XC6123A732ER-G

Supervisors Overview

The XC6123A732ER-G is a high-precision voltage detector with an integrated watchdog timer manufactured by Torex Semiconductor. It operates within a supply voltage range of 1V to 6V and features a detection threshold of 3.2V. The device utilizes a CMOS process for low current consumption, with a typical operating current of 12µA and standby current of 5µA. It provides an open-drain output and includes a backup function for battery monitoring. The component is housed in a compact 6-USP package with dimensions of 1.8x2mm and supports surface mount installation across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a high-precision voltage detector with a built-in watchdog timer circuit using CMOS technology.
• Features a dedicated enable pin to independently control the watchdog function while maintaining voltage detection.
• Includes a backup switch capability designed for monitoring battery status during power transitions.
• Delivers an active-low reset signal via an open-drain output driver.

Supervisors Applications

• Monitoring system voltages in portable electronic devices
• Battery backup supervision in embedded systems
• Watchdog timing for microcontroller reset protection

Supervisors Procurement Notes

Verify the specific suffix ER-G against official Torex documentation to confirm the 6-USP package type and lead-free compliance. Ensure the 3.2V threshold matches the target application requirements. Confirm RoHS and REACH status through the manufacturer's certificate of conformity before procurement.

Supervisors Selection Notes

Select this component when a combined voltage supervisor and watchdog timer is required in a minimal footprint. The 6-USP package suits space-constrained designs. Verify that the 12µA operating current fits the system's power budget. Ensure the open-drain output interface is compatible with the downstream logic levels.

Supervisors Part Context

This part belongs to the XC6123 series of voltage detectors with watchdog functions. The series offers various threshold voltages and packages. The XC6123A732ER-G specifically denotes the 3.2V threshold variant in the USP-6C package format, distinguishing it from other series members like the XC6121 or XC6122 which may lack the watchdog feature.

Supervisors Replacement Considerations

Official parameter-equivalent substitutes include XC6121A732ER-G, XC6122A732ER-G, and XC6124A732ER-G. These parts share the same threshold voltage and package but may differ in specific functional configurations such as the presence of the watchdog timer or enable pin behavior.
