XC6123C436ER-G

Supervisors Overview

The XC6123C436ER-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 3.6V. The device utilizes CMOS technology for low power consumption, drawing only 5µA in standby. It provides an active-low open-drain output and includes a built-in delay circuit that eliminates the need for external components. The watchdog function offers selectable timeout periods, while the EN/ENB pin allows independent control of the watchdog feature.

Supervisors Feature Summary

• Integrates a high-precision voltage detector with a dedicated watchdog timer circuit on a single chip.
• Features an active-low open-drain output driver compatible with various logic families.
• Includes an enable pin (EN/ENB) to independently switch the watchdog function without affecting voltage monitoring.
• Utilizes internal delay circuits to provide release delays and watchdog timeouts without requiring external capacitors.

Supervisors Applications

• Microprocessor system reset circuits
• Memory battery backup switching
• Power failure detection systems

Supervisors Procurement Notes

Verify the specific suffix ER-G corresponds to the USP-6C package and tape & reel packaging configuration. Confirm the C-series designation aligns with the required 3.6V threshold voltage. Ensure compatibility with the -40°C to +85°C operating temperature range for your application environment. Cross-reference the datasheet revision to confirm pinout consistency with existing designs.

Supervisors Selection Notes

Select this component when a combined voltage supervision and watchdog timer is required in a minimal footprint. The 3.6V threshold suits applications monitoring standard 3.3V or similar rail voltages. The open-drain output allows flexibility in interfacing with different logic levels. Consider the USP-6C package dimensions if board space is constrained compared to SOT-25 alternatives.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. The XC6123 variant specifically integrates the watchdog functionality alongside the voltage monitor. The 'C' in the model number typically indicates the detection voltage level, while 'ER-G' denotes the specific package type and environmental compliance status defined by the manufacturer.

Supervisors Replacement Considerations

Check XC6123C436MR-G for SOT-25-5 package alternative. Verify XC6123C436ER-G variants with different suffixes for identical electrical specifications but distinct packaging formats.
