Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | IN | power_in | Power input to the eFuse; the operating input range is 2.7 V to 24 V, with an absolute maximum of 30 V. |+| 2 | IN | power_in | Power input to the eFuse; the operating input range is 2.7 V to 24 V, with an absolute maximum of 30 V. |+| 3 | IN | power_in | Power input to the eFuse; the operating input range is 2.7 V to 24 V, with an absolute maximum of 30 V. |+| 4 | GND | power_in | Ground connection to the system ground, used as the reference for all internal signals. |+| 5 | GND | power_in | Ground connection to the system ground, used as the reference for all internal signals. |+| 6 | EN/UVLO | input | Active-high enable with an external resistor divider from IN to GND to set the UVLO threshold; it must not be left floating and its absolute maximum is 7 V. |+| 7 | ITIMER | output | A capacitor to GND sets the overcurrent blanking interval; leave it open for the fastest response, and shorting it to GND triggers a device fault. |+| 8 | ILIM | output | A resistor to GND sets the output current-limit and fast-trip thresholds; the recommended RILIM range is 82 Ω to 1650 Ω and the pin must not be left floating. |+| 9 | IMON | output | Analog load-current monitor output that sources current proportional to the load current (gain 246 µA/A typical); a resistor to GND converts it to a voltage. |+| 10 | RETRY_DLY | output | A capacitor to GND sets the delay before an automatic restart attempt after a fault; connecting this pin to GND selects latch-off with no auto-retry. |+| 11 | NRETRY | output | A capacitor to GND sets the number of automatic restart attempts after a fault; connecting this pin to GND selects infinite retries. |+| 12 | LDSTRT | input | Load-detect/handshake input where a capacitor to GND sets the time window in which the load must pull this pin low after PG asserts; connect to GND if unused and do not leave it floating. |+| 13 | PG | output | Active-high power-good open-drain output that requires an external pull-up, is asserted when the FET is fully enhanced and the output reaches its maximum voltage, and is held low when VIN is below VUVP. |+| 14 | GND | power_in | Ground connection to the system ground, used as the reference for all internal signals. |+| 15 | dVdt | output | A capacitor to GND sets the output turn-on slew rate; leave it open for the fastest slew rate during startup. |+| 16 | IN | power_in | Power input to the eFuse; the operating input range is 2.7 V to 24 V, with an absolute maximum of 30 V. |+| 17 | OUT | power_out | Power output to the load; the device can carry a continuous switch current of up to 15 A from IN to OUT. |+| 18 | OUT | power_out | Power output to the load; the device can carry a continuous switch current of up to 15 A from IN to OUT. |+| 19 | OUT | power_out | Power output to the load; the device can carry a continuous switch current of up to 15 A from IN to OUT. |+| 20 | OUT | power_out | Power output to the load; the device can carry a continuous switch current of up to 15 A from IN to OUT. |+| 21 | OUT | power_out | Power output to the load; the device can carry a continuous switch current of up to 15 A from IN to OUT. |+| 22 | OUT | power_out | Power output to the load; the device can carry a continuous switch current of up to 15 A from IN to OUT. |+| 23 | OUT | power_out | Power output to the load; the device can carry a continuous switch current of up to 15 A from IN to OUT. |+| 24 | OUT | power_out | Power output to the load; the device can carry a continuous switch current of up to 15 A from IN to OUT. |+| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | VQFN-24(4x4) |+| Category | Power Management (PMIC) |+| Pins | 25 |++## CAD (KiCad official)++- Symbol: `TPS259824LNRGER`+- Footprint: `Package_DFN_QFN:QFN-24-1EP_4x4mm_P0.5mm_EP2.7x2.7mm`+- 3D model: VQFN-24(4x4) (KiCad packages3D, STEP)+- 3D model files: `tps259824lnrger-etched.step` / `tps259824lnrger-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps259824lnrger.step` / `tps259824lnrger.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/tps25982) (55 pp, sha256 `f4a0f06cfbd81f26`, retrieved 2026-10-08, tier: lcsc)+- **Datasheet language:** Chinese.
