The X40021V14I-C supervisor is designed to provide reset and supply-voltage monitoring functions in modern high-performance applications. This supervisor allows seamless integration in a variety of systems, including in automotive, industrial, and communication applications. This supervisor is based on a precision voltage comparator and precise voltage monitoring with power-on reset signals. It operates with a single power supply of 3.0V to 32V and is offered in a small, compact SOIC8 package. In addition, it is equipped with high-speed reset circuitry to ensure proper reset timing when supply voltage is varying at slow or fast rate.

The X40021V14I-C is designed to monitor supply voltages above, at, and below a selected trip point. It is powered by a single power supply, and it monitors the input voltage. The X40021V14I is equipped with an adjustable trip point function, and the trip point is adjustable from 1.8V to 4.475V. It has a low power consumption of typically 5mA max and a low operating current of typically 10A max. The X40021V14I-C also offers an open-drain RESET output signal, providing an active-low active-high pulse in case of low supply voltage. The X40021V14I-C can be used in applications with a single power supply from 3.0V to 32V.

In its basi form, the X40021V14I-C supervisor is used for reset and supply-voltage monitoring functions in a variety of applications. Industrial controllers, engine controllers, robots, and power-on systems use the supervisor to monitor the supply voltage and reset the system when the voltage drops below the set trip which prevent data loss and malfunctioning of the system. In the automotive industry, the supervisor is used to reset electronic control units such as engine control units, airbag control, and ABS control when the car encounters an under-voltage situation. Additionally, the supervisor is used in communication and networking applications, such as routers and switches, to ensure power supply stability, maximize system uptime and ensure reliable performance.

The X40021V14I-C supervisor works by monitoring the input voltage. When the input voltage reaches a set trip point, the supervisor triggers a reset signal. The adjustable trip point function allows the user to adjust the trip point from 1.8V to 4.475V. The X40021V14I-C also offers an open-drain RESET output signal, providing an active-low active-high pulse in case of low supply voltage. Additionally, the supervisor has a low power consumption and low operating current, ensuring low standby power and a long lifetime of the system. Therefore, the X40021V14I-C is ideal for applications that require voltage monitoring and reset functions.

In conclusion, the X40021V14I-C supervisor is an ideal and versatile solution for a variety of applications, including in automotive, industrial, and communication applications. The supervisor is small and compact and offers adjustable trip point, low power consumption, and low operating current for reliable performance. It is suitable for applications that require voltage monitoring and reset functions, and it is an efficient, reliable, and cost-effective device for monitoring supply voltages.
