MCP103T-270E/LB

Supervisors Overview

The MCP103T-270E/LB is a micropower voltage supervisor from Microchip Technology, designed to monitor a single power supply rail. It operates within a supply voltage range of 1 V to 5.5 V and features an active-low push-pull reset output. The device triggers at a typical threshold of 2.63 V, with specific under-voltage and over-voltage thresholds of 2.591 V and 2.67 V respectively. It includes a typical 120 ms reset delay timer and consumes only 1.75 µA in steady state. Packaged in SOT-23, it supports industrial temperature ranges.

Supervisors Feature Summary

• Provides precise monitoring of a single input voltage channel with active-low push-pull reset output
• Features ultra-low supply current consumption for extended battery life applications
• Includes a built-in reset delay timer to ensure stable system recovery during power events

Supervisors Applications

• Monitoring microcontroller power supplies
• Battery-powered electronic devices
• Industrial control systems requiring voltage supervision

Supervisors Procurement Notes

Verify the exact suffix LB against official Microchip documentation to confirm package type and temperature grade. Confirm availability status as distribution data may vary. Ensure compatibility with system voltage requirements before integration.

Supervisors Selection Notes

Select this component when a low-current, single-channel supervisor with push-pull output is required. Compare with MCP102 variants if open-drain output is preferred. Verify that the 2.63 V threshold aligns with the target system's minimum operating voltage.

Supervisors Part Context

This part belongs to the MCP103 series of micropower voltage supervisors. It shares core functionality with other members like MCP103T-270E/TTG but differs in packaging and temperature rating. The series is designed for cost-sensitive applications requiring reliable power management.

Supervisors Replacement Considerations

MCP103T-270E/TTG offers similar electrical characteristics but may differ in package or temperature specification. Verify pinout and electrical parameters before substitution.
