Introduction

The X4283S8I-2.7 is a power monitoring IC (PMIC) commonly used in electronic devices. It is part of the popular X4 series of PMICs developed by a leading semiconductor manufacturer, and is classified as a supervisor, meaning it is used to monitor power supplies and provide protection against short circuits and overloads.

Application Field

The X4283S8I-2.7 is typically used in portable and computing devices where power saving is a major consideration. It is designed to quickly detect outages or other fluctuations in the power supply, allowing for the prompt activation of countermeasures and the resumption of normal operation. It is most commonly used in laptop computers, tablets and smartphones.

Features

The X4283S8I-2.7 is designed to provide maximum power efficiency in a compact package. It features current measurement accuracy of ± 2 μA and voltage measurement accuracy of ± 150 mV. It is also capable of operating within a wide temperature range, from -20°C to + OS°C. With an operating current of only 450 μA and a standby current of only 0.5 μA, the X4283S8I-2.7 provides outstanding power efficiency.

Working Principle

The X4283S8I-2.7 is composed of two main components: a power monitor and a power switch. The power monitor continuously monitors the power supply voltage, current, temperature and other parameters and sends signals to the power switch when any of these parameters falls outside the predefined range. The power switch then interrupts power supply and shuts down the device, preventing damage due to overload or faulty power supply.

Conclusion

The X4283S8I-2.7 is an advanced PMIC designed for reliable and efficient power management in portable devices. It is a simple and robust device, offering excellent protection against power outages and fluctuations. With features such as high current and voltage accuracy, low operating current and wide temperature range, the X4283S8I-2.7 is an ideal solution for portable and computing devices.
