XC6124E536ER-G

Supervisors Overview

The XC6124E536ER-G is a high-precision voltage monitor manufactured by Torex Semiconductor Ltd, designed for power supply management applications. It operates within a supply voltage range of 1 V to 6 V and features a fixed detection threshold of 3.6 V. The device incorporates a built-in watchdog timer with a typical timeout period of 200 ms and a release delay time of 50 ms. It utilizes CMOS technology to achieve low current consumption, with an operating supply current of 12 uA and a static current of 5 uA. The output driver provides an open-drain signal that goes low upon voltage detection. The component is housed in a compact 6-USPC (1.8x2 mm) surface-mount package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer function with ON/OFF control capability via the EN/ENB pin
• Utilizes laser trimming technology for internally fixed detection voltages ensuring high precision
• Features a built-in delay circuit that eliminates the need for external components for release delay timing
• Provides an open-drain output type that activates low when the monitored voltage is detected

Supervisors Applications

• Battery backup switching systems requiring precise voltage monitoring
• Embedded systems utilizing watchdog timers for software error recovery
• Portable electronic devices demanding low quiescent current consumption
• Power supply management circuits in industrial equipment

Supervisors Procurement Notes

Verify the specific suffix ER-G against the manufacturer's official datasheet to confirm the 6-USPC package configuration and exact electrical parameters. Ensure compatibility with the target application's voltage levels and thermal requirements before procurement. Cross-reference the part number with authorized distributors to validate authenticity and current production status.

Supervisors Selection Notes

Select this component when a fixed 3.6 V threshold with integrated watchdog functionality is required in a small footprint. Consider the 200 ms watchdog timeout and 50 ms release delay for system timing constraints. Evaluate the 12 uA operating current against battery life requirements. Confirm that the open-drain output interface matches the receiving logic level of the microcontroller or system bus.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. The XC6124 variant specifically includes a watchdog timer function controlled by an enable pin. Unlike the XC6121 series which may lack the watchdog feature, the XC6124 series offers enhanced system protection capabilities while maintaining the same low-power CMOS architecture and high-precision detection characteristics.

Supervisors FAQ

How is the watchdog timer function enabled or disabled?

The watchdog timer can be turned on or off by setting the EN/ENB pin to a high or low level, respectively, while the voltage detector remains operational.

What is the default state of the EN/ENB pin for the XC6124 series?

For the XC6124 series, the EN/ENB pin is internally pulled up to the VIN pin or pulled down to the VSS pin, allowing it to be left open if the watchdog function is used.

Does the XC6124E536ER-G require external components for delay timing?

No, the series includes a built-in delay circuit that outputs signals with the specified release delay time without requiring any external components.
