A supervisor IC is an integrated circuit designed to monitor power supplies, system parameters and other important operating conditions. The S-1003NA40I-I6T1U is a power supervisor IC from the S-1003 family. It is designed to supervise the supply voltage lines of microcontroller and other digital systems, to provide power-fail warning and disable functions, and output reset signals. In this article, we’ll take a closer look at the S-1003NA40I-I6T1U’s application field and working principle.

Application Field: The S-1003NA40I-I6T1U is ideal for microcontrollers and other digital systems. It is compatible with various voltage levels from 2.3V to 3.6V, making it suitable for a wide range of applications. The S-1003NA40I-I6T1U also features a low operating supply current of less than 0.3µA, allowing it to operate efficiently in many systems.

The device features over-voltage and under-voltage protection, which ensures that the system operates within the prescribed voltage parameters. It also has an auto restart function which can be enabled or disabled by sensing signals from other parts of the system. The S-1003NA40I-I6T1U also has an active high reset and reset enable control inputs, allowing it to be configured to restart the system or issue a system reset.

Working Principle: The S-1003NA40I-I6T1U continuously monitors the voltage level of the input supply voltage and makes sure that it does not deviate from the preset limits. It contains an internal comparator which compares the input voltage level with the preset voltage levels and if the levels exceed or fall below the permissible limits, it sends out a power-fail warning. If the power-fail warning remains active for a preset amount of time, the S-1003NA40I-I6T1U will output the reset signal, resetting the system.

The device features a wide operating temperature range so that it can be used in a variety of operating environments. It also has a low input voltage detection and low operating supply current which make it suitable for low power applications. In addition, the S-1003NA40I-I6T1U has an integrated output disable circuit which allows it to be used as an on/off switch for the system.

The S-1003NA40I-I6T1U is a versatile power supervisor IC for microcontroller systems and other digital systems. It has a wide voltage range, low operating supply current and built-in reset circuits which makes it suitable for monitoring power supplies, system parameters and other important operating conditions.
