The X40020V14-A is a simple-to-use PMIC (Power Management IC) commercial off-the-shelf (COTS) device, providing supply voltage supervisors and over-current protection (OCP) capabilities. It provides a measure of protection against system damage due to transient overvoltage and over-current conditions.

The X40020V14-A is ideal for applications requiring robust protection of basic components and power sources and limited power management control, such as with portable devices, USB-powered devices, and embedded systems. It offers many advantages over traditional protection circuits and can be more cost-efficient and space-saving than discrete components. It can also reduce the complexity and effort required to design a system while offering higher performance and reliability.

The X40020V14-A is designed to be low-cost, low-power-consumption, and highly reliable, and offers features such as spike and transient protection, active clamping, over-voltage and under-voltage lockout, and over-current protection. It also features a temperature-dependent supply voltage indicator (SVI) for accurate monitoring of temperature inside the system, and a precision reset timer for accurate reset of the system when the regulated supply voltage reached its limit.

The voltage supervisor part of the X40020V14-A operates as a threshold-detector, monitoring supply voltage and generating a reset/signal flag when the monitored supply voltage goes below a preset low threshold. This flag can be used to initiate a reset signal to the system, preventing it from operating in a potentially unreliable state.

The over-current protection function of the X40020V14-A detects high current in a power source using a precision on-chip fuse. When a pre-defined overload current is sensed, the X40020V14-A will de-energize the incoming power source, preventing system reset and eliminating the need for costly reliable power fuses.

The X40020V14-A is designed to be versatile and can be used in a variety of applications such as embedded systems and USB-powered devices. The device is also designed to be easy to use, and requires minimal setup to start protecting your system.

In summary, the X40020V14-A PMIC supervisor provides a cost-effective and reliable solution for providing protection against transient overvoltage and over-current conditions. It features a wide range of features for use in a variety of applications, and it is easy to setup and use. Offering higher performance and reliability than traditional protection circuits, the X40020V14-A is a great choice for applications requiring robust protection of basic components and power sources.
