XC6124C446ER-G

Supervisors Overview

The XC6124C446ER-G is a high-precision voltage detector with watchdog functionality manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.0 V to 6.0 V and features a fixed detection threshold of 4.6 V. The device utilizes CMOS technology, consuming a typical operating current of 12 µA and a standby current of 5 µA. It provides an open-drain output for low-active reset signals. The integrated watchdog timer offers selectable timeout periods ranging from 50 ms to 1.6 s, while the release delay circuit provides five selectable timing options from 3.13 ms to 400 ms. The component is housed in a compact 6-USPC (1.8x2) surface-mount package and supports an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer function with selectable timeout periods to monitor system software execution integrity.
• Features an internal delay circuit that generates release delay times without requiring external components.
• Includes an EN/ENB pin allowing independent control to disable 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

Supervisors Procurement Notes

Verify the specific suffix ER-G corresponds to the 6-USPC tape-and-reel packaging configuration. Confirm the detection voltage code aligns with the required 4.6 V threshold for the target application. Ensure the selected variant matches the necessary watchdog timeout and release delay specifications defined in the official datasheet before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 4.6 V detection threshold is required for single-channel voltage supervision. Consider the integrated watchdog feature if system stability monitoring is needed alongside power management. Evaluate the 6-USPC package dimensions against available PCB space constraints. Verify that the open-drain output interface is compatible with the downstream logic levels of the controlled microcontroller or peripheral devices.

Supervisors Part Context

This part belongs to the XC6124 series of voltage detectors produced by Torex Semiconductor. The series is characterized by high precision and low current consumption, utilizing laser trimming technology to set detection voltages in 0.1 V increments between 1.6 V and 5.0 V. The XC6124 variants specifically incorporate watchdog functions and ON/OFF control capabilities, distinguishing them from basic voltage monitors within the broader product family.

Supervisors Replacement Considerations

Cross-reference other XC6124 series part numbers with different detection voltage codes (e.g., XC6124C440, XC6124C442) if the threshold requirement differs. Verify compatibility with alternative packages such as SOT-25-5 if board layout changes are permitted. Ensure any substitute maintains the same 1.0 V to 6.0 V operating voltage range and industrial temperature specifications.
