IntroductionPMIC (Power Management Integrated Circuit) is a device that combines multiple power-management functions into a single integrated circuit. Supervisors are a type of PMICs that monitor the voltage and current levels of other circuits. The S-80924CNPF-G8UTFG is a supervisor from the S-80 series developed by Siloneo Technology, designed to simplify the implementation of power-management systems. The chip provides monitoring of up to eight power rails and can be used in a range of applications, such as in medical and industrial equipment.Application FieldThe S-80924CNPF-G8UTFG can be used in a range of applications, including industrial, medical and consumer electronics. It is suitable for applications where precision is needed and where there is a need to manage multiple power rails. It can be used to monitor and control various power rails that are integral to the system, such as a general purpose interface (GPIO), a power-on reset generator and a switching regulator.It is also suitable for providing a supervisor function in situations where space and cost are key considerations. It can be used in devices such as tablets, wearable devices and other devices that need to conserve space and reduce costs.Working PrincipleThe S-80924CNPF-G8UTFG provides monitoring of up to eight power rails. It has two general-purpose interfaces, one for monitoring and one for controlling the power rails. The chip offers overcurrent, overvoltage and undervoltage protection, as well as temperature range protection and foldback for better thermal protection.The chip integrates a watchdog timer, which can reset the system to its last known good state if a fault is detected. It also has an active “supply supervisor” with support for up to eight extreme manual reset supply actions, allowing it to remain operational even in cases of extreme environmental conditions.The chip operates in multiple modes, such as fixed voltage mode, adjustable voltage mode and remote voltage monitoring mode. In fixed voltage mode, it can provide a voltage output. In adjustable voltage mode, it can be adjusted to maintain a pre-defined output voltage that is below the supply voltage. In remote voltage monitoring mode, it can monitor the voltage levels of the input system and provide a return signal that tells the system whether to enable or disable the power circuit.The S-80924CNPF-G8UTFG also integrates an onboard digital-to-analog converter, allowing it to be used as a general-purpose DAC in systems where precision is required.The chip is well-suited to a range of applications and can provide a supervisor function with multiple power rails, overvoltage and undervoltage protection, support for extreme temperature ranges, and onboard DAC capabilities.ConclusionThe S-80924CNPF-G8UTFG is a supervisor from the S-80 series developed by Siloneo Technology, designed to simplify the implementation of power-management systems.
