MSKSEMI · Supervisor And Reset ICs · SOP-8
MAX706SCSA from MSKSEMI, 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 | !MR | input | Manual reset input, with an internal 20kΩ typical pull-up (10 to 40kΩ). |
| 2 | VCC | power_in | Supply voltage; the 706S operates from 3.3V to 5.5V and its reset threshold is 2.93V typical. |
| 3 | GND | power_in | Ground. |
| 4 | PFI | input | Inverting input of the internal 1.25V comparator (power-fail threshold 1.25V typical). |
| 5 | !PFO | output | Output of the internal 1.25V comparator. |
| 6 | WDI | input | Watchdog input; leaving it floating disables the watchdog function (1.6s typical timeout). |
| 7 | !RESET | output | Active-low reset signal output, with a 200ms typical reset pulse width. |
| 8 | !WDO | output | Watchdog output. |
