PMIC (Power Management Integrated Circuit) has seen an increasing demand as a result of the growth of sophisticated mobile devices. Supervisors are a subclass of PMIC specifically optimized to predict, detect, and protect against faults in the voltage supply circuit of your embedded application. The MCP111T-290E/LB supervisor is one such example of a high performing supervisor that provides reliable system protection.

Overview

The MCP111T-290E/LB is a single-chip supervisor designed for accurate voltage monitoring of embedded applications such as mobile and desktop computers, industrial control systems and other embedded applications. It can be used to detect any discrepancies between the expected voltage level and real-time input voltage, and alert the application for corrective action.

The MCP111T-290E/LB supervisor provides voltage monitoring in multiple configurations depending on your application. It is available in an 8-lead PDIP (Plastic Dual-In-Line) package and a 6-lead SOT (Small Outline Transistor) package. It can be used to monitor single, dual, or triple voltages and includes a manual reset (MR) feature.

Application Field

The MCP111T-290E/LB supervisor can be used for a wide range of embedded applications featuring single, dual, and triple voltage systems. It is commonly used for monitoring low voltages such as 1.8V, 2.5V, 3.3V, and 5V. It can be used in mobile devices, personal computers, embedded controllers, automotive systems, industrial control systems, or any application requiring reliable voltage monitoring.

Working Principle

The MCP111T-290E/LB supervisor functions by comparing the real-time feedback voltage to the preset threshold levels (1.2V, 1.8V, 2.5V, 3.3V, and 5V). Once the feedback voltage matches the preset levels, the supervisor will be triggered, and a reset or active low signal will be issued. This signal can then be used to alert the application of any discrepancies between the expected voltage level and the real-time voltage level.

The manual reset (MR) feature allows users to manually reset the supervisor if necessary. The resetting is done by manually pulling the MR pin to a low voltage level for a period of time that is specified in the datasheet. The supervisor can be reset by either pulling the MR pin to a low voltage level for the specified period of time or by removing the VDD input voltage for the same period of time.

The MCP111T-290E/LB supervisor utilizes a robust design and advanced technologies to ensure reliable protection against voltage fluctuations. It features a low power operation of 1µA typical, a 5µs protection window, and a wide operation temperature range of -40°C to +125°C. The supervisor also includes built-in protection against damage from excessive input voltage, reverse polarity, and power-up transients.

Conclusion

The MCP111T-290E/LB supervisor is a highly reliable solution for monitoring voltages in single, dual, or triple voltage systems. Its robust design, wide operation temperature range and protection against power-up transients make it an ideal choice for a wide range of embedded applications. As a result, the MCP111T-290E/LB supervisor is an essential component for providing reliable system protection.
