XC6122F622ER-G

Supervisors Overview

The XC6122F622ER-G is a voltage monitor manufactured by Torex Semiconductor, designed for supervisory circuit applications. It operates within a supply voltage range of 1 V to 6 V and features a fixed threshold voltage of 2.2 V. The device utilizes an SMD/SMT installation style in a USP-6C package. It provides a CMOS open-drain output type and includes a watchdog timer function. The reset delay time is specified at 50 ms. Operating temperatures range from -40°C to +85°C. Key electrical characteristics include a maximum power dissipation of 120 mW, a working supply current of 12 uA, and a static current of 5 uA.

Supervisors Feature Summary

• Integrates a watchdog timer function for system reliability monitoring alongside standard voltage supervision capabilities.
• Features a backup switch mechanism to support battery backup operations during power transitions.
• Provides power failure detection functionality to identify abnormal supply conditions.

Supervisors Applications

• Battery-powered electronic devices requiring low standby current consumption
• Systems utilizing backup power supplies with automatic switching requirements
• Embedded circuits needing watchdog timer protection against software faults

Supervisors Procurement Notes

Verify the specific suffix ER-G corresponds to the USP-6C package and intended reel packaging configuration before ordering. Confirm that the 2.2 V threshold and 50 ms reset delay align with the target system's timing requirements. Ensure the operating temperature range of -40°C to +85°C meets environmental specifications. Cross-reference the datasheet for pinout compatibility and electrical limits to prevent integration errors.

Supervisors Selection Notes

Select this component when a dedicated watchdog timer is required alongside voltage monitoring in a compact surface-mount footprint. The USP-6C package offers a balance between size and thermal performance for moderate power dissipation. Consider the 12 uA operating current for battery life optimization. Verify that the open-drain output interface matches the logic levels of the connected microcontroller or processor input.

Supervisors Part Context

This part belongs to the XC6122 series of voltage monitors from Torex Semiconductor, which are designed for portable equipment and battery-operated systems. The series typically integrates watchdog timers and backup switches to enhance system stability. The XC6122F622ER-G specifically denotes a 2.2 V threshold variant in the USP-6C package, distinguishing it from other package types like SOT-25 or SOT-23 found in related model numbers.

Supervisors Replacement Considerations

Direct substitutes may include other XC6122 series variants with identical 2.2 V thresholds and watchdog functions, such as those in SOT-25 packages if pinout compatibility allows. Verify functional equivalence regarding reset delay times and output drive capabilities before substitution.
