PMIC - Supervisors are a type of integrated circuit designed to provide a complete power management solution. In this application note, we will discuss the S-80128ANMC-JCNT2U, specifically its application field and working principle.

S-80128ANMC-JCNT2U Overview

The S-80128ANMC-JCNT2U is a highly integrated PMIC supervisor from Sumitomo Electric Components. It is designed to protect systems from potentially damaging overvoltage and undervoltage events in automotive applications.

The device has a wide operating voltage range of 36V-42V and supports a maximum current of 30A. It provides excellent circuit protection by monitoring the state of the battery and shutting off any abnormal current. It also features low power consumption and has a thermally efficient package size.

The S-80128ANMC-JCNT2U has been designed to provide a highly sensitive and reliable voltage supervision. It is also able to detect fluctuations in the current and rapidly respond to them by carrying out the appropriate protective action.

In addition, the device can be customized with external resistors to meet the specific requirements of different application domains.

S-80128ANMC-JCNT2U Application Field

The S-80128ANMC-JCNT2U is designed for automotive applications. It provides effective protection against both high and low voltage conditions and can be used in a range of applications, such as solar cells, power inverters, battery chargers, and electric vehicle charging stations, where accuracy and precision are required to ensure the safety of the system and the people using it.

The device is particularly well suited for electric vehicles, as it can provide protection against sudden voltage drops and overvoltage states. It is also able to detect and respond to fluctuations in the current and take appropriate protective measures if required.

S-80128ANMC-JCNT2U Working Principle

The S-80128ANMC-JCNT2U is an open-loop voltage supervisor. It uses a comparator circuit to measure the voltage across two external terminals and compares the measured voltage to a preset trip level. If the voltage exceeds the preset trip level, the device will actuate a protection circuit to shut off the power supply.

The device also comes with an output based reference voltage that can be used to provide certain control functions. The reference voltage is adjustable using external resistors and is used to trip the voltage supervisor if the voltage at the input becomes too high or too low.

Furthermore, the device has a lockout feature that prevents any further action until the predetermined voltage is restored. This feature ensures that the protection circuit is not activated when the voltage is within the acceptable range.

In addition, the S-80128ANMC-JCNT2U has a highly accurate monitoring system that is capable of detecting and responding to fast voltage fluctuations within a few microseconds. This ensures that the power supply is immediately shut off if the voltage reaches a dangerous level.

Conclusion

The S-80128ANMC-JCNT2U is a highly effective and reliable PMIC supervisor for automotive applications. It provides excellent protection against high and low voltage states and is able to detect and respond to fast voltage fluctuations. The device is customizable and supports a wide operating voltage range and current of up to 30A.
