XC6123C531MR-G

Supervisors Overview

The XC6123C531MR-G is a voltage monitor IC from Torex Semiconductor, packaged in an SOT-25-5 surface-mount case. It monitors a single input channel with a threshold voltage of 3.1V. The device features an open-drain output type and includes a watchdog timer function. The reset timeout is typically 400 ms, with a reset delay time of 50 ms. It operates within a supply voltage range up to 6V and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer circuit for system reliability monitoring
• Provides open-drain output configuration for flexible interface compatibility
• Supports battery backup switching functionality

Supervisors Applications

• Embedded system power supervision
• Microcontroller reset management
• Battery-operated device monitoring

Supervisors Procurement Notes

Verify the specific threshold voltage (3.1V) and package variant (SOT-25-5) against project requirements. Confirm that the open-drain output logic aligns with the target system's input specifications. Ensure the operating temperature range meets environmental conditions. Cross-reference the manufacturer part number with official distributor catalogs to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a dedicated watchdog timer with a fixed 3.1V threshold is required. The SOT-25-5 package suits space-constrained designs. Consider the open-drain output if external pull-up resistors are acceptable or necessary for level shifting. Verify that the 400 ms reset timeout fits the application's fault detection timing constraints.
