PMIC - Supervisors are a type of integrated circuits (ICs). They are used to provide power supply monitoring and control for many electronic devices. S-80154CNPF-JLFTFU is a highly integrated 2‐channel supervisor, which is designed to offer simple, low-cost power monitoring and voltage supervision in distributed power systems. It features a wide operating temperature range, an internal temperature sensor and two dedicated monitoring channels.

The application field of S-80154CNPF-JLFTFU mainly lies in distributed power systems, such as LED lighting and other smart-home systems. This supervisor IC monitors the power supply’s voltage and current levels, as well as the temperature of the device. It also provides accurate over‐voltage and under‐voltage monitoring, as well as over‐temperature monitoring.

The S-80154CNPF-JLFTFU has two monitoring channels that are independently configurable and share a common manual reset input. The supervisor detects rising and falling voltage levels, as well as over‐voltage and under‐voltage events. It also has an internal temperature sensor that can be configured to detect over‐temperature conditions. Additionally, the IC has a power‐on reset to ensure correct system initialization.

The S-80154CNPF-JLFTFU also features an active pull-up or pull-down resistor on the external reset output pin, which allows the device to have an adjustable de-bounce time. The supervisor allows the user to define the time that the device needs to be in a valid state before it will consider the system reset as valid. This feature is useful as it prevents multiple reset signals being generated due to false positives.

The working principle of S-80154CNPF-JLFTFU is simple yet effective. It monitors the voltage, current and temperature of the device and detects any irregularities that can cause system instability or failure. The supervisor has a manual reset input and two dedicated monitoring channels that can be configured independently. When the supervisor detects an abnormality, it will generate an interrupt signal or reset signal and the system will react accordingly.

In summary, the S-80154CNPF-JLFTFU is a highly integrated 2‐channel supervisor designed for distributed power systems. It is a great choice for projects such as LED lighting and other smart-home systems that require reliable power monitoring and voltage supervision. It provides accurate over‐voltage and under‐voltage monitoring, as well as over‐temperature monitoring. The manual reset input and the dedicated monitoring channels allow the device to be configured independently, while the active pull-up or pull-down resistor enables an adjustable de-bounce time. Overall, the S-80154CNPF-JLFTFU is an ideal choice for robust and reliable power monitoring application.
