RS706-2.63YK from Jiangsu RUNIC Tech, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | MR | input | Active-low Manual-Reset input. Triggers a reset pulse when pulled below 0.8V. Has an internal 20-120kΩ (52kΩ typ) pull-up; can be driven from TTL/CMOS logic or shorted to GND via a pushbutton. |
| 2 | VCC | power_in | Power supply voltage that is monitored. Operating range 1.0V to 5.5V; supply current 20µA typical, 40µA max. |
| 3 | GND | power_in | Ground reference for all signals. |
| 4 | PFI | input | Power-Fail comparator input. When PFI falls below the 1.2V (typ) threshold, PFO drives low. Connect to GND or VCC if not used. |
| 5 | PFO | output | Active-low Power-Fail output. Sinks current when PFI < 1.2V; otherwise stays high. Push-pull output (VOH ≥ 0.7×VCC at 800µA source; VOL ≤ 0.4V at 1.2mA sink). |
| 6 | WDI | input | Watchdog input. If WDI stays high or low for more than 1.6s (typ), the internal watchdog times out and WDO goes low. Floating WDI (or driving it to Hi-Z three-state) disables the watchdog. Watchdog timer clears on any rising or falling edge, or when WDI is three-stated. |
| 7 | RESET | output | Active-low reset output. Pulses low for 160ms after VCC rises above the 2.63V reset threshold or after MR goes high; remains low whenever VCC is below the threshold. Push-pull (VOH ≥ 0.7×VCC at 500µA source; VOL ≤ 0.4V at 1.2mA sink). Guaranteed valid down to VCC=1.0V. Watchdog timeout does not trigger RESET unless WDO is tied to MR. |
| 8 | WDO | output | Active-low watchdog output. Pulls low when the internal 1.6s (typ) watchdog count expires and does not go high again until the watchdog is cleared. Also goes low whenever VCC is below the reset threshold; has no minimum pulse width. Goes high with no delay after VCC rises above the reset threshold. |
