CN706P

ShangHai Consonance Elec · Monitors & Reset Circuits · SOP-8

CN706P from ShangHai Consonance Elec, 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: a low level triggers a reset pulse, the pin has an internal pull-up and may be left floating, and it is compatible with TTL/CMOS levels.
2 VCC power_in Positive power supply input.
3 GND power_in Power supply ground input.
4 PFI input Power-fail detection input: when the voltage on this pin falls below 1.22 V, PFO is driven low; if unused it may be tied to VCC or GND.
5 PFO output Power-fail detection output: it goes low when the PFI voltage is below 1.22 V and is high otherwise.
6 WDI input Watchdog input: if the level stays high or low for longer than 1.6 s the watchdog timer expires and WDO goes low; floating or tying this pin to a high-impedance node disables the watchdog.
7 RESET output Active-low reset output: held low while VCC is below the reset threshold, then held low for 200 ms after VCC rises above the threshold, and then goes high.
8 WDO output Watchdog output: goes low when the watchdog timer completes its 1.6 s timeout and stays low until the timer is reset, and also goes low while VCC is below the reset threshold.
