XC6124D418MR-G

Supervisors Overview

The XC6124D418MR-G is a high-precision voltage monitor with an integrated watchdog timer, manufactured by Torex Semiconductor Ltd. It operates within a supply voltage range of 1 V to 6 V and features a fixed detection threshold of 4.1 V. The device utilizes CMOS technology for low power consumption, drawing 12 uA during operation. It provides an active-low open-drain output and includes a typical reset timeout of 400 ms. The component is housed in a compact SOT-25-5 package and supports an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer function with selectable timeout periods for system reliability monitoring.
• Features a built-in delay circuit that eliminates the need for external components to generate release delay signals.
• Includes an enable pin (EN/ENB) allowing independent control over the watchdog function while maintaining voltage detection.

Supervisors Applications

• Microprocessor watchdog monitoring and reset circuits
• Memory battery backup switching systems
• System power-on reset generation
• Power failure detection mechanisms

Supervisors Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm the exact threshold voltage and watchdog timeout period. Ensure the ordering code matches the required package type and temperature rating. Cross-reference the manufacturer's latest documentation to confirm RoHS compliance status and availability constraints before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with integrated watchdog functionality is required. It is suitable for applications needing a fixed 4.1 V threshold and a 400 ms reset timeout. Consider the low quiescent current and small SOT-25-5 footprint for space-constrained designs requiring reliable power management without external timing components.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. These devices are designed using CMOS process technology to achieve high precision and low current consumption. The series offers various fixed detect voltages and multiple watchdog timeout options, providing flexibility for diverse supervisory circuit requirements in portable and industrial electronics.

Supervisors Replacement Considerations

Check for other XC6124 variants with different threshold voltages or timeout periods if the 4.1 V / 400 ms configuration does not match the design requirements. Verify pin compatibility and electrical specifications before substituting with other PMIC supervisors from different manufacturers.
