Power management integrated circuits (PMICs) are a component of many electrical devices and systems that require precise voltage regulation, monitoring, power sequencing, and power delivery. Supervisors, a subset of PMICs, are designed to provide a level of safety and protection to the device and its components by monitoring the system’s behavior and responding to any concerns. The S-80821CNUA-B8GT2U is a low current low voltage supervisor from Diodes Inc., and as such strictly adheres to the expectations of a supervisor.

Application Field

The S-80821CNUA-B8GT2U is an ideal supervisor for use in home and industrial appliances, automotive, and recreational vehicles. With its low voltage requirements, the S-80821CNUA-B8GT2U can be used in any system that requires precise power regulation and reliability. This supervisor is designed to provide high performance with low pin count and a maximum monitoring capability of five channels.

The low operating temperature range of the S-80821CNUA-B8GT2U ensures that the supervisor can be deployed in a variety of environments without the risk of trips and false alarms. Furthermore, this supervisor is designed to protect the device and its components against brownout and power sequence violations.

Working Principle

The S-80821CNUA-B8GT2U supervisor is designed around a voltage monitoring controller and five separate low current channels. The voltage monitoring controller monitors supply and reset voltage levels, providing control logic for the supervisor. This logic facilitates proper power-on reset and brownout reset operations, as well as power sequencing and reset generation.

The five channels are powered from the VDD pin and are dedicated to monitoring the system peripherals. Each channel is provided with an active-low reset output terminal, allowing the peripheral to be reset if necessary. Furthermore, the supervisor is equipped with a reset signal, an open-drain output terminal, which can be used to signal an alarm/shutdown state of the system.

In addition to monitoring and reset operations, the S-80821CNUA-B8GT2U supervisor provides a wide range of features such as different adjustable thresholds, programmable delays, and status flags. Each feature serves the purpose of providing safety and protection to the device and its components, while also providing a high level of flexibility and control.

Conclusion

The S-80821CNUA-B8GT2U is an ideal supervisor for use in any system that needs precise power regulation and flexibility. With its low voltage requirements, wide operating temperature range, and monitoring capabilities, the S-80821CNUA-B8GT2U provides a robust and reliable solution for any power management system. Furthermore, the supervisor is equipped with a range of features, such as adjustable thresholds, delays, and status flags, that ensure that the device and its components are provided with a level of safety and protection.
