HXY MOSFET · Supervisor And Reset ICs · SOP-8
MAX706ESA-HXY from HXY MOSFET, 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; pulling it low forces a reset. |
| 2 | VCC | power_in | Power supply input, with a 4.40V reset threshold on the 706 and a 4.8V to 5.5V supply range for the specified electrical characteristics. |
| 3 | GND | power_in | Ground. |
| 4 | PFI | input | Inverting input of the internal 1.25V comparator (threshold 1.25V typical); connect to GND or VCC when unused. |
| 5 | !PFO | output | Output of the internal 1.25V comparator. |
| 6 | WDI | input | Watchdog input; leaving it floating disables the watchdog function (watchdog timeout 1.6s typical). |
| 7 | !RESET | output | Active-low reset output, with a 200ms typical reset pulse width. |
| 8 | !WDO | output | Watchdog output. |
