Introduction

The S-1000N38-I4T1U is a power management IC (PMIC) with a supervisor-based solution that helps protect electrical systems from damage due to excessive power consumption or overcurrent conditions. The supervisor offers robust safety control functions and allows for up to four independent threshold levels to be configured, allowing the user to tailor the application’s performance to their specific needs. Furthermore, the device can detect temperature changes, quickly response to over-current conditions, and offers fault-signalling capabilities. This makes the S-1000N38-I4T1U a suitable choice for applications such as automotive electronics, industrial equipment, and LED lighting, in addition to being suitable for very low power applications.

Application Field

The S-1000N38-I4T1U application fields range from automotive electronics to industrial equipment and LED lighting. This PMIC can be used to protect electrical systems in automotive, industrial, or medical equipment from damage caused by over-voltage, over-current, or temperature variations. Its robust safety-control functions, including four configurable thresholds, make it ideal for environment where a reliable and secure power-management system is required.The device can operate on a supply voltage ranging from 4.4V to 85V and features a 22µA quiescent current, which makes it suitable for very low power applications. Furthermore, its temperature sensing capabilities can detect sudden increases in temperature and quickly react, providing an extra layer of protection to the electrical system.

Working Principle

The S-1000N38-I4T1U works by utilizing four independent configurable thresholds to accurately control and monitor current and voltage levels in an electrical system. The range for these thresholds is -2.5V to +5.5V, allowing for a versatile solution that can be tailored to specific applications.When the voltage or current exceeds one of the configured thresholds, the supervisor switches off the load to limit the amount of current travelling through it. Additionally, the device will signal any over-current or over-voltage fault via an open Drain output, which can be used to alert user to a system malfunction. The device also has a temperature sensing feature, which is especially useful when used with automotive solutions and medical devices. When the temperature rises beyond the pre-defined threshold, the supervisor will switch off the load and send an alert signal to the user.

Conclusion

The S-1000N38-I4T1U PMIC with supervisor-based solution is a suitable choice for applications such as automotive electronics, industrial equipment, and LED lighting, in addition to being suitable for very low power applications. By utilizing four configurable thresholds, the device is able to accurately control and monitor current and voltage levels in an electrical system, and its temperature sensing capabilities offer an extra layer of protection.
