# FPF2004

**onsemi** · AC-DC Controllers And Regulators · SC-70-5

FPF2004 from onsemi, in a SC-70-5. 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 | VOUT | power_out | Output of the power switch, a 0.7 Ω current-limited P-channel MOSFET; VOUT must not be driven above VIN because reverse voltage can cause large currents and permanent damage, and VIN, VOUT, ON and FLAGB are rated −0.3 V to 6 V to GND. |
| 2 | GND | power_in | Ground reference for the device; all voltage ratings (VIN, VOUT, ON, FLAGB) are specified relative to GND. |
| 3 | FLAGB | output | Active-LO open-drain fault output that indicates over-current, supply under-voltage or over-temperature and requires a pull-up resistor between VIN and FLAGB; rated −0.3 V to 6 V to GND. |
| 4 | ON | input | On control input that turns the switch on (Active HI or Active LO depending on the ordering version), with VIL at most 0.5 V at VIN = 1.8 V and 0.9 V at VIN = 5.5 V, VIH at least 0.8 V at 1.8 V and 1.5 V at 5.5 V, and an absolute maximum of 6 V to GND. |
| 5 | VIN | power_in | Input to the power switch and the supply voltage for the IC, specified for 1.8 V to 5.5 V operation with an absolute maximum of 6 V to GND. |

## CAD (KiCad official)

- Symbol: `FPF2004`
- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`
- 3D model: SC-70-5 (KiCad packages3D, STEP)
- 3D model files: `fpf2004-etched.step` / `fpf2004-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `fpf2004.step` / `fpf2004.glb` are the bare package body.
