# TPS3839L30DQNR

**Texas Instruments** · Supervisor And Reset ICs · X2SON-4(1x1)

TPS3839L30DQNR from Texas Instruments, in a X2SON-4(1x1). 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 | RESET | output | Active-low reset output with push-pull drive; low while VDD < 2.63 V threshold and for 200 ms (typ) after VDD rises above threshold. |
| 2 | NC | unconnected | No internal connection. |
| 3 | GND | power_in | Ground. |
| 4 | VDD | power_in | Supply voltage input, operating range 0.9 V to 6.5 V, 150 nA (typ) supply current. |
| 5 | Thermal pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

## CAD (KiCad official)

- Symbol: `TPS3839L30DQNR`
- Footprint: `Package_SON:Texas_X2SON-4_1x1mm_P0.65mm`
- 3D model: X2SON-4(1x1), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.4 mm nominal X2SON height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `tps3839l30dqnr-etched.step` / `tps3839l30dqnr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps3839l30dqnr.step` / `tps3839l30dqnr.glb` are the bare package body.
