A PMIC - Supervisors device typically refers to a single power source product family designed to protect a system from damage due to power supply and system related failure. The X4163S8I-2.7 supervisors is a specific device from this family, which is commonly used for voltage monitoring and system reset in embedded systems such as sensor devices, edge computing and digital video. In this article, we will discuss the application fields and working principle of the X4163S8I-2.7.

Application Fields for the X4163S8I-2.7

The X4163S8I-2.7 is able to operate over a wide voltage range, making it suitable for use in a wide range of applications. It is ideal for applications that require power source protection, as well as ultra-low instantaneous current. This can include applications such as IoT-enabled or edge computing devices, process control equipment, automotive systems, or medical imaging technology.

The X4163S8I-2.7 has been designed to meet and exceed the requirements for safety and reliability in highly demanding applications. This device can monitor the voltage of up to two power inputs, and then generate a reset signal if a certain threshold is exceeded. Additionally, it can provide fail-safe protection against transient overvoltage, eliminating the need for costly fusing and overvoltage relay circuits.

Working Principle of the X4163S8I-2.7

The X4163S8I-2.7 is equipped with an integrated high-precision voltage detector circuit, which is able to detect voltages as low as 0.2V above the supply voltage, up to 7V above the supply voltage. It can detect voltage levels up to 6V if the supply voltage is below 6.5V.

This detector circuit is used to monitor two different power supplies, and then generate a reset signal if the voltage at either supply drops below the precise detection threshold. This reset signal is then used to inform other internal circuits in the system of the low-voltage condition, and can also trigger a system reset in order to help reduce the risk of damage.

In addition to reset signal generation, the X4163S8I-2.7 also includes other features such as active discharge and input protection. The active discharge feature allows the device to discharge any residual current before the reset signal is sent to downstream circuits, eliminating the risk of voltage spikes. With the input protection feature, the device is able to absorb up to 33mA of transient current without fail, ensuring that there is no permanent damage to the circuit.

Conclusion

The X4163S8I-2.7 supervisors is a device designed to provide protection and monitoring capabilities for embedded systems and other devices. Its wide operating voltage range, high-precision voltage detection, active discharge, and input protection features make it suitable for use in a broad range of applications. In this article, we discussed the application field and working principle of the X4163S8I-2.7.
