S-80833CNUA-B8ST2G Working Principle

The S-80833CNUA-B8ST2G PMIC - Supervisor is composed of a power supply circuit, a voltage detection circuit, an output voltage voltage regulation circuit, a temperature determination circuit, and other control circuits. The power supply circuit contains several voltage dividers. When the supply voltage output to the system is higher than a preset value, the output voltage voltage regulation circuit will detect it and reduce the output voltage. When the supply voltage is lower than the preset value, the output voltage will be increased. The current output can also be adjusted via the power supply circuit.

The voltage detection circuit is used to detect the voltage of the system. It contains N-Channel MOSFETs which can detect the supply voltage level and send the information to the temperature determination circuit. The temperature determination circuit can detect the temperature of the system and control the output voltage accordingly. The output voltage voltage regulation circuit prevents system from overvoltage and undervoltage conditions. This circuit contains an N-Channel MOSFETs which can serve as an active element to adjust the output voltage through controlling an output transistor.

The S-80833CNUA-B8ST2G also contains an open drain output circuit which can output a reset signal to the system when it detects a voltage fault condition. This reset signal can reset the system and protect it from overvoltage, undervoltage and other abnormal conditions.

Conclusion

The S-80833CNUA-B8ST2G PMIC - Supervisor provides protection for various types of embedded systems by monitoring and controlling voltage levels. With features such as voltage detection, temperature determination, and protection against overvoltage and undervoltage, it is a vital component for embedded systems which need reliable protection from abnormal voltage conditions. It is an important part of the PMIC family and can be used in various application fields.
