Introduction

The S-80953CLNB-G7PT2U is a supervisor integrated circuit (IC) which belongs to “PMIC - Supervisors” product family. It works as a reset controller to provides reset signal when system enters abnormal status or user requests reset. It is widely used in various systems, such as mobile phones, servers, automotive display systems and many more. The following sections will discuss in detail the application field and working principle of the S-80953CLNB-G7PT2U PMIC - Supervisors.

Application Field

S-80953CLNB-G7PT2U has a wide range application in different areas due to its versatile features.

• Mobile phones
  The S-80953CLNB-G7PT2U is widely used in mobile phones or any portable electronic devices. It is designed to provide reset when the system experiences power failure or abnormal status. It also provides a function to generate reset signal through software control, which is important for the portable device like mobile phone, since it supports the recovery of system when the system encounters some errors.
• Servers
  The S-80953CLNB-G7PT2U can provide reset signal when the server experiences power failure or system error, thus helping to prevent data loss. The reset signal generated by the S-80953CLNB-G7PT2U can also help to restart the server, so that it can keep normal operation.
• Automotive display systems
  The S-80953CLNB-G7PT2U integrated circuit helps to reset the automotive display system. When the system experiences some errors, the reset signal can be generated to reset the system and provide clean power for a smooth operation.
• Other applications
  Apart from the above applications, S-80953CLNB-G7PT2U PMIC - Supervisors also has various other applications, such as digital TV, digital video recorder, point of sales machines, mobile POS terminals and many more.

Working Principle

The S-80953CLNB-G7PT2U works as a reset controller which provides reset signal when certain conditions are met. It has on-chip voltage detector which can detect when voltage dropped or rises above the predefined threshold level. When this occurs, the S-80953CLNB-G7PT2U will generate a reset signal to reset the reloaded address pointer and memory state. The reset signal can be generated either manually by pressing a button, or through software control.The S-80953CLNB-G7PT2U is also able to detect the current status of the system using a programmable timer which can be configured to terminate or suspend the reset signal based on a predefined amount of time. In addition, the S-80953CLNB-G7PT2U also supports an input timeout feature which can generate reset signal if there is no activity for a certain period of time. Lastly, there is also an adjustable voltage subject monitor which can detect when the voltage supplied drops below a preset value and generates reset signal if it is necessary.

Conclusion

In conclusion, the S-80953CLNB-G7PT2U PMIC - Supervisors is a reset controller which provides reset signal when certain conditions are met. It has wide range application in different areas such as mobile phones, servers, automotive display systems and many more. Finally, it has several functions, such as voltage detector, adjustable voltage threshold and programmable timer, which allow it to support different types of reset signal generation.
