MAX813LESA+T from Analog Devices Inc Maxim Integrated, 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 | Active-low manual-reset input that triggers a reset pulse when pulled below 0.8V, with an internal 250µA pullup, and can be driven by TTL/CMOS logic or shorted to ground with a switch. |
| 2 | VCC | power_in | +5V supply input; the datasheet specifies an operating voltage range of 1.1V to 5.5V for MAX813LC and 1.2V to 5.5V for MAX813LE/M. |
| 3 | GND | power_in | 0V ground reference for all signals. |
| 4 | PFI | input | Power-fail voltage-monitor input; when PFI is below 1.25V, PFO goes low, and PFI should be connected to GND or VCC when not used. |
| 5 | PFO | output | Power-fail output goes low and sinks current when PFI is below 1.25V; otherwise it stays high. |
| 6 | WDI | input | Watchdog input; if WDI remains high or low for 1.6s the watchdog timer runs out and WDO goes low, while floating or three-stating WDI disables the watchdog feature. |
| 7 | RESET | output | Active-high reset output that is the inverse of RESET, guaranteed valid down to VCC = 1.1V (MAX813LC) and with a 200ms minimum reset pulse width. |
| 8 | WDO | output | Watchdog output pulls low when the internal watchdog timer finishes its 1.6s count and stays low during low-line conditions, with no minimum pulse width and going high with no delay once VCC rises above the reset threshold. |
