The MCP111T-270E/TTVAO belongs to the PMIC (Power Management Integrated Circuit) - Supervisors family and is used in a wide array of applications. The MCP111T-270E/TTVAO supervisor is a flexible, integrated power monitor and supervisor circuit. It provides an array of features which includes overload protection and overvoltage monitoring as well as a 200mV window comparator to give an early warning of any input overvoltage or undervoltage conditions. It also features an adjustable watchdog timer to provide preventative maintenance on system functions and status. This device is suitable for applications such as industrial and automotive, point of sale systems and other general purpose power monitoring applications.

The MCP111T-270E/TTVAO works on the principle of having two fixed input voltage trip points and an adjustable voltage window. The lower voltage trip point is set to detect an undervoltage condition and the higher voltage trip point is set to detect an overvoltage condition. The adjustable voltage window between trip points allows the user to determine a voltage window in which the output will be active. When the input voltage falls outside the voltage window, the output will be disabled. Additionally, the adjustable voltage window is used to measure the offset between the two fixed input trip points.

The MCP111T-270E/TTVAO has an adjustable watchdog timer which is used to protect against system failure due to a software hang or loop. The watchdog timer can be configured to detect conditions in which a system function or status is not being updated properly and prevent further operation if such a condition is detected. Additionally, the supervisor can be used as an overload protector to protect a system from excessive current draw by disabling the output when a predetermined current threshold is exceeded.

The MCP111T-270E/TTVAO is designed for use in a wide variety of applications including industrial, automotive, point of sale systems, and many general purpose power monitoring applications. It is simple to use, reliable, and has several features which make it ideal for these types of applications. Its adjustable voltage window helps provide an early warning of any input over- or undervoltage conditions while its adjustable watchdog timer prevents any system failure due to software hangs or loops. Additionally, the device can be used as an overload protector to protect a system from excessive current draw. Overall, the MCP111T-270E/TTVAO is an ideal solution for a variety of power monitoring applications.
