XC6122D644ER-G

Supervisors Overview

The XC6122D644ER-G is a high-precision voltage detector with a watchdog timer manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.0 V to 6.0 V and features a fixed detection threshold of 4.4 V. The device utilizes CMOS technology, drawing a typical operating current of 12 µA and a standby current of 5 µA. It provides an N-channel open-drain output that goes low upon detection. The integrated watchdog timer offers selectable timeout periods ranging from 50 ms to 1.6 s, while the release delay time can be configured between 3.13 ms and 400 ms. The component is housed in a compact 6-USP (1.8x2 mm) package.

Supervisors Feature Summary

• Integrates a watchdog timer function with selectable timeout periods for system monitoring
• Features an EN/ENB pin allowing independent control over the watchdog function state
• Utilizes laser trimming technology to ensure high-precision detection voltage accuracy
• Provides built-in delay circuits eliminating the need for external components

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 corresponds to the USP-6C package and tape & reel packaging configuration. Confirm the detection voltage code matches the required 4.4 V threshold for the target application. Ensure compatibility with the -40°C to +85°C industrial temperature range specifications before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with integrated watchdog functionality is required. The 4.4 V threshold suits applications monitoring standard logic or power rails. Consider the 6-USP package size for space-constrained designs. Verify that the open-drain output interface aligns with the downstream microcontroller or logic input requirements.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. The 'XC6122' designation indicates the inclusion of a watchdog timer function, distinguishing it from the basic XC6121 series. The suffix 'D644' specifies the internal laser-trimmed detection voltage level, while 'ER-G' denotes the specific package type and environmental compliance status.

Supervisors Replacement Considerations

Cross-reference with other XC6122 variants sharing the same 4.4 V detection threshold and USP-6C package. Verify functional equivalence regarding watchdog timeout options and EN/ENB pin behavior. Ensure replacement parts maintain identical electrical characteristics and thermal performance limits.
