X5168S8Z-4.5A PMIC - SupervisorsPower Management Integrated Circuits (PMICs) are devices that are used to manage the power supply in portable electronic devices. They are typically integrated into a single chip and have a number of functional blocks for controlling the power. PMICs combine several components that are usually found in discrete solutions, such as voltage regulators, power switches, and power converters. Supervisors are a type of PMIC that are designed to oversee power delivery and ensure that the device is operating safely and reliably.The X5168S8Z-4.5A is a supervisor product from STMicroelectronic that has been designed for protection against sudden over-current conditions in a variety of applications. It features two independent, ultra-low power 45V general-purpose input/output drive stages as well as two independent Supervision Operating Voltage (SOV) trip points with adjustable sensitivity levels. It also offers an analog input signal conditioning stage with integration and signal filtering modes, as well as a digital interface that can be used to set up and control the device.The X5168S8Z-4.5A application field is primarily in portable electronic applications, and it is particularly useful for systems where the output current varies, and/or sudden short-term current surges have to be accounted for. It can also be used in a variety of other applications, such as automotive, industrial, and medical devices, where a sudden over-current condition needs to be monitored and prevented from occurring.The working principle of the X5168S8Z-4.5A is based on its two independent SOV trip points. When the input current crosses the pre-defined trip point, the SOV detects the condition and triggers the logic output which can then be used to shut down the power supply, or take any other appropriate action to protect the system. The SOV also provides an analog output which can be used to better understand the current conditions of the system, and to optimize the system performance.The X5168S8Z-4.5A also features an adjustable hysteresis and a low reset switch, both of which prevent false triggering due to glitches in the current signal. The SOV also protects the inputs from over-voltage levels, and it can withstand up to 85V of static voltage. The device is available in a tiny 3mm x 3mm DFN package, making it suitable for space-constrained applications.In summary, the X5168S8Z-4.5A is a PMIC - Supervisors product from STMicroelectronic that is designed to monitor and control the current in portable electronic devices. It features two independent, ultra-low power general-purpose input/output drive stages and two independent Supervision Operating Voltage (SOV) trip points, as well as an analog input signal conditioning stage and a digital interface for setting up and controlling the device. This device is suitable for use in battery powered applications, automotive, industrial, and medical devices, and can provide protection against sudden over-current conditions.
