S-80157CNPF-JLITFG

Introduction

S-80157CNPF-JLITFG is an integrated circuit chip from STMicroelectronics. It is a power management integrated circuit (PMIC) that functions as a supervisor for system power. It monitors and maintains the integrity of the power circuits in a system, providing quick and reliable protection against power voltage failure and abnormally high current. It is a one-chip, low-pin count device that can replace multiple supervisor ICs and reduce the cost and complexity of the system board.

Application Field and Working Principle

The S-80157CNPF-JLITFG supervisor is most commonly used in personal computers, major appliances, and data processing applications. Its main functions include power-on reset (POR), power failure warning (PFW), low battery reset (LBR), power distribution monitoring (PDM), and temperature monitoring and protection.

The S-80157CNPF-JLITFG supervisor incorporates several digital and analog functions dedicated to managing power in system applications. It can detect low power from a battery or wall input. It includes a comparator that can detect any power failure above a certain voltage threshold. This voltage threshold can be adjusted using external resistors.

The device also includes a digital-to-analog converter for temperature monitoring and protection. This can be used to detect a range of critical temperature events, such as overheating, cold temperatures, and open-circuit conditions.

The device also incorporates several low-level analog and digital functions to detect power overloads and shorts, in addition to providing quick, reliable protection against overvoltage and reverse-polarity conditions.

Conclusion

The S-80157CNPF-JLITFG supervisor from STMicroelectronics is a power management integrated circuit (PMIC) that can provide reliable protection against power voltage failure and abnormally high current. It includes a range of digital and analog functions dedicated to managing power and detecting power overloads and shorts. It is ideal for use in personal computers, major appliances, and data processing applications.
