S-80147CLPF-JI8TFG

Power management integrated circuits (PMICs) are a type of integrated circuit that are designed for use in computing, telecommunications and other industries where energy management is important. Supervisors are one type of PMICs, designed to provide protection to system microcontrollers and other components by detecting abnormal power conditions and either shutting down the system or taking action to maintain safe operation. The S-80147CLPF-JI8TFG is a type of supervisor, and this article will describe its application field and working principle.

Application Field

The S-80147CLPF-JI8TFG supervisor is typically used in embedded and portable applications. It is especially useful for applications in harsh temperature environments that require precise power regulation. These applications include industrial automation and control systems, consumer electronics, automotive, medical and communications systems.

Operating Voltage

The S-80147CLPF-JI8TFG supervisor operates on a single 3.3V supply. The power-on reset (POR) threshold is adjustable from 1.3V to 5V. A low quiescent current of 1.7uA allows for improved battery life and reliable operation in a variety of applications.

Features

The S-80147CLPF-JI8TFG supervisor features a variety of protection features, including an under-voltage lockout (UVLO), brown-out reset (BOR) with adjustable thresholds, and an adjustable power-on reset (POR) window. It also includes a watchdog timer with adjustable time-out, active-low push-pull reset output, and a programmable reset de-bounce. The supervisor is also capable of monitoring voltage drops and power-supply transients, and can take action to protect the system from damage.

Working Principle

The S-80147CLPF-JI8TFG supervisor monitors the system’s power supply and detects abnormal conditions such as too low or too high voltages, and then takes action to protect the system. This can range from triggering a reset signal to disabling the system, depending on the application.

When the system is shut down, the supervisor monitors the power supply and detects a transition from low to high, where the transition is detected by the device’s voltage detector circuit.

When the device detects a power transition, it will enable the power-on reset (POR) function and then generate a reset signal on its reset output. This signal can then be used to reset the system and restore normal operation.

The watchdog timer can be set to generate a reset signal for any length of time. This can be used to reset the system if the system stops responding. It can also be used to detect intermittent faults and determine if a system has entered an undesired state and then take corrective action.

The S-80147CLPF-JI8TFG supervisor provides a flexible, efficient and robust solution for protecting system microcontrollers and other components from power issues in embedded and portable applications. The integration of multiple protection functions in a single device makes it a cost-effective solution for automotive, medical and communications systems.
