HXY MOSFET · Supervisor And Reset ICs · SOP-8
MAX708ESA-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 internal 20kΩ (10-40kΩ) pull-up; VIH 2.0V min and VIL 0.8V max at 4.5V<VCC<5.5V. |
| 2 | VCC | power_in | Power supply input; operating range 1.1V/1.2V to 5.5V, with reset threshold of 4.40V for the 708. |
| 3 | GND | power_in | Ground. |
| 4 | PFI | input | Inverting input of the internal 1.25V power-fail comparator (threshold 1.25V typ); connect to GND or VCC when unused. |
| 5 | !PFO | output | Output of the internal 1.25V power-fail comparator, sinks 3.2mA at VOL ≤0.4V (4.5V<VCC<5.5V). |
| 6 | NC | unconnected | No connection. |
| 7 | !RESET | output | Active-low reset output, 200ms typical reset pulse width, sinks 3.2mA at VOL ≤0.4V (4.5V<VCC<5.5V). |
| 8 | RESET | output | Active-high reset output, inverse of !RESET, 200ms typical reset pulse width. |
