XC6121E633ER-G

Supervisors Overview

The XC6121E633ER-G is a high-precision voltage detector with a watchdog function manufactured by Torex Semiconductor Ltd. It operates within a supply voltage range of 1.6V to 5.0V and features a fixed detection threshold of 3.3V. The device incorporates a CMOS process for low current consumption, typically 12µA. It includes an internal delay circuit providing a release delay time of 200ms without external components. The output driver is open-drain type, active low. It supports ON/OFF control via the EN/ENB pin and offers protection against power failure. The component is housed in a compact 6-USPC (1.8x2mm) package.

Supervisors Feature Summary

• Integrates a watchdog timer function with built-in delay circuit for system monitoring
• Features low current consumption utilizing advanced CMOS process technology
• Provides open-drain output with active-low signal when detection occurs
• Includes enable control pin for managing watchdog functionality on/off states

Supervisors Applications

• Microprocessor reset circuits requiring watchdog supervision
• Battery-powered devices needing low quiescent current monitoring
• Portable electronic equipment with strict space constraints
• Industrial control systems requiring reliable voltage supervision

Supervisors Procurement Notes

Verify the specific suffix ER-G indicates the correct tape and reel packaging configuration. Confirm the detection threshold matches the required 3.3V application point. Ensure the operating temperature range of -40°C to +85°C aligns with environmental requirements. Check RoHS compliance status for regulatory adherence. Validate the 6-USPC package dimensions against PCB footprint specifications.

Supervisors Selection Notes

Select this component when a fixed 3.3V threshold is required for voltage supervision. Consider the 200ms delay time for appropriate reset timing relative to system startup. Evaluate the open-drain output compatibility with downstream logic levels. Compare current consumption figures against other LDO or supervisor options if battery life is critical. Ensure the input voltage range covers the maximum expected supply rail.
