XC6123C433ER-G

Supervisors Overview

The XC6123C433ER-G is a high-precision voltage detector and watchdog timer manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.0V to 6.0V with a typical quiescent current of 5µA. The device features an open-drain output and monitors a single voltage threshold set at 4.3V. It includes a built-in watchdog timer with a typical reset timeout of 100ms. The component 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 Feature Summary

• Integrates a high-accuracy voltage monitor with a dedicated watchdog timer circuit for system reliability.
• Features an open-drain output structure that allows flexible interfacing with various logic levels.
• Provides low power consumption suitable for battery-operated applications with minimal static current draw.

Supervisors Applications

• Microprocessor system supervision and reset management
• Watchdog timer circuits for embedded controllers
• Battery backup switching systems

Supervisors Procurement Notes

Verify the specific suffix 'ER' confirms the tape and reel packaging configuration required for automated assembly processes. Ensure the 4.3V threshold voltage aligns precisely with the target system's monitoring requirements. Confirm the 6-USP package dimensions match the PCB footprint design constraints before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a combined voltage supervisor and watchdog function is required in a minimal footprint. The 4.3V threshold is appropriate for monitoring standard 5V or 3.3V rail variations. Consider the open-drain output capability if level shifting or wired-OR configurations are necessary within the target circuit architecture.

Supervisors Part Context

This part belongs to the XC6123 series, which combines voltage detection with watchdog functionality. It utilizes CMOS technology for low power operation and laser-trimmed accuracy. The series is designed for industrial and commercial applications requiring reliable power management and system reset protection in compact packages.

Supervisors Replacement Considerations

Cross-reference with other XC6123 variants sharing the ER package suffix but differing in threshold voltage codes. Verify functional compatibility regarding the watchdog timeout period and output polarity before substituting with similar supervisory ICs from the same manufacturer family.
