolute max 20 V DC / 22 V transient). |+| 5 | VIN | power_in | Input supply voltage (nominal 5 V for TPS25925x; absolute max 20 V DC / 22 V transient). |+| 6 | OUT | power_out | Protected output of the internal pass MOSFET (30 mΩ typical Rds(on)). Rated for continuous 6.25 A output current. |+| 7 | OUT | power_out | Protected output of the internal pass MOSFET (30 mΩ typical Rds(on)). Rated for continuous 6.25 A output current. |+| 8 | OUT | power_out | Protected output of the internal pass MOSFET (30 mΩ typical Rds(on)). Rated for continuous 6.25 A output current. |+| 9 | NC | unconnected | Not connected internally. May be left floating or tied to GND. |+| 10 | ILIM | input | Current-limit programming pin. A resistor from this pin to GND sets the overload and short-circuit current limit (2-5 A range, ±15% accuracy). |+| 11 | GND | power_in | Exposed thermal pad. Serves as the device ground reference and the primary thermal path; must be soldered to the PCB GND plane. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | eFuse (integrated protection switch) |+| Input | 2.7-18 V |+| Current limit | Adjustable via ILIM resistor |+| Inrush control | Adjustable via dV/dT capacitor |+| Enable/UVLO | Programmable threshold (EN/UVLO) |+| Protection | Overcurrent, thermal shutdown |+| Package | VSON-10 |++## Ordering variants++- `TPS25925xDRC (VSON-10)`+- `TPS25921x / TPS25940x (family variants)`++## CAD (KiCad official)++- Symbol: `Power_Management:TPS2592xx (KiCad official)`+- Footprint: `Package_SON:VSON-10-1EP_3x3mm_P0.5mm_EP1.65x2.4mm_ThermalVias`+- 3D model: VSON-10 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tps25925.pdf) (36 pp, sha256 `959aa0f67322ab34`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
