PMICs (Power Management ICs) are an integral part of any circuit design, whether it is a industrial or consumer application. The X40035V14I-C is a highly integrated single-supply supervisor with low power consumption, high accuracy, and comprehensive monitoring capability. It is an ideal solution for applications requiring control and safety of a microcontroller-based system.

Applications

The X40035V14I-C is suitable for a wide range of applications, such as microcontrollers, motor control, automotive, liquid crystal displays (LCDs), hardware security, etc. It can be used to protect a system from power faults and reset a microcontroller after power loss. It is also suitable for use in portable applications and low-power applications.

Features

The X40035V14I-C features an Enhanced Power On Reset (EPOR) with delayed power on-time, active supply voltage supervision, reset input, manual reset control and Power Good output. It has a maximum system supply voltage of 5.5V and a power-on delay time of up to 16ms. The active supply voltage supervision includes selectable voltage thresholds and hysteresis. The EPOR also has selectable delay times. The X40035V14I-C also provides reset input, manual reset control, and Power Good outputs (red and green). The Power Good output can be used to indicate to the user when the system is operating properly.

Working Principle

The X40035V14I-C includes a built-in reset circuit. When the system supply voltage exceeds the threshold voltage, the reset circuit is held in reset. During operation, the EPOR monitors the system supply voltage and when it drops below the reset threshold, the reset circuit is triggered. This resets the microcontroller and prevents the system from running code that may be corrupted. The manual reset feature allows the reset circuit to be forced into reset. The Power Good output indicates to the user that the system is operating properly.

Conclusion

The X40035V14I-C is a powerful and versatile single-supply supervisor with a wide range of features for a variety of application. It is suitable for use in microcontroller and motor control applications, LCDs, automotive, and various low-power applications. It can protect a system from power faults and reset a microcontroller after power loss. It also provides selectable voltage thresholds and hysteresis, reset input, manual reset control, and Power Good outputs.
