Power Management Integrated Circuits (PMICs) are an important part of the design of any electronic device. They provide the ability to manage and control power to different parts of the device such that it runs efficiently, reliably, and sustainably. Depending on the specific design goals, different types of PMICs can be used, such as controllers, supervisors, regulators, converters, and many others. One of the most commonly used supervisors is the S-80860CLPF-B7LTFU. This article will discuss the application areas and principles of this component.

The S-80860CLPF-B7LTFU is a supervisor chip that provides protection and monitoring of power supplies, battery systems, and voltage rails. This component is most commonly used in automotive applications and portable devices, like cell phones and tablets. The primary benefit of using this component is its low power consumption. It requires only 0.25µA of operating current, allowing for long battery run-time. Additionally, the component functions in a wide voltage range of 1.14 V to 5.5 V.

TheS-80860CLPF-B7LTFU integrates many features that make it ideal for automotive and mobile applications. These features include voltage monitor window detect, watchdog timer, power gate control, low-voltage detector, and sequential power turn-on. The built-in voltage window detect feature allows the component to monitor two separate voltage levels and detect when either the lower or upper level is crossed. This feature can be used to detect faults in the system caused by component failures or power supply issues.

The watchdog timer within the component provides protection against system malfunctions. The timer has a 16-bit programmable width, allowing it to be set to a desired timeout duration. If the system fails to complete its clock cycle during the allocated timeframe then the component will initiate the shutdown of the system.

The power gate control within the component allows the designer to select one of the two supplies in the system, such as the main power supply or the battery power supply. This allows the user to select a specific power source for the device, depending on its requirements. The low-voltage detector feature allows the component to monitor the battery voltage and detect when it is too low and needs to be recharged or replaced.

The sequential power turn-on feature of the component allows the user to control the order in which the supplies in the system are turned on. This prevents noise interference and possible damage to the system caused by abrupt power-up. This feature is particularly useful in automotive applications where multiple power sources are needed to power different components.

In addition to the various protection and monitoring features, the component also provides diagnostic and logging functions. The diagnostic feature allows the user to monitor and detect possible faults in the system while the logging feature allows the user to record various events within the system.

Overall, the S-80860CLPF-B7LTFU is a reliable and efficient supervisor chip with wide operating voltage range, low power consumption and multiple protection features, making it ideal for automotive and portable electronic devices. The component\'s features provide reliable protection against system malfunctions and enable the designer to control the power sources within the device. With its robust features and diagnostic capabilities, the S-80860CLPF-B7LTFU is one of the most popular supervisors used in the market today.
