CN706T

ShangHai Consonance Elec · Supervisor and Reset ICs · SOP-8

CN706T from ShangHai Consonance Elec, in a SOP-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. Internally pulled up to VCC; pulling MR below the input-low threshold (~0.8V at VCC=5V) asserts RESET. TTL/CMOS compatible; can be driven by a pushbutton to GND.
2 VCC power_in Positive supply input. Operating range 1.15V to 5.5V; typical operating current 52uA at VCC=5V. Absolute maximum 6.0V.
3 GND power_in Ground return, 0V reference for all signals.
4 PFI input Power-fail comparator non-inverting input. Compared against an internal 1.22V reference; when PFI drops below 1.22V, PFO is asserted low. High-impedance input (IPFI ~ 0). Tie to GND or VCC if unused.
5 PFO output Active-low power-fail comparator output. Driven low when PFI < 1.22V; push-pull output, VOH = VCC-1.2V at 800uA source, VOL = 0.3V at 3.2mA sink.
6 WDI input Watchdog input. Must be toggled within the 1.6s watchdog timeout window (tWD); if left static high or low longer than tWD, WDO is asserted low and a reset pulse is generated. Three-state internally to allow floating disable of the watchdog.
7 RESET output Active-low reset output. Asserted low when VCC falls below the 3.08V reset threshold (VRES), when MR is pulled low, or on watchdog timeout; remains low for tRES = 200ms (typ) after VCC recovers above VRES. Guaranteed valid down to VCC = 1.0V.
8 WDO output Active-low watchdog output. Driven low when WDI has not been toggled within the 1.6s watchdog timeout window; push-pull output, VOH = VCC-1.2V at 800uA source, VOL = 0.3V at 3.2mA sink.

Two STEP files. Same geometry, different body top:

File Size Use it when
cn706t.step 122 KB You want the bare part, or you mark your own boards.
cn706t-etched.step 1.3 MB You want the part with CN706T already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 338 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
