MCP102T-195I/LB

Supervisors Overview

The MCP102T-195I/LB is a micropower voltage supervisor manufactured by Microchip Technology, designed to monitor system power integrity. It operates within a supply voltage range of 1 V to 5.5 V and features a precise reset threshold voltage of 1.90 V. The device utilizes an active-low push-pull output driver to assert a reset signal during power-loss events. It incorporates a typical reset delay timer of 120 ms to ensure stable operation before releasing the reset state. The component is housed in a compact SC-70-3 surface-mount package and supports industrial temperature operation from -40°C to +85°C.

Supervisors Feature Summary

• Ultra-low supply current consumption for extended battery life
• Active-low push-pull output driver for robust logic interfacing
• Integrated reset delay timer prevents premature reset release

Supervisors Applications

• Microcontroller power supply monitoring
• Battery-powered embedded systems
• Portable electronic devices requiring low quiescent current

Supervisors Procurement Notes

Verify the specific suffix 'LB' corresponds to the SC-70-3 package configuration as documented in official datasheets. Confirm that the 'I' designation aligns with the required industrial temperature range specifications for your application environment. Ensure compatibility with the active-low push-pull output requirements of the target circuit design.

Supervisors Selection Notes

Select this component when a low-cost, micropower solution is required for single-voltage monitoring. The push-pull output architecture offers stronger drive capability compared to open-drain alternatives, suitable for direct connection to digital inputs without external pull-up resistors. Consider the 1.90 V threshold specifically for 1.8 V or 2.0 V logic families.

Supervisors Part Context

This part belongs to the MCP102/103/121/131 family of micropower voltage supervisors. While sharing similar core functionalities such as low current consumption and reset delay timers, variants differ in output driver types (push-pull vs. open-drain) and available packages. The MCP102 series specifically denotes the active-low push-pull output configuration.
