MCP102T-315E/LB

Supervisors Overview

The MCP102T-315E/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 an active-low push-pull output for reliable reset signaling. The device provides a typical reset delay timer of 120 ms to ensure stable power-up conditions. It is qualified under AEC-Q100 standards for automotive applications and is available in the compact SC-70-3 surface-mount package.

Supervisors Feature Summary

• Ultra-low supply current consumption of 1.75 µA maximum in steady state
• Active-low push-pull RST pin output for direct microcontroller interfacing
• Precision voltage monitoring with a threshold near 3.08 V
• Automotive qualification compliant with AEC-Q100 reliability standards

Supervisors Applications

• Microcontroller reset supervision in battery-powered devices
• Power management circuits in automotive electronic control units
• Voltage monitoring in industrial embedded systems
• Portable equipment requiring low quiescent current operation

Supervisors Procurement Notes

Verify the specific suffix LB indicates the SC-70-3 package configuration when sourcing. Confirm the E grade corresponds to the extended temperature range of -40°C to +125°C. Ensure compatibility with AEC-Q100 requirements if used in automotive designs. Cross-reference datasheet revision history for any parameter updates prior to final implementation.

Supervisors Selection Notes

Select this component when a push-pull output is required instead of open-drain configurations found in other series members. The SC-70-3 package offers space efficiency for dense PCB layouts. Consider the 120 ms typical delay for application timing constraints. Verify that the 1 V minimum operating voltage aligns with the lowest expected supply rail during operation.

Supervisors Part Context

This part belongs to the MCP102/103/121/131 family of micropower voltage supervisors. The MCP102 variant specifically utilizes a push-pull output stage, distinguishing it from the open-drain MCP121 and MCP131 models. All variants share similar low-power characteristics and precision monitoring capabilities within the same product line.
