Power Management Integrated Circuit (PMIC) Supervisors are a critical part of any modern electrical system that must remain stable, safe and reliable. An integrated circuit (IC) supervisor is a specialized integrated circuit that constantly monitors the power and voltage level of the system. The S-80822CNPF-B8HTFU is one such IC supervisor that is designed to provide overvoltage protection and reset control for moderate to high power applications.

The S-80822CNPF-B8HTFU monitors the input/output voltages and applies overvoltage protection. The device has an adjustable overvoltage threshold level of 3.2V to 5.5V. The integrated voltage supervisor continuously monitors the input voltage to ensure it remains above or below the set threshold level. If the threshold is exceeded, the device will initiate a reset action. The reset action can be in the form of a reset pulse or assertion of an interrupt signal. The S-80822CNPF-B8HTFU also has a UVLO (Under Voltage Lockout) function which disables the device when the input voltage falls below a certain threshold. This prevents overdischarging of Lithium-ion batteries.

The S-80822CNPF-B8HTFU provides very accurate overvoltage protection, due to its internal precision voltage references. It also has a power-on reset (POR) feature, which enables the circuit to automatically reset itself upon the application of power. This ensures that the system starts functioning correctly after an extended power outage. The device supports dual reset pin independently configurable as active-low or active-high outputs, allowing flexibility of system design.

The S-80822CNPF-B8HTFU’s layout and design gives system designers the ability to integrate it into small form factor applications. Its use of surface mount technology makes it easy to incorporate into modern systems. The S-80822CNPF-B8HTFU can be connected directly to the power supply or output terminals of the monitored components. This simplifies the wiring complexity and space requirements of the design.

The device exhibits excellent temperature performance and reliability. Its tight voltage monitoring threshold accuracy and extremely low quiescent current enable it to monitor battery discharge, enabling it to be used in applications such as energy harvesting and portable computing. The device also offers fast response time, high surge voltage tolerance and an integrated power-up sequence.

The S-80822CNPF-B8HTFU is an excellent choice for circuit designers seeking an effective overvoltage protection solution for moderate to high power applications. With its compact dimensions, low power consumption and reliable performance, it can help circuit designers design a power-efficient and robust system.
