Power Management Integrated Circuits (PMICs), also known as supervisors, are electronic devices used for controlling electrical power, which can improve the efficiency of power management compared to a single power switch. The S-80857CLNB-B7IT2G supervisor is a highly integrated power management device designed to provide efficient and reliable power management solutions to end users. This supervisor offers a wide range of features such as integrated overvoltage protection (OVP) and overcurrent protection (OCP), along with power sequencing, voltage monitoring and diagnostics capability.

The S-80857CLNB-B7IT2G supervisor is designed to offer the highest level of integration by integrating the supervisor die with additional components such as N-channel MOSFETs, resistor dividers, current sense amplifiers, and even additional circuitry to provide an ultra-small solution that is highly reliable and requires minimal external components. The integrated solution is designed to protect systems from voltage excursions and over-current limitations, while offering voltage monitoring capabilities and diagnostics reporting at the same time.

The S-80857CLNB-B7IT2G’s primary application field is in portable and fixed application space. This supervisor is widely used in embedded systems and serves as a primary control for system power management. It utilizes a sophisticated power sequencing algorithm that regulates the flow of current when enabled, ensuring safety for all components involved in the system. It is designed to work with both Li-ion and Li-polymer batteries, and is fully compatible with both 1-wire and 2-wire communication protocols.

The S-80857CLNB-B7IT2G supervisor can offer a wide range of operational options such as powering up the load sequentially and automatically, as well as protecting the system from overvoltage conditions. Additionally, the supervisor can monitor various voltage levels and provide a feedback to the controller to improve overall system performance. Moreover, the supervisor is capable of detecting and reporting various errors such as undervoltage and overvoltage conditions, overcurrent protection and thermal protection.

The working principle of the S-80857CLNB-B7IT2G power supervisor is based on a control loop that is used to monitor multiple external parameters. The supervisor continuously samples external voltages, currents, and temperatures. Based on these values, a control logic is used to regulate the system in order to maintain safe operating conditions. The supervisor also utilizes an internal current sense amplifier and an internal temperature sensor, which can be calibrated and configured manually.

The supervisor is designed to operate with a maximum efficiency of 95%, while providing over-voltage protection (OVP) and over-current protection (OCP) to the system. In case of overvoltage or overcurrent conditions, the supervisor will shut down the circuits or switch off the output. This mechanism helps protect the system from anomalies and power interruptions, ensuring reliable and safe operation of the system. Additionally, the supervisor can be utilized for power sequencing, allowing for low-cost power sequencing solutions without the need for additional power sequencing components.

In conclusion, the S-80857CLNB-B7IT2G supervisor is a highly integrated power management device which provides efficient and reliable power management solutions to end users. It utilizes a sophisticated control loop to monitor various external parameters, such as voltages, currents, and temperatures, in order to maintain safe operating conditions. Additionally, it provides over-voltage protection (OVP), over-current protection (OCP), power sequencing and voltage monitoring capabilities, making it an ideal choice for embedded systems that are prone to power disruptions.
