MAX706TESA from lingxingic, in a SOP-8. 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 | MRN | input | Active-low hardware reset input; holding it low holds RESETN low and resets the watchdog, with MRN low-level input voltage at most 0.8 V and high-level input voltage at least 3 V (VDD=5 V). |
| 2 | VDD | power_in | Supply voltage, 1 V to 5.5 V recommended (absolute maximum -0.3 V to 6.0 V); RESETN is valid for VDD above 1 V. |
| 3 | GND | power_in | Ground reference; all voltages are referenced to this pin. |
| 4 | PFI | input | Independent voltage detection input compared against an internal 1.25 V reference (1.20 V to 1.30 V), with input current at most 0.1 µA over 0 to VDD. |
| 5 | PFON | output | Independent voltage detection output that goes high when PFI is above 1.25 V and low when it is below; VOH at least 3.5 V at 800 µA and VOL at most 0.4 V at 3.2 mA. |
| 6 | WDI | input | Watchdog input; any rising or falling edge restarts the watchdog timer, a level held for about 1.6 s (typical) lets it time out, and leaving it floating disables the watchdog (VIH at least 3.5 V, VIL at most 0.8 V). |
| 7 | RESETN | output | Active-low power-supply reset output that goes low when VDD falls below the selected threshold VT and goes high about 200 ms (typical) after VDD rises above VT; it cannot guarantee a valid low below 1 V, so a 100 kΩ pull-down is recommended in that range. |
| 8 | WDON | output | Watchdog output that is high while WDI is toggling with RESETN high and goes low on watchdog timeout or during reset; VOH at least 3.5 V at 800 µA and VOL at most 0.4 V at 1.2 mA. |
