 CBM811/CBM812 Product Applications

The primary function of the CBM811/CBM812 is to precisely monitor the input voltage and execute corresponding control logic outputs strictly according to designed timing sequences, thereby flexibly accommodating diverse system application design requirements. In addition to monitoring multiple voltages, the CBM811/CBM812 series features an input debounce function, MR, which ensures a reliable manual reset. These devices generate dependable reset signals under scenarios such as power-on, voltage dips, or voltage fluctuations, thereby safeguarding the overall reliability of system operation. The following is a functional block diagram of the monitoring circuit:

 CBM811/CBM812 Product Highlights

Corebai Electronics' CBM811/CBM812 are highly reliable precision voltage monitoring devices, suitable for the vast majority of voltage monitoring applications. Different models cater to the monitoring of different voltages and the provision of distinct reset outputs.

The manual reset feature of the CBM811/CBM812 proves particularly valuable when the circuit in which they are employed enters a state discernible only by the user. Allowing users to manually reset the system mitigates potential damage or hazards that may arise from system runaway or lockup. The manual reset input is equipped with a debounce circuit, ensuring the reliability of manual operations.
