PMIC - Supervisors

PMIC (Power Management Integrated Circuit) supervisors are integrated circuits (ICs) specifically designed to provide power management functions, such as voltage supervisor, power under-voltage, current sensing, brownout or power-on detection, over-voltage protection and programmable-voltage monitoring.

The S-80815CNPF-B8ATFG, manufactured by Ricoh, is an 8-channel power monitor, voltage supervisor and timer circuit that can monitor multiple system voltages, trip threshold levels and offer micro-sequencing functions all at once. The device is tracking multiple channels of power, voltage, and timer functions in finite load scenarios and is a popular choice of power management in today’s industrial applications.

Application field

The S-80815CNPF-B8ATFG is widely used in industrial applications such as power supply, server, telecommunications equipment, power supply design and digital products. The device is a highly integrated solution that can monitor and generate alarm signals when under- or over-voltage behavior is detected, enabling the device to be an important component for protection and management of system power and voltage in digital systems.

It is also used for monitoring and protecting secondary power for equipment such as battery packs, providing alarm and alert signals in the event of a low-voltage or over-voltage condition. It can be used for the optimal power management of the battery while avoiding large transients in the cell voltage.

Working Principle

The S-80815CNPF-B8ATFG uses a ready-to-use voltage detector IC with two power supplies and two levels of switching voltage monitoring. It can monitor voltage and detect under-voltage or over-voltage conditions, and generates an output signal in response. It is also used for micro-sequencing. Micro-sequencing is a process of employing multiple output signals from a voltage detector device in tandem with a power management integrated circuit to generate an alert in the event of under- or over-voltage system conditions.

The device works by monitoring various system parameters and when it detects an over-voltage or under-voltage condition, it generates an alarm signal. It is then coupled with a power management system, which subsequently regulates the systems’ output energy. The S-80815CNPF-B8ATFG is a cost-effective solution for power management applications in digital systems.

Conclusion

The S-80815CNPF-B8ATFG is a voltage manager and power monitor IC made by Ricoh and its application field is mainly in telecommunications, power supply design and digital products. It works by tracking multiple channels of power, voltage and timer functions in finite load scenarios and generates an output signal if an under- or over-voltage condition is detected. It can also be used for micro-sequencing and is a cost-effective solution for power management applications in digital systems.
