**lingxingic** · Supervisor And Reset ICs · SOP-8

MAX708SESA 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 | Hardware reset input, active low; it requires a high-level input voltage of at least 2 V and a low-level input voltage of at most 0.8 V, with a low-level input current of 100 to 600 uA at 0 V. |
| 2 | VDD | power_in | Supply pin with a supply voltage range of 1 V to 5.5 V, referenced to GND. |
| 3 | GND | power_in | Ground reference pin for all voltages in the device. |
| 4 | PFI | input | Independent voltage detection input, compared against an internal 1.25 V reference (VTP 1.20 V to 1.30 V) with an input current of at most 0.1 uA. |
| 5 | PFON | output | Independent voltage detection result output, high when PFI is above 1.25 V; it outputs at least 3.5 V at -800 uA and at most 0.4 V at 3.2 mA. |
| 6 | NC | unconnected | No internal connection; this pin is left empty. |
| 7 | RESETN | output | Power-supply monitor reset output, active low; it outputs at least 3.5 V at -800 uA and at most 0.4 V at 3.2 mA, and is valid when VDD exceeds 1 V. |
| 8 | RESET | output | Power-supply monitor reset output, active high; it outputs at least 3.5 V at -800 uA and at most 0.4 V at 3.2 mA, and is valid when VDD exceeds 1 V. |
