PMIC - Supervisors

The S-80859CLNB-B7KT2G is a type of PMIC supervisors. It is typically used to reset peripherals, including MCUs and ASICs, when they go into an unpredictable state. It performs supervisory tasks such as controlling reset, power failure warning, and alarm signaling.

Application Field

As a PMIC supervisor, the S-80859CLNB-B7KT2G is useful in a variety of applications, including:

• Portable Electronics: The reset feature helps to ensure reliable operation of mobile devices.
• Consumer Electronics: The reset feature helps ensure that consumer electronics are always in working order.
• Industrial Automation: The reset feature enables the autonomic automation of processes, making operations more efficient and cost-effective.
• Embedded Systems: The reset feature ensures the stable functioning of embedded systems.

Working Principle

The S-80859CLNB-B7KT2G is an active-low reset controller, which means it is activated when the voltage drops below a threshold level. This means that when a peripheral begins to malfunction, the supervisor immediately detects the problem, signals an alarm and resets the device, preventing any further damage.

The S-80859CLNB-B7KT2G has two basic modes of operation. In the normal operation mode, the supervisor monitors the power supply voltage and the operating frequency, ensuring that the peripheral operates within its specified parameters. In the power-down mode, the supervisor monitors whether the power supply voltage has dropped below a certain level, indicating a power failure. In this mode, the supervisor signals an alarm and resets the peripheral.

Conclusion

The S-80859CLNB-B7KT2G belongs to the PMIC family and is used as a supervisor. The supervisor monitors the power supply and operating frequency of peripherals, and signals an alarm and resets the device when the power supply drops below a certain threshold level, preventing further damage. The S-80859CLNB-B7KT2G is used in a variety of applications, including portable electronics, consumer electronics, embedded systems, and industrial automation.
