MCP112T-195I/TTG

Supervisors Overview

The MCP112T-195I/TTG is a micropower voltage supervisor manufactured by Microchip Technology. It operates within a supply voltage range of 1 V to 5.5 V and features an active-low push-pull output driver. The device provides a precise monitoring threshold of approximately 1.90 V with a typical reset delay timer of 120 ms. Designed for industrial applications, it functions reliably across a temperature range of -40°C to +85°C. The component is housed in a compact SOT-23-3 surface-mount package and offers ultra-low supply current consumption.

Supervisors Feature Summary

• Ultra-low supply current consumption for extended battery life
• Active-low push-pull output driver for robust signal integrity
• Integrated reset delay timer to prevent false triggering during power transitions

Supervisors Applications

• Microcontroller system supervision
• Battery-powered electronic devices
• Portable instrumentation monitoring

Supervisors Procurement Notes

Verify the specific suffix TTG confirms the SOT-23-3 surface-mount package and lead-free compliance. Ensure the I designation matches the required industrial temperature range specifications for your application environment. Cross-reference the datasheet to confirm the active-low push-pull output configuration aligns with your circuit design requirements.

Supervisors Selection Notes

Select this component when a low-cost, low-power solution is required for systems operating between 1 V and 5.5 V. The push-pull output eliminates the need for external pull-up resistors, simplifying board layout. Consider the 120 ms reset delay to ensure stable operation during power-up sequences. Verify that the 1.9 V threshold accurately monitors the target rail voltage.

Supervisors Part Context

This part belongs to the MCP112 series of micropower voltage supervisors from Microchip Technology. It shares functional similarities with other members like the MCP121 and MCP131 but differs in output stage configuration. While the MCP121 uses an open-drain output, the MCP112 utilizes a push-pull driver, offering different interface capabilities for connected logic circuits.

Supervisors Replacement Considerations

Direct substitutes include MCP112T-195I/LBG and MCP112T-195I/TO, which share identical electrical characteristics. Variants such as MCP112T-195I/TT may differ only in packaging or reel specifications. Confirm pinout compatibility before substitution.
