Introduction

The S-80158CNPF-JLJTFG is a power management integrated circuit supervisor, or PMIC-Supervisor, which is integrated on a single chip. It contains buffered PROGRAMMABLE interruption logic, power-on reset (POR) logic and a watchdog timer that is useful for fault detection. The S-80158CNPF-JLJTFG can monitor power supplies and control reset signals, making it a powerful component for embedded applications and systems.

Application Field

The S-80158CNPF-JLJTFG is designed for use in automotive, industrial and consumer electronics applications. It can be found in microcontrollers, MCUs, safety systems and power converters in these applications. Specifically, this PMIC-Supervisor is used to monitor power supplies, detect faults and reset systems accordingly.

Features

The S-80158CNPF-JLJTFG offers various features that make it suitable for a wide range of applications. Some of its features include:- Power-on reset (POR) so that the IC powers itself up without the need of a manual reset- Programmable reset times- Monitors voltage levels and can trigger reset based on voltage levels- Wide supply voltage range of 2.2V to 15V- Can detect internal and external temperature- Over Temperature (OT) detector to protect against thermal overload- Interrupt Time-Out (ITO) detection to cause reset when a watchdog timer fails

Working Principle

The S-80158CNPF-JLJTFG works by monitoring and comparing input voltage levels. It uses specialized resistors to monitor and compare the voltage levels in the circuit, based on the reference set by the user. When the voltage deviates from the reference, the S-80158CNPF-JLJTFG triggers a reset. It also has a configurable Delay Time Reset (DTR) feature that is used to ensure reset after a specific delay.In addition to monitoring and comparing voltage levels, the S-80158CNPF-JLJTFG also features a watchdog timer that is used to detect ITO events. This is a back-up system that is used to detect situations where the user code is stuck or has crashed. When an ITO event is detected, the S-80158CNPF-JLJTFG triggers a reset, allowing the system to recover.

Conclusion

The S-80158CNPF-JLJTFG is a powerful PMIC-Supervisor that is used to monitor power supplies and detect faults. It offers various features that make it suitable for automotive, industrial and consumer electronics applications, including monitoring of input voltage levels, power-on reset, wide supply voltage range, over temperature detector, and interrupt time-out detection. Furthermore, the S-80158CNPF-JLJTFG works by monitoring and comparing input voltage levels, as well as triggering a reset upon ITO events.
