Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | DMODE | input | Diode Mode control pin. A logic high activates the non-ideal diode mode, blocking reverse current flow from OUT to IN. |+| 2 | PGOOD | output | Active-high open-drain power-good indicator. Asserts high when PGTH has crossed its threshold, indicating output is in regulation. Requires an external pull-up resistor. |+| 3 | PGTH | input | Positive input of the PGOOD comparator. Typically driven from a resistor divider off VOUT to set the power-good threshold. |+| 4 | OUT | power_out | Power output of the device (drain of internal back-to-back FETs). Pins 4-8 are internally tied and must all be connected for 5 A rated current. |+| 5 | OUT | power_out | Power output of the device. Tie together with pins 4, 6, 7, 8. |+| 6 | OUT | power_out | Power output of the device. Tie together with pins 4, 5, 7, 8. |+| 7 | OUT | power_out | Power output of the device. Tie together with pins 4, 5, 6, 8. |+| 8 | OUT | power_out | Power output of the device. Tie together with pins 4-7. |+| 9 | IN | power_in | Power input and supply voltage, 2.7 V to 18 V (20 V max). Pins 9-13 are internally tied and must all be connected for 5 A rated current. |+| 10 | IN | power_in | Power input and supply voltage. Tie together with pins 9, 11, 12, 13. |+| 11 | IN | power_in | Power input and supply voltage. Tie together with pins 9, 10, 12, 13. |+| 12 | IN | power_in | Power input and supply voltage. Tie together with pins 9, 10, 11, 13. |+| 13 | IN | power_in | Power input and supply voltage. Tie together with pins 9-12. |+| 14 | EN/UVLO | input | Enable / programmable undervoltage lockout input. A resistor divider from VIN sets the UVLO threshold; a UV event opens the internal FET and asserts /FLT. Pulling to GND resets the fault latch on TPS25942L / TPS25944L. |+| 15 | OVP | input | Programmable overvoltage protection threshold input. Set with a resistor divider from VIN; an OV event opens the internal FET and asserts /FLT. |+| 16 | GND | power_in | Device ground reference. Must be connected to the exposed PowerPAD. |+| 17 | ILIM | passive | Current-limit programming pin. A resistor from ILIM to GND (R_ILIM ≥ 20 kΩ, 4.81 A max) sets the overload and short-circuit current limit (0.6 A to 5.3 A ±8%). |+| 18 | dVdT | passive | Output slew-rate programming pin. A capacitor from dVdT to GND sets the ramp rate of the output voltage during turn-on / hot-plug. |+| 19 | IMON | output | Analog current monitor output. Sources a scaled-down replica (±8%) of the current flowing through the internal FET; a resistor to GND converts it to a proportional voltage. |+| 20 | /FLT | output | Active-low open-drain fault indicator. Asserts on undervoltage, overvoltage, reverse voltage, circuit-breaker timeout (TPS25944 only), and thermal shutdown. Requires an external pull-up resistor. |+| PAD | PowerPAD | power_in | Exposed thermal pad on package bottom. Must be tied to GND (pin 16) and connected to the PCB ground plane through multiple thermal vias for rated thermal performance. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | QFN-20-EP(3x4) |+| Category | PMIC |+| Pins | 21 |++## Ordering variants++- `TPS25942ARVCR`+- `TPS25942ARVCRRVCT`++## CAD (KiCad official)++- Symbol: `TPS25942ARVCR`+- Footprint: `Package_DFN_QFN:QFN-20-1EP_3x4mm_P0.5mm_EP1.65x2.65mm`+- 3D model: QFN-20-EP(3x4) (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/tps25942arvcr.pdf) (56 pp, sha256 `11ee4de5549f6957`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
