XC6123C335ER-G

Supervisors Overview

The XC6123C335ER-G is a high-precision voltage detector with watchdog function and ON/OFF control, manufactured by Torex Semiconductor using CMOS process technology. It features an operating voltage range of 1.0V to 6.0V and a detect voltage of 3.3V. The device includes a built-in delay circuit for release delay times ranging from 3.13ms to 400ms and six watchdog timeout period settings from 50ms to 1.6s. It operates within a temperature range of -40°C to +85°C, consumes 12µA during operation and 5µA in standby, and utilizes a 6-USPC (1.8x2) package.

Supervisors Feature Summary

• Integrates watchdog timer functionality with selectable timeout periods for system monitoring
• Provides independent ON/OFF control of the watchdog function via EN/ENB pin while maintaining voltage detection
• Utilizes laser trimming technology for fixed internal detect voltage settings without external components
• Features N-channel open drain output configuration with built-in release delay circuit

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix ER-G against official Torex documentation to confirm the USP-6C package type and ensure compatibility with surface mount assembly processes. Confirm that the 3.3V threshold aligns with target supply rails. Cross-reference the datasheet revision date to validate electrical characteristics such as current consumption and temperature coefficients before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when precise voltage monitoring with integrated watchdog capabilities is required for low-power applications. The 3.3V threshold suits standard logic levels, while the open-drain output allows flexible interfacing. Consider the 12µA operating current for battery-sensitive designs and verify that the available watchdog timeouts match the processor's clock cycle requirements for reliable fault detection.

Supervisors Part Context

This part belongs to the XC6123 series of voltage detectors, which are designed for high-precision monitoring in industrial and consumer electronics. The series distinguishes itself by incorporating watchdog functions directly into the voltage detector IC, reducing external component count. The XC6123 variant specifically offers ON/OFF control for the watchdog feature, providing greater flexibility in system power management compared to basic monitors.

Supervisors Replacement Considerations

Direct substitutes include other XC6123 series variants with matching 3.3V thresholds and compatible packages, such as XC6123C335MR-G for SOT-25 packaging. Ensure any replacement maintains the same watchdog timeout options and EN/ENB pin functionality to preserve system behavior without redesign.
