XC6124A516ER-G

Supervisors Overview

The XC6124A516ER-G is a high-precision voltage detector with watchdog function from the XC6124 series by Torex Semiconductor. It operates within a supply voltage range of 1V to 6V and features a fixed detection threshold of 1.6V. The device incorporates an N-channel open-drain output and includes a built-in delay circuit for reset release timing. It supports watchdog timeout periods ranging from 50ms to 1.6s and offers release delay times from 3.13ms to 400ms. The component is available in a 6-USPC (1.8x2) package and functions across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates CMOS process technology for high-precision voltage monitoring and low current consumption.
• Includes a built-in watchdog timer that outputs a reset signal if input levels remain constant within the timeout period.
• Features an EN/ENB pin for controlling the ON/OFF state of the watchdog function while keeping the voltage detector active.

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 Torex datasheet to confirm the 6-USPC package type and tape & reel packaging configuration. Ensure the detection voltage code corresponds to the required 1.6V threshold for your application design. Cross-reference the RoHS compliance status and lead time specifications directly with authorized distributors or the manufacturer before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a 1.6V detection threshold is required for systems operating between 1V and 6V. The integrated watchdog function eliminates the need for external timing components, simplifying the circuit design. Consider the N-channel open-drain output compatibility with the target microprocessor logic levels. Verify that the 6-USPC package dimensions fit the available PCB space constraints.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors with watchdog functions. These ICs utilize laser trimming technology to fix detect voltages in increments of 0.1V within the 1.6V to 5.0V range. The series is designed for applications requiring reliable system supervision with minimal external component count.

Supervisors FAQ

How is the watchdog function controlled on the XC6124A516ER-G?

The EN/ENB pin controls the ON/OFF state of the watchdog function. Setting this pin to a low or high level can disable the watchdog while the voltage detector remains operational.

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

The EN/ENB pin of the XC6124 series is internally pulled down to the VSS pin, allowing the IC to be used with the pin left open when the watchdog function is utilized.
