The S-80816CNPF-B8BTFU is a family of PMIC – Supervisors which is the integrated circuit (IC) used to monitor voltages in the power supply lines, rapidly responding to the output voltage of the regulator to ensure it is within its tolerance levels, as well as enabling system resetting during certain scenarios.

The S-80816CNPF-B8BTFU is designed for highly space-constrained systems. Featuring a low external component count, it is optimised for application requiring a very small solution size, with many external components already incorporated into the IC. In addition, it contains a dedicated low voltage detect circuitry that enables system resetting during low voltage situations.

Application Field

The S-80816CNPF-B8BTFU is typically used in low voltage power supplies, such as DC/DC converters, linear regulators, and switching regulators, where it efficiently monitors voltage output, providing system resetting when needed.

Working Principle

The S-80816CNPF-B8BTFU uses an internal bandgap reference to accurately measure the output voltage of the regulator connected in-circuit. It then compares that measured voltage to a user-defined target voltage, with the result being used to adjust the trigger threshold of the system resetting. Whenever the measured voltage of the regulator goes outside of its predefined tolerance levels, the S-80816CNPF-B8BTFU will immediately signal a reset, thereby preventing the system from damaging components within it.

The S-80816CNPF-B8BTFU features a wide operating temperature range (from -40°C to 125°C). It is also capable of surviving voltage surges up to 25V in absolute maximum ratings, enabling it to function in environments where power fluctuations can occur, such as in automotive and industrial applications.

The S-80816CNPF-B8BTFU is highly configurable, allowing it to be easily tailored to fit the application’s needs. It also houses various adjustments, such as the trip point, hysteresis, and filter setting, thereby ensuring it can detect any output voltage quickly and accurately.

With its high accuracy monitoring and quick responding capabilities, the S-80816CNPF-B8BTFU is a powerful, cost-effective monitor, ideal for any application requiring tight voltage regulation.
