XC6124D725ER-G

Supervisors Overview

The XC6124D725ER-G is a high-precision voltage detector with a watchdog function from the Torex XC6124 series. It operates within a supply voltage range of 1 V to 6 V and features a fixed detection threshold of 2.5 V. The device utilizes CMOS technology for low current consumption, with a typical operating current of 12 µA and static current of 5 µA. It provides an N-channel open-drain output that goes low upon detection. Key timing parameters include a reset delay time of 50 ms and a watchdog timeout period of 800 ms. The component is housed in a 6-USPC (1.8x2) package and supports an operating 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.
• Features internally fixed detect voltages determined by laser trimming technology.
• Includes a built-in delay circuit to generate release delay signals without external components.
• Provides power failure detection and system power-on reset capabilities.

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix ER-G against the official datasheet to confirm the package type and lead time requirements. Ensure the order quantity aligns with standard packaging configurations. Cross-reference the part number with the manufacturer's latest documentation to confirm availability status and RoHS compliance details before finalizing procurement.

Supervisors Selection Notes

Select this component when a precise 2.5 V threshold is required for single-input voltage monitoring. The integrated watchdog function eliminates the need for external timers, simplifying board design. Consider the 6-USPC package size for space-constrained applications. Verify that the 12 µA operating current meets the system's power budget constraints during active monitoring phases.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. The series shares common architectural features including CMOS process technology and internal reference voltage sources. The XC6124 variant specifically incorporates the watchdog function and ON/OFF control pin, distinguishing it from basic voltage detectors in the same family.

Supervisors Replacement Considerations

Other parts in the XC6124 series with different threshold voltages or package options may serve as functional substitutes if electrical parameters match. Verify compatibility of the watchdog timeout settings and output configuration before substitution.

Supervisors FAQ

How is the watchdog function controlled?

The watchdog function 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, the EN/ENB pin is internally pulled up to the VIN pin or pulled down to the VSS pin, allowing the IC to be used with the pin left open when the watchdog function is utilized.

Does the device require external components for delay generation?

No, the built-in delay circuit allows the IC to output signals with release delay time without requiring any external components.
