CBM706PAS8

Corebai Microelectronics · Supervisor And Reset ICs · SOIC-8

CBM706PAS8 from Corebai Microelectronics, in a SOIC-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: when taken below 0.6 V a reset is generated, it is internally debounced, and an internal 70 µA pull-up holds it high when floating.
2 VCC power_in Power supply input; place a 0.1 µF decoupling capacitor between VCC and GND, with the device operating from 1.0 V to 5.5 V.
3 GND power_in Ground reference for all signals (0 V).
4 PFI input Power Fail Input, the noninverting input to the power fail comparator; PFO goes low when PFI is below 1.25 V, and PFI should connect to GND if unused.
5 PFO output Power Fail Output from the power fail comparator, which goes low when PFI is less than 1.25 V.
6 WDI input Watchdog Input; if WDI stays either high or low for longer than the 1.6 s watchdog timeout period, WDO goes low, and each transition on WDI resets the timer.
7 RESET output Active-high reset logic output (CBM706P only), the inverse of RESET, held for 200 ms after VCC rises above the reset threshold or MR goes high.
8 WDO output Watchdog Output that goes low when the watchdog timer times out from WDI inactivity or during low line conditions, and remains low while VCC is below the reset threshold.
