MCP102T-475E/LB Description

The MCP102T-475E/LB from Microchip Technology is a single-channel voltage supervisor IC designed for precision monitoring of power supply voltages in electronic systems. Packaged in a compact SC70-3 surface-mount form factor, this supervisor ensures reliable system reset functionality with a fixed threshold voltage of 4.63V, making it ideal for applications requiring tight voltage tolerance. The device features an active-low reset output and a guaranteed 80ms minimum reset timeout, ensuring stable operation during power-up, power-down, or brownout conditions. Compliant with ROHS3 and REACH environmental standards, it is suitable for industrial, automotive, and consumer electronics applications.

MCP102T-475E/LB Features

• Fixed Threshold Voltage: Precisely monitors 4.63V supplies with high accuracy.
• Active-Low Reset Output: Provides a clear reset signal for microcontroller or FPGA initialization.
• 80ms Minimum Reset Timeout: Ensures sufficient stabilization time for downstream circuits.
• Surface-Mount SC70-3 Package: Space-efficient for compact PCB designs.
• Wide Operating Range: Suitable for industrial and automotive environments.
• RoHS3 & REACH Compliant: Meets stringent environmental regulations.
• Moisture Sensitivity Level (MSL) 1: Unlimited shelf life and compatibility with standard reflow processes.

MCP102T-475E/LB Applications

• Microcontroller Reset Circuits: Ensures reliable startup and shutdown sequencing in embedded systems.
