XC6124F639ER-G

Supervisors Overview

The XC6124F639ER-G is a high-precision voltage detector with a watchdog function manufactured by Torex Semiconductor. It operates within a supply voltage range of 1 V to 6 V and features a fixed detect voltage of 3.9 V, determined by laser trimming technology. The device incorporates an N-channel open-drain output configuration and includes a built-in delay circuit for release delay times ranging from 3.13 ms to 400 ms. Six selectable watchdog timeout periods are available, spanning from 50 ms to 1.6 s. The EN/ENB pin allows control over the watchdog function state. It 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 with selectable timeout periods and a built-in release delay circuit requiring no external components.
• Features an EN/ENB pin that enables or disables the watchdog function while maintaining voltage detection operation.
• Utilizes laser trimming technology to provide internally fixed detect voltages with high precision across a wide range.

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 package type and lead-free status. Ensure the detect voltage code matches the required 3.9 V threshold for your design. Cross-reference the EN/ENB pin internal pull-up configuration with your system logic levels. Confirm availability through authorized distributors as standard delivery times may vary.

Supervisors Selection Notes

Select this component when a precise 3.9 V threshold is required alongside integrated watchdog functionality. The 6-USPC package suits space-constrained surface-mount designs. Consider the low current consumption and wide operating voltage range for battery-powered applications. Verify that the available watchdog timeout options align with the microprocessor's timing requirements.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. The series utilizes CMOS process technology to achieve high precision and low current consumption. These ICs combine reference voltage sources, delay circuits, comparators, and output drivers into a single unit, simplifying system design by eliminating the need for external timing components.

Supervisors FAQ

How is the watchdog function controlled on the XC6124F639ER-G?

The watchdog function can be turned ON or OFF by setting the EN/ENB pin to a high or low level. For this series, the EN/ENB pin is internally pulled up to the VIN pin, allowing it to be left open if the watchdog function is used.

What is the output configuration of the XC6124F639ER-G?

The output configuration is an N-channel open drain. The output goes low when a detected voltage condition is met.
