XC6122D719MR-G

Supervisors Overview

The XC6122D719MR-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 1.9 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 and includes a built-in delay circuit for release timing. The component is housed in a compact SOT-25-5 package and supports an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer function with selectable timeout periods for system monitoring
• Features laser-trimmed internal detection voltage for high accuracy without external components
• Includes an EN/ENB pin to independently control the watchdog function while maintaining voltage detection
• Utilizes low-current CMOS process technology for efficient power management

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 'MR' confirms the SOT-25-5 packaging and tape-and-reel delivery format. Confirm the 'D' code corresponds to the 1.9 V detection threshold as per the official datasheet. Ensure RoHS compliance requirements are met for the target application environment before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a single-input voltage monitor with integrated watchdog functionality is required. The 1.9 V threshold suits applications monitoring standard logic or battery levels. The SOT-25 package offers space efficiency for portable devices. Verify that the 12 µA operating current aligns with the system's power budget constraints.

Supervisors Part Context

This part belongs to the XC6122 series of voltage detectors with watchdog functions. The series employs CMOS technology and laser trimming for precision. The XC6122 variant specifically features an internally pulled-up EN/ENB pin, allowing the watchdog function to be enabled by leaving the pin open. This distinguishes it from other series variants with different control pin configurations.

Supervisors Replacement Considerations

Cross-reference with other XC6122 series parts sharing the same detection voltage (1.9 V) but differing in package type, such as USP-6C variants. Ensure any substitute maintains the N-channel open-drain output configuration and compatible watchdog timeout options.
