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 when reset is asserted and remains asserted for the programmed delay after both SENSE rises above VIT and MR returns high. Requires an external pull-up (10kΩ to 1MΩ); the pull-up may be tied to a rail higher than VDD (up to 6.5V). Guaranteed VOL 0.3V @ IOL=0.4mA (1.3V<=VDD<1.8V) or 0.4V @ IOL=1.0mA (1.8V<=VDD<=6.5V); leakage <=300nA when not asserted. |+| 2 | GND | power_in | Device ground reference (0 V). |+| 3 | MR | input | Active-low manual reset input. Driving MR below 0.3*VDD asserts RESET; MR must return above 0.7*VDD to clear. Internally pulled up to VDD by a ~90kΩ (70k min) resistor, so the pin can be left floating if unused. Do not apply voltage above VDD. |+| 4 | CT | passive | Reset-delay programming pin. Three modes: (a) leave open -> fixed 20ms delay; (b) tie to VDD through 40k-200kΩ -> fixed 300ms delay; (c) tie an external capacitor (>=100pF) from CT to GND -> user-programmable delay 1.25ms-10s per CT(nF)=[tD(s)-0.5e-3]x175. Charged by an internal 220nA source to 1.23V. Absolute range -0.3V to VDD+0.5V; use low-leakage (ceramic) capacitors. |+| 5 | SENSE | input | Voltage-monitor input. RESET asserts when SENSE drops below the negative-going threshold VIT (0.405V typ on the G01 adjustable variant); the comparator has ~1.5% VIT hysteresis. Input current ±25nA max on G01. Recommended to add a 1nF-10nF bypass capacitor for noise immunity. Absolute range -0.3V to +7V. |+| 6 | VDD | power_in | Supply voltage, 1.7V to 6.5V (absolute max 7.0V). Typical quiescent current ~2.8µA at 3.3V. Place a 0.1µF ceramic decoupling capacitor close to this pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `PT7M3808G01TAEXTAEX`+- `PT7M3808G01TAEXTA`+- `PT7M3808G01TAEXZC`++## CAD (KiCad official)++- Symbol: `PT7M3808G01TAEX`+- 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:** [Diodes Incorporated datasheet](https://www.diodes.com/assets/Datasheets/PT7M3808G01TAEX.pdf) (13 pp, sha256 `56de409e252a0b54`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
