S-80921CLPF-G6RTFG

PMIC, an abbreviation for Power Management Integrated Circuit, is the central component of an electronic device that is responsible for distributing power throughout the device. One type of PMIC is a Supervisory Circuit, which is used to regulate system voltage and current levels, as well as monitoring for a variety of system faults. The S-80921CLPF-G6RTFG is a Supervisory Circuit IC from Renesas Electronics that is designed to provide high accuracy, low power consumption, and fast response times in a wide range of applications. This article will discuss the application field and working principle of the S-80921CLPF-G6RTFG.

Application field

The S-80921CLPF-G6RTFG is a compact, low power consumption, low-emission Supervisory Circuit that is designed with a wide range of applications in mind. It is ideal for automotive ECUs, electric motor control, high-precision electrical control systems, industrial electric measurement and control systems, power conversion systems, power line communication systems, and home appliance systems. In automotive systems, it can be used to maintain power even if the battery voltage is too low, reducing the risk of complete system failure. In electric motor control, it can be used to monitor for overcurrent conditions and shut off power to protect the motor. In industrial systems, it can be used to monitor for overvoltage or undervoltage conditions and prevent harm to components.

Working Principle

The S-80921CLPF-G6RTFG is designed around a switched capacitor voltage monitor. This type of device works by monitoring the input voltage and comparing it to an internal reference voltage. When the voltage rises above or drops below the reference voltage, an internal comparator triggers and signals a voltage-output terminal. This activates various system protection functions such as a power-down circuit or warning circuit. In addition, the S-80921CLPF-G6RTFG also includes a delay circuit, which is used to maintain power even when the input voltage fluctuates slightly due to load variations.

The S-80921CLPF-G6RTFG is a reliable and efficient Supervisory Circuit that is ideal for a wide range of applications. Its low power consumption and fast response times make it an excellent choice for automotive ECUs and industrial electric measurement and control systems. Its wide operating voltage range and internal delay circuit allow it to monitor for overcurrents, undervoltages, or other system faults, protecting critical components and preventing catastrophic system failure.
