The X40031S14-C is a PMIC – Supervisors from Xicor. It is a cost-effective and reliable supervisor IC used for monitoring critical voltage supply rails, providing reset signals, along with short circuit and brown-out protection. This IC helps protect sensitive ICs from supply rail brown-out and over-voltage conditions.

The X40031S14-C offers low-voltage protection of microprocessors and peripheral ICs, without the need for additional discrete components. This IC provides comprehensive power supply management functions: reset output generation (including reset timeout capabilities); reset sequencing between several devices; cycle-by-cycle over-current protection; and under-voltage protection (UVLO).

Key features of the X40031S14-C include: an active-high reset output with a low-current (5 μA) driving capability; adjustable reset timeout, up to 1 second; active-high overtemperature warning output; active-high undervoltage reset output; current-limit with cycle-by-cycle current-sensing feature; and 1% over-voltage and 2% under-voltage trip accuracy.

The X40031S14-C can be used in a variety of different applications, such as automotive systems, industrial controls, and embedded systems. It is particularly suitable for applications where the protection of sensitive ICs from supply rail brown-out and over-voltage is critical. The over-voltage and under-voltage trip points of the IC can be easily programmed by means of external resistors. The reset signal can also be programmed to stay active for a certain period of time before returning to the low state.

The X40031S14-C can be used in applications where precise control is essential and where reset timeout capabilities is required. The IC works by constantly monitoring the input voltage and generating a signal when the voltage drops below the pre-determined limit. When the voltage rises back above the limit, a reset signal is generated. The IC also features a timeout function which can be programmed to keep the reset signal at the active level for a pre-determined amount of time. In the event of an over-voltage or under-voltage condition, the IC will keep the reset signal active for an extended period of time, thus protecting the connected ICs from possible damage.

In conclusion, the X40031S14-C is an ideal solution for applications where reliable and precise monitoring of the supply voltage is important. It provides an efficient and cost-effective way to protect connected ICs from over-voltage and under-voltage conditions. With its adjustable reset timeout and current-sensing feature, the X40031S14-C is a reliable solution for various applications in the automotive, industrial, and embedded systems markets.
