The X40021S14IZ-A is a cellular-based, system-level power supervisory product (PMIC - Supervisors). It has been developed for single-cell and multi-cell lithium ion (Li+) battery applications, as well as single-cell LiFePo4 and lead-acid batteries. It monitors most battery chemistry types, and provides protection against overcharging and undercharging.

This device is designed to provide information and control the power supply, ensuring the battery is charged properly. The device includes multiple monitoring and protection functions, such as over-charge protection and low power/low-voltage protection. It also includes several input-output (IO) functions, such as low-voltage monitoring, battery voltage monitoring, and high-voltage monitoring.

The X40021S14IZ-A designed for automotive and consumer applications, such as digital cameras and portable devices. These applications require the ability to control and monitor a wide range of battery chemistries. The X40021S14IZ-A provides protection functions and monitoring of lithium-ion batteries, as well as a wide range of other battery chemistries. It also provides a power-on reset (POR) and System Timer-based reset circuit.

The X40021S14IZ-A features low power consumption and high accuracy monitoring. It offers several features that enable it to monitor and control multiple chemistries and provide reliable protection to the battery. These features include a wide range of input-output (IO) functions, such as low-voltage protection, overcharge protection, and low power protection. The device also includes additional system-level reset signals and adjustable thresholds.

The X40021S14IZ-A works by comparing the battery’s state of charge with the desired state of charge through the monitoring functions. When the current level of the battery is above or below the desired level, the X40021S14IZ-A can take action to protect the battery. This action may be to cut off the power supply to prevent over-charging or under-charging. This action also can be used to prevent battery damage caused by excessive charging currents.

The device can also be used as a power source selector, allowing it to select the most efficient power source. This feature helps the device deliver efficient, cost-effective system performance. It also includes a battery integration logic, which can be used to control the charging process. This integration logic allows the device to select the most efficient charging process while maximizing battery life.

The X40021S14IZ-A also features an adjustable voltage/current threshold setting. This allows the application to set the threshold level for the over-charge protection or under-charging protection. This feature can be used to ensure the battery is charged properly, safely, and with the most efficient power consumption.

Overall, the X40021S14IZ-A is a powerful and highly efficient system-level power supervisory product. It is specifically designed for use in automotive and consumer applications, providing a range of features for power management and battery safety. It offers a number of input-output (IO) functions and adjustable thresholds, which allow applications to optimize the charging process and maximize battery life.
