X40421V14-B, an integrated circuit that offers circuit protection, supervisor, and real-time clock (RTC) functions, is part of the PMIC - Supervisors family. It is typically available as an 8-pin Volatile Memory (VM) chip.
X40421V14-B Application Field:
This IC is specially designed for embedded system applications. It can be used in embedded systems of all kinds, like communications, consumer electronics, industrial control and other applications where low power consumption and high reliability is required.

The X40421V14-B offers a wide range of features and protection circuits that simplify system design and provide high protection against voltage and temperature transients. It features an 8-bit data width, auto-shutdown at during power-on reset, an integrated watchdog timer, a programmable power-on reset sequence, and an external reset generator with a wide input voltage range. This IC also offers a low power consumption with an initial start-up from 2μA. It provides a variety of protections including input voltage, output voltage, output current, under-voltage lockout (UVLO) and overtemperature protection.

X40421V14-B Working Principle:
The X40421V14-B IC includes a built-in system supervisor for monitoring power supplies voltage, temperature and operating conditions. An advanced RX reset logic monitors all power supply conditions and generates a reset signal if needed. It utilizes a low-power RTC oscillator to address the need for better system reliability and long battery life in mobile-based applications. The built-in watchdog timer circuit provides an independent protection of the embedded system while helping to reduce system power requirements. The chip also provides a high level of protection against input-voltage transients with a powerful ESD protection circuit.

The X40421V14-B integrated circuit is ideal for embedded system applications that require high protection, low power consumption, and reliable operation. It offers superior protection against input-voltage transients and over-temperature conditions, and provides a programmable power-on reset sequence. This IC is well suited for the emerging markets requiring voltage supervisor and RTC functions in a single chip.
