XC6121D528MR-G

Supervisors Overview

The XC6121D528MR-G is a high-precision voltage detector manufactured by Torex Semiconductor Ltd. It operates within a supply voltage range of 1 V to 6 V and features a fixed detection threshold of 2.8 V. The device utilizes CMOS technology for low current consumption, with a typical operating current of 12 µA and standby current of 5 µA. It provides an open-drain output and includes a watchdog timer function. 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 for system reliability monitoring
• Features a dedicated ON/OFF control pin for power management
• Utilizes CMOS process technology for ultra-low current consumption
• Provides open-drain output compatible with various logic levels

Supervisors Applications

• Battery-powered portable electronic devices requiring low quiescent current
• Microprocessor reset circuits in embedded systems
• Voltage supervision for battery backup switching applications
• Watchdog timer implementation in industrial control modules

Supervisors Procurement Notes

Verify the specific suffix 'D' indicates the presence of the watchdog timer function, as this distinguishes it from other variants in the XC6121 series. Confirm the '528' code corresponds to the 2.8 V threshold voltage. Ensure the 'MR-G' designation matches the required SOT-25-5 packaging and RoHS compliance status for your manufacturing process.

Supervisors Selection Notes

Select this component when a fixed 2.8 V threshold is required alongside integrated watchdog functionality. It is suitable for applications demanding minimal standby current below 10 µA. Consider the SOT-25-5 package size constraints and the open-drain output requirement. Verify that the 6 V maximum input voltage aligns with the system's supply rail.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. The XC6121 series specifically focuses on high-precision detection with low current consumption. The 'D' suffix typically denotes the inclusion of a watchdog timer, differentiating it from basic voltage detectors in the same family.

Supervisors FAQ

What is the purpose of the ON/OFF control pin?

The ON/OFF control pin allows external control over the operation of the voltage detector, enabling power saving by shutting down the IC when not in use.

Does the XC6121D528MR-G include a manual reset function?

No, the XC6121D528MR-G does not feature a manual reset pin; reset is triggered automatically based on voltage thresholds or watchdog timeout.
