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 | RESET | output | Active-low open-drain reset output. Driven low when SENSE drops below VIT (3.07 V typ) or MR is pulled low; released high after the programmed reset delay once SENSE is above VIT and MR is high. Requires a 10 kΩ to 1 MΩ pull-up (may pull to a rail higher than VDD). Max IRESET = 5 mA. |+| 2 | GND | power_in | Device ground reference. |+| 3 | MR | input | Active-low manual reset input. Driving this pin low asserts RESET. Internally pulled to VDD through a ~90 kΩ resistor (70 kΩ min), so it may be left floating if unused. VIL ≤ 0.3·VDD, VIH ≥ 0.7·VDD. |+| 4 | CT | input | Reset-delay programming pin. Leaving open selects the fixed 20 ms delay; tying to VDD via a 40 kΩ resistor selects 300 ms; connecting a ground-referenced capacitor ≥100 pF programs a user delay of 1.25 ms to 10 s. Input capacitance ~5 pF. |+| 5 | SENSE | input | Voltage-sense input connected to the monitored supply. RESET is asserted when this pin drops below the threshold voltage VIT (3.07 V typical for the G33 option). Very high input impedance; ISENSE ≤ 25 nA. Recommended range 0 V to VDD. |+| 6 | VDD | power_in | Supply voltage, 1.8 V to 6.5 V (absolute max 7 V). Typical IDD = 2.4 µA at 3.3 V. Bypass with a 0.1 µF ceramic capacitor close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `TPS3808G33QDBVRQ1`+- `TPS3808G33QDBVRQ1QDRVRQ1`++## CAD (KiCad official)++- Symbol: `TPS3808G33QDBVRQ1`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (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/tps3808g33qdbvrq1.pdf) (27 pp, sha256 `f3419820453e5366`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
