X40434S14I-B

X40434S14I-B is a power management integrated circuit (PMIC) - Supervisors. This type of PMIC is designed to provide a system supervisor solution that offers power-on-reset (POR), supply voltage sequencing and sequencing, low battery voltage monitoring, and temperature monitoring functions. It is an excellent choice for industrial and embedded applications.

Description

The device consists of 4 main blocks: the core reset control, supply voltage monitors, a power-on-reset control, and a temperature monitor. The core reset control block is the main part and is responsible for the reset of the system. This block provides a POR feature with an adjustable delay and pulse width, as well as a more traditional reset behavior. It also provides an active-low power reset enable signal, which allows the system to be reset in response to an external signal. Additionally, it includes a digital output for individual channels that can be used for pin forecast.

Supply Voltage Monitors

The supply voltage monitors provide an advanced power-good output to detect proper system power up. The voltage monitors can be configured to provide either single, dual, or triple voltage monitoring. The circuit can be configured to monitor voltages from 0.5V up to 6V. This flexibility allows the user to create power-up sequencing to ensure proper startup of the system.

Low-battery Voltage Monitor

The low-battery voltage monitor provides a method to detect when a system’s batteries are becoming low. The voltage monitor includes an adjustable threshold for the low-battery input that can be configured to detect when the system is approaching low battery conditions. This can be used to alert the system to take corrective action, such as power down and/or provide voltage regulation.

Temperature Monitor

The temperature monitor provides a flexible way to monitor the temperature of the system. It features 4 user-programmable temperature levels that can be set to detect various levels of thermal conditions. When the internal temperature reaches either of the user-defined levels, the device will provide an active-low temperature-critical notification output.

Working Principle

The main components of the X40434S14I-B are designed to work together to provide a complete supervisor solution. When the supply voltages and/or temperatures reach a set threshold, the device triggers an active-low reset output, thus resetting the system. The POR feature allows the system to be taken out of reset in response to an external pulse, thus ensuring a clean power-up sequence. Additionally, the low-battery voltage monitor can be used to alert the system when the batteries are becoming low, and the temperature monitor can be used to detect thermal abnormalities.

Application Fields

The X40434S14I-B is an ideal solution for industrial and embedded system applications that require robust system reset and supervisor capability. It provides a flexible solution that allows various voltage and temperature monitoring levels, power-good output, etc. The device can also be used in applications where it is necessary to detect low battery conditions or thermal abnormalities in order to take corrective actions. The device\'s small size and low power consumption make it suitable for portable and other space-constrained applications.

Conclusion

The X40434S14I-B integrated circuit is an excellent choice for industrial and embedded systems that require robust power management and supervision capabilities. It offers supply voltage sequencing, low battery voltage monitoring, temperature monitoring, and POR with adjustable delay and pulse width. The device is also small in size and low power consumption, making it suitable for space-constrained applications.
