PMIC - Supervisors

A Power Management Integrated Circuit (PMIC) is an integrated circuit that combines various analog and digital functional blocks, including a voltage regulator, an oscillator, a reset circuit, and a battery charger, into a single package. PMICs are essential for a wide variety of electronics and typically serve applications such as battery management, system power management, and motor control. Supervisors are one of the main types of PMICs, and their purpose is to monitor the power and signal conditions of a system and take corrective actions in case of an unexpected event. One of the most popular and advanced supervisors is the S-80813CLPF-B7RTFU, which is specifically designed for fast, cost-effective, and reliable system supervision and control with multiple monitoring functions.

Application Field

The S-80813CLPF-B7RTFU is an integrated supervisor that can be used in a wide range of industries and applications, including the automotive, industrial, telecom, and consumer electronics markets. It is specifically designed to provide a system-level monitoring solution in power-sensitive electronic designs. It features a single-channel watchdog, five interrupt pins, a voltage monitor, three programmable reset outputs, battery-backup support, low quiescent current, and a rich selection of peripheral protection functions. It is well-suited for use in PCs, mobile phones, notebooks, medical equipment, home appliances, and smart wearables.

Working Principle

The S-80813CLPF-B7RTFU supervisor works on a “push-pull” principle where it monitors the input voltage and the operating conditions of a power-sensitive system and then issues a reset signal when the monitoring conditions are not met. The supervisor has an input voltage monitor that detects if an input voltage is below, above, or within a programmable range and transmits a reset signal when it is violated. It also has a watchdog timer, which is a time-interrupt signal that is generated periodically to verify that a system is functioning properly. If the timer is not reset within a programmable time period, it will issue a reset signal. Additionally, the supervisor also has three programmable reset outputs, which can be used to generate reset signals when a certain event or threshold is detected.

Conclusion

The S-80813CLPF-B7RTFU supervisor is a highly-integrated device designed for fast, cost-effective, and reliable system supervision and control. It provides multiple monitoring functions, including an input voltage monitor, a watchdog timer, and three programmable reset outputs, and is suitable for a wide range of applications in the automotive, industrial, telecom, and consumer electronics markets.
