Application Field

The X5168S8-2.7AT1 has a broad range of applications in industrial, automotive, and consumer electronics, computers, and telecommunications. In industrial applications, it is used to protect power systems from over-voltage, under-voltage, and overload conditions, as well as provide power-on reset protection, battery low voltage detection and disconnect/reconnect control, and other types of protection. In automotive systems, it is used to provide various types of protection against power transients and overloads. In computer and telecommunications systems, it provides protection against power surges, overcurrent, and undervoltage conditions to protect the system’s components and the data it stores.

Working Principle

The X5168S8-2.7AT1 is a monolithic integrated circuit and uses a combination of voltage and current sensing techniques to detect and control power system faults and provide protection to the power system. It consists of two input and one output stages with different levels of protection for optimal performance. The input stage consists of a reference voltage regulator and a voltage comparator which compare the input voltage with the reference voltage and generate an active-high status flag. The output stage consists of a response circuit and a MOSFET which control the power FET and monitor the system current to detect overcurrent and undercurrent states.

The reference voltage regulator maintains a constant reference voltage regardless of the input voltage making it suitable for a wide range of applications. The voltage comparator compares the supply voltage and reference voltage and generates an active-high status flag when the supply voltage exceeds or falls below a pre-determined threshold set by the user. The response circuit and the MOSFET then use this status flag to control the power FET and monitor the system current to detect an overcurrent or undercurrent state. If either of these states is detected the MOSFET turns off the power FET and locks it off until the fault is resolved.

The X5168S8-2.7AT1 offers comprehensive protection for power systems in a variety of applications. Its novel design offers improved protection and enhanced power efficiency by constantly monitoring the system’s voltage and current to detect any deviations from the predefined thresholds. Additionally, its wide range of features and its versatile design make it suitable for a wide range of applications. The X5168S8-2.7AT1 is the perfect solution for any power system needing reliable and robust protection.
