MAX706PESA-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 (10-40kΩ) pull-up; input thresholds are 2.0V/0.8V for 4.5V<VCC<5.5V. |
| 2 | VCC | power_in | Power supply input; the 706P/R operates with VCC of 3.0V to 5.5V and its reset threshold is 2.63V. |
| 3 | GND | power_in | Ground. |
| 4 | PFI | input | Inverting input of the internal 1.25V power-fail comparator (1.25V threshold); connect to GND or VCC when unused. |
| 5 | !PFO | output | Output of the internal 1.25V power-fail comparator. |
| 6 | WDI | input | Watchdog input (1.6s typical timeout); leaving it floating disables the watchdog function. |
| 7 | RESET | output | Active-high reset output (706P), the inverse of !RESET, with a 200ms typical reset pulse width. |
| 8 | !WDO | output | Watchdog output. |
