XC6123C649ER-G

Supervisors Overview

The XC6123C649ER-G is a high-precision voltage detector with an integrated watchdog timer manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.0V to 6.0V and features a fixed detection threshold of 4.9V. The device utilizes CMOS technology for low power consumption, with a typical operating current of 12µA and standby current of 5µA. It provides a watchdog timeout period of 800ms and a release delay time of 200ms. The output configuration is an N-channel open-drain structure that goes low upon detection. It is housed in a compact 6-USP (1.8x2) surface-mount package and supports an operating temperature range from -40°C to +85°C.

Supervisors Procurement Notes

Verify the specific suffix ER-G against the official datasheet to confirm the package type and tape & reel packaging details. Ensure the detection voltage code matches the required 4.9V threshold for your application. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and availability.

Supervisors Selection Notes

Select this component when a precise 4.9V monitoring level is required alongside watchdog functionality. The 6-USP package is ideal for space-constrained designs. Consider the 800ms timeout and 200ms delay settings to match system timing requirements. Verify that the open-drain output interface is compatible with the downstream logic levels. Ensure the operating temperature range meets environmental specifications.

Supervisors Part Context

This part belongs to the XC6123 series of voltage detectors with watchdog functions. The series employs CMOS process technology and offers various detection voltages from 1.6V to 5.0V in 100mV increments. Different suffixes indicate variations in package style and watchdog timing configurations. The XC6123C649ER-G specifically denotes the 4.9V threshold variant in the USP-6C package.

Supervisors FAQ

How is the watchdog function controlled?

The watchdog function can be turned ON or OFF independently of the voltage detector by setting the EN/ENB pin to a high or low level.

What is the output state when the detected voltage falls below the threshold?

The output goes low (VDFL) when the input voltage is detected as lower than the threshold voltage.
