XC6123A425ER-G

Supervisors Overview

The XC6123A425ER-G is a high-precision voltage monitor manufactured by Torex Semiconductor, designed for supervisory circuit applications. It operates within a supply voltage range of 1 V to 6 V and features a fixed detection threshold of 4.25 V. The device incorporates a built-in watchdog timer and utilizes a CMOS process technology to achieve low current consumption, with a typical operating current of 12 µA and static current of 5 µA. It provides an open-drain output configuration and includes a reset delay time of 3.13 ms. The component is housed in a 6-USPC (1.8x2 mm) surface-mount package and supports an industrial 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
• Utilizes laser trimming technology to ensure high precision in fixed detection voltage settings

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix codes against official datasheets to confirm exact threshold voltages and package variations. Ensure compatibility with required operating temperatures and supply voltage ranges before integration. Cross-reference manufacturer part numbers with distributor listings to confirm availability and authenticity. Check for RoHS compliance status if environmental regulations apply to the target application.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with integrated watchdog functionality is required. The 4.25 V threshold suits applications monitoring standard logic or memory supply rails. Consider the low quiescent current for battery-powered designs. Verify that the open-drain output interface matches the downstream microcontroller or logic input requirements.
