# TPS3707-33DGNR

**Texas Instruments** · Supervisor And Reset ICs · MSOP-8-EP

TPS3707-33DGNR from Texas Instruments, in a MSOP-8-EP. 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 for the TPS3707-xx DGN package, per the pin-function table (overbar lost in text extraction, so polarity is taken from the table's 'Active-low reset output' label). |
| 2 | RESET | output | Active-high reset output for the TPS3707-xx DGN package, per the pin-function table. |
| 3 | MR | input | Manual reset input; logic-high threshold is 0.7 × VDD minimum and logic-low threshold is 0.3 × VDD maximum, with input rise and fall rate limited to 100 ns/V maximum. |
| 4 | VDD | power_in | Supply voltage, recommended operating range 2 V to 6 V, with absolute maximum of 7 V referenced to GND. |
| 5 | GND | power_in | Ground reference; all device voltage values are specified with respect to GND. |
| 6 | PFI | input | Power-fail comparator input, with voltage range from −0.3 V to VDD + 0.3 V. |
| 7 | PFO | output | Power-fail comparator output that signals a power-fail or low-battery warning condition. |
| 8 | NC | unconnected | No internal connection on the TPS3707-xx DGN package. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

## CAD (KiCad official)

- Symbol: `TPS3707-33DGNR`
- Footprint: `Package_SO:MSOP-8-1EP_3x3mm_P0.65mm_EP1.5x1.8mm`
- 3D model: MSOP-8-EP (KiCad packages3D, STEP)
- 3D model files: `tps3707-33dgnr-etched.step` / `tps3707-33dgnr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps3707-33dgnr.step` / `tps3707-33dgnr.glb` are the bare package body.
