PMIC - Supervisors are integrated circuits which monitor and control the operation of other system components. Among them, AS1909C22-T is one of the most popular and widely used PMICs in the market. This integrated circuit has various applications in a wide range of applications, such as power management, automotive, industrial control, communication, and health care. In addition, it can be used in mobile and portable equipment. In this article, we will discuss the application field and working principle of AS1909C22-T.

The AS1909C22-T is a Supervisors IC manufactured by ASIC (Application Specific Integrated Circuit) International. It is an integrated dual-channel device which is designed to monitor and control power management supply voltage. It is an active low-voltage monitor which features an adjustable voltage threshold ranging from 4V to 6.25V. It also contains a thermal protection circuit which helps to protect the device in case of an over temperature situation. Furthermore, the device also supports various reset timing functions, such as reset by power-on, reset by watchdog timer, and reset by over temperature.

This Supervisors IC is used in various applications to monitor and control the power supply voltage. In mobile and portable devices, it can be used to protect the device in case of over temperature. Moreover, it can also be used to prevent mobile device from continuing to run if the battery is running low. Additionally, it can be used in automotive, health care, and industrial control to ensure the correct operation of system components. In the communication industry, AS1909C22-T is applied to reset servers and other communication equipment.

The working principle of AS1909C22-T is fairly simple. It is built on AHAB (Active High-current Analog Buffer) technology, which enables it to monitor two different analog input voltages at the same time. It can detect any voltage changes between its two inputs, and if the input voltage drops below its threshold voltage, it provides a reset signal to the system. This reset signal can be used to reset the device, or it can be connected to a system shutdown or warning circuit. Furthermore, the device can also be configured to provide an interrupt alert in case of an over temperature condition.

In conclusion, the AS1909C22-T is an integrated dual-channel PMIC which is applicable for a wide range of applications. It is designed to monitor and control the power management supply voltage, and provides both reset and over temperature protection functions. The device is based on AHAB technology which allows it to detect voltage changes between two different inputs and provide an alert signal when the input voltage drops below its threshold. Its diverse applications, impeccable performance, and easy integration into different systems make it one of the most popular and widely used PMICs in the market.
