Microchip Micropower Voltage Supervisor MCP102T-195I/TT 1 Supervisor, Active Low Output, SOT-23 Package

Microchip MCP102T-195I/TT is a reliable micropower voltage supervisor IC tailored for industrial, electronic components, and power management applications. It monitors the supply voltage to microcontrollers or other critical devices, holding them in reset during brownout or power-fail conditions. This device ensures system stability by using an active low push-pull reset pin and a reset delay timer of approximately 130 milliseconds.

The supervisor operates within a supply voltage range of 1 V to 5.5 V and features an ultra-low supply current of 1.75 μA, minimizing power consumption during steady-state operation. It is designed for surface-mount applications with a compact 3-pin SOT-23 package measuring 3.04 mm in length, 1.4 mm in width, and 1.02 mm in height, allowing efficient PCB space usage.

Its operating temperature range from -40°C up to 85°C makes it suitable for harsh environments, including industrial, automotive systems (though not qualified to automotive standard), and embedded electronics. The monitored voltage threshold is set at 1.9 V, suitable for low-voltage system supervision.

This device features power-fail detection capabilities to detect supply voltage drops, preventing uncontrolled microcontroller operations. The active low RST output provides a direct interface to microcontrollers with push-pull output for clean reset signaling.

Applications include microcontroller reset circuitry, power management in embedded systems, battery-backed equipment, and industrial automation systems requiring precise voltage supervision.
