AZ7025ZTR-E1

Power management integrated circuits (PMICs) provide electronic equipment with the precise electrical power they need to run efficiently. They are designed to ensure that equipment and system performance is not compromised by fluctuating voltage levels or unexpected power outages. Supervisors are an essential part of PMICs, designed to protect integrated circuits from overvoltage and current, as well as resetting circuitry and other components in the event of a fault. The AZ7025ZTR-E1 is a supervisor specifically designed for smart phones and is capable of protecting devices against overvoltage and overcurrent. This article will discuss the application field and working principle of the AZ7025ZTR-E1.

Applications

The AZ7025ZTR-E1 is a microcontroller-based supervisor typically used in smart phones and other mobile devices. It provides protection from voltage and current fluctuations, insulation and surge protection, as well as providing resetting capabilities in the event of a fault. It is often used in conjunction with other components such as switches, timers, and control circuitry to provide comprehensive power management. The device is also capable of monitoring the temperature of the system and can shut down the system if temperatures exceed safe levels.

Working Principle

The AZ7025ZTR-E1 is designed to protect a device’s integrated circuits from overvoltage and overcurrent. It utilizes two main components to achieve this; an attenuator and a comparator. The attenuator senses input voltage levels and adjusts the voltage or current level as appropriate. The attenuator also provides surge protection by reducing incoming voltage and current to a safe level. The comparator monitors the voltage and current levels and compares them to the allowable range. If the levels exceed this range, the comparator triggers an alarm, shutting the system down. The device also includes a temperature monitor to detect if temperatures exceed safe levels, shutting down the system if necessary.

Conclusion

The AZ7025ZTR-E1 is a PMIC supervisor designed specifically for use in smart phones and other mobile devices. It is capable of protecting devices against overvoltage and current, as well as resetting circuitry in the event of a fault. The AZ7025ZTR-E1 utilizes an attenuator and a comparator to monitor and adjust voltage levels and a temperature monitor to shut down the system if temperatures are too high. This makes it an essential part of any power management system in smart phones and other mobile devices.
