XC6121C528ER-G

Supervisors Overview

The XC6121C528ER-G is a high-precision voltage detector with watchdog function and ON/OFF control, manufactured by Torex Semiconductor Ltd using CMOS process technology. It features a fixed detect threshold voltage of 2.8V within the 1.6V to 5.0V range. The device operates within a supply voltage range of 1.0V to 6.0V and supports an operating temperature range of -40°C to +85°C. It utilizes a 6-USPC (1.8x2) package with N-channel open-drain output configuration.

Supervisors Feature Summary

• Integrates watchdog timer functionality with selectable timeout periods for system monitoring
• Includes EN/ENB pin for independent control of watchdog function activation
• Utilizes laser trimming technology for precise internal detection voltage settings
• Features built-in delay circuit eliminating requirement 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 against official Torex documentation to confirm package type and environmental compliance status. Ensure the detected voltage code C528 corresponds to the required 2.8V threshold for your application design. Cross-reference the datasheet revision date to confirm current manufacturing status and any potential obsolescence notices before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 2.8V detection threshold is required for voltage monitoring applications. The integrated watchdog function simplifies design by removing external timing components. Consider the N-channel open-drain output compatibility with your microprocessor input logic levels. Verify that the 6-USPC package dimensions fit within your PCB layout constraints.

Supervisors FAQ

How is the watchdog function controlled?

The watchdog function can be turned ON or OFF via the EN/ENB pin. Setting this pin to a specific logic level disables the watchdog while keeping the voltage detector operational.

What is the output configuration of this device?

The XC6121C528ER-G features an N-channel open-drain output configuration, which requires an external pull-up resistor for proper operation.
