XC6122D629ER-G

Supervisors Overview

The XC6122D629ER-G is a single-channel voltage monitor and watchdog timer from Torex Semiconductor. It operates within a supply voltage range of 1 V to 6 V, featuring a fixed detection threshold of 2.9 V. The device incorporates a CMOS open-drain output and provides a reset delay time of 100 ms. It includes power failure detection and battery backup switch functions. The component consumes a typical operating current of 12 uA and a static current of 5 uA. It supports manual reset input absence and is housed in a 6-USPC package with an exposed pad.

Supervisors Feature Summary

• Integrates voltage monitoring with watchdog timer functionality for system reliability
• Features low power consumption suitable for battery-operated applications
• Includes power failure detection and battery backup switching capabilities

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Embedded systems needing voltage supervision and watchdog protection
• Battery-powered equipment with backup power switching requirements

Supervisors Procurement Notes

Verify the specific suffix ER-G against official Torex documentation to confirm the 6-USPC package type and pinout configuration. Ensure compatibility with your PCB footprint design. Cross-reference the datasheet for thermal dissipation limits and operating temperature ranges to validate suitability for your specific environmental conditions before finalizing procurement.

Supervisors Selection Notes

Select this component when a combined voltage supervisor and watchdog timer is required in a compact surface-mount package. The 2.9 V threshold suits applications monitoring 3.3 V or similar logic levels. Consider the low quiescent current for energy-sensitive designs. Verify that the open-drain output interface aligns with your microcontroller or logic gate inputs without requiring additional pull-up components beyond standard design practices.

Supervisors Part Context

This part belongs to the XC6122 series of supervisory circuits from Torex Semiconductor. The series offers various detection voltages and package options. The XC6122D629 variant specifically denotes the 2.9 V threshold. The ER-G suffix indicates the specific packaging and tape/reel configuration. This family is designed for portable electronics and industrial control systems requiring reliable power management.

Supervisors Replacement Considerations

Check for XC6122D629MR-G if SOT-25 packaging is acceptable instead of 6-USPC. Verify functional equivalence regarding threshold voltage and reset delay. Confirm pinout compatibility for direct replacement. Review datasheets for any differences in operating current or package dimensions.
