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 | MR | input | Active-low manual reset input. Internally pulled up to VCC; pulling MR below the input-low threshold (~0.8V at VCC=5V) asserts RESET. TTL/CMOS compatible; can be driven by a pushbutton to GND. |+| 2 | VCC | power_in | Positive supply input. Operating range 1.15V to 5.5V; typical operating current 52uA at VCC=5V. Absolute maximum 6.0V. |+| 3 | GND | power_in | Ground return, 0V reference for all signals. |+| 4 | PFI | input | Power-fail comparator non-inverting input. Compared against an internal 1.22V reference; when PFI drops below 1.22V, PFO is asserted low. High-impedance input (IPFI ~ 0). Tie to GND or VCC if unused. |+| 5 | PFO | output | Active-low power-fail comparator output. Driven low when PFI < 1.22V; push-pull output, VOH = VCC-1.2V at 800uA source, VOL = 0.3V at 3.2mA sink. |+| 6 | WDI | input | Watchdog input. Must be toggled within the 1.6s watchdog timeout window (tWD); if left static high or low longer than tWD, WDO is asserted low and a reset pulse is generated. Three-state internally to allow floating disable of the watchdog. |+| 7 | RESET | output | Active-low reset output. Asserted low when VCC falls below the 3.08V reset threshold (VRES), when MR is pulled low, or on watchdog timeout; remains low for tRES = 200ms (typ) after VCC recovers above VRES. Guaranteed valid down to VCC = 1.0V. |+| 8 | WDO | output | Active-low watchdog output. Driven low when WDI has not been toggled within the 1.6s watchdog timeout window; push-pull output, VOH = VCC-1.2V at 800uA source, VOL = 0.3V at 3.2mA sink. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | ShangHai Consonance Elec |+| Package | SOP-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `CN706TS`+- `CN706TP`++## CAD (KiCad official)++- Symbol: `CN706T`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [ShangHai Consonance Elec datasheet](docs/cn706t-datasheet.pdf) (14 pp, sha256 `fe7cca14ea02af6e`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
