XC6122D448ER-G

Supervisors Overview

The XC6122D448ER-G is a high-precision voltage detector with a watchdog timer manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.0 V to 6.0 V and features a fixed detection threshold of 4.8 V. The device utilizes CMOS technology, drawing a typical operating current of 12 µA and a standby current of 5 µA. It provides an N-channel open-drain output and includes a built-in delay circuit for release timing. The component is housed in a 6-USPC (UFDFN) package with exposed pads.

Supervisors Feature Summary

• Integrates a watchdog timer function with selectable timeout periods ranging from 50 ms to 1.6 s.
• Features an EN/ENB pin that allows independent control of the watchdog function while maintaining voltage detection operation.
• Utilizes laser trimming technology to ensure high precision in the internally fixed detection voltage.
• Includes a built-in delay circuit that eliminates the need for external components to generate release delay signals.

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 'D448' corresponds to the required 4.8 V detection threshold before ordering. Confirm the ER-G suffix indicates the USP-6C package variant. Ensure compatibility with the system's voltage levels and temperature requirements (-40°C to +85°C). Cross-reference the datasheet for exact electrical characteristics and pin configurations to prevent integration errors.

Supervisors Selection Notes

Select this component when a fixed 4.8 V detection threshold is required for systems operating between 1.0 V and 6.0 V. The integrated watchdog timer simplifies design by removing external timing components. Consider the low current consumption for battery-powered applications. Verify that the open-drain output configuration matches the microprocessor input requirements.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. The XC6122 series specifically incorporates a watchdog function and ON/OFF control capabilities. These devices are designed for high-precision monitoring in industrial and consumer electronics, offering reliability through CMOS process technology and internal laser trimming for accurate voltage thresholds.

Supervisors Replacement Considerations

Other parts in the XC6122 series with different detection voltages or packages may serve as functional substitutes if the threshold voltage matches the application requirement. Verify pinout compatibility and electrical specifications before substitution.
