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 to a low-impedance state whenever SENSE is below V_IT (3.07 V typ for the G33 option) or MR is low; released to high-Z after the user-programmed reset delay expires. Requires an external pull-up resistor of 10 kΩ to 1 MΩ; the pin may be pulled above V_DD (up to 6.5 V). I_RESET max = 5 mA (absolute max). |+| 2 | GND | power_in | Device ground reference. |+| 3 | MR | input | Active-low manual reset input. Driving MR low (V_IL ≤ 0.3·V_DD) asserts RESET; MR must return above V_IH (≥ 0.7·V_DD) for RESET to release after the delay. Internally pulled up to V_DD through a ~90 kΩ resistor (70-110 kΩ), so the pin may be left unconnected if unused. Minimum input pulse width: 1 μs. |+| 4 | CT | passive | Reset delay-time programming pin. Leave open for the fixed 20 ms delay, tie to V_DD (through 40 kΩ-200 kΩ) for the fixed 300 ms delay, or connect a ground-referenced capacitor ≥ 100 pF to program a user delay from 1.25 ms (100 pF) to 10 s (180 nF). Absolute-max voltage: −0.3 V to V_DD + 0.3 V. |+| 5 | SENSE | input | Voltage-monitor input. Connected internally to a precision comparator (0.5% typ threshold accuracy for V_IT ≤ 3.3 V); when the SENSE voltage drops below V_IT (3.07 V typ on the G33 option), RESET is asserted. Input current is 1.7 μA typ at V_SENSE = 6.5 V. A 1 nF-10 nF bypass to GND is recommended to reduce transient sensitivity. |+| 6 | VDD | power_in | Supply voltage input. Operating range 1.65 V to 6.5 V (1.7-6.5 V over full −40 °C to +125 °C range); I_DD = 2.4 μA typ at V_DD = 3.3 V. A 0.1 μF ceramic bypass capacitor close to the pin is recommended. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `TPS3808G33DBVRDBVR`+- `TPS3808G33DBVRDBVT`+- `TPS3808G33DBVRDRVR`+- `TPS3808G33DBVRDRVT`++## CAD (KiCad official)++- Symbol: `TPS3808G33DBVR`+- 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/tps3808g33.pdf) (24 pp, sha256 `52446728d1e14cef`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
