XC6122E542ER-G

Supervisors Overview

The XC6122E542ER-G is a high-precision voltage detector with watchdog function and ON/OFF control from the XC6122 series. It features an internally fixed detect voltage of 4.2V, determined by laser trimming technology within the 1.6V to 5.0V range. The device incorporates a built-in delay circuit for release delay time and supports six watchdog timeout period settings ranging from 50ms to 1.6s. It operates on a supply voltage range of 1V to 6V with low current consumption. The output configuration is N-channel open drain, active low when detected. The EN/ENB pin controls the watchdog function state.

Supervisors Feature Summary

• Integrated watchdog timer with configurable timeout periods for system monitoring
• Built-in release delay circuit eliminates need for external components
• ON/OFF control capability via EN/ENB pin for flexible power management
• High-precision detection voltage achieved through internal laser trimming

Supervisors Applications

• Microprocessor watchdog monitoring and reset circuits
• Memory battery backup circuits
• System power-on reset circuits
• Power failure detection

Supervisors Procurement Notes

Verify the specific suffix ER-G against the official Torex Semiconductor datasheet to confirm package type and tape/reel specifications. Ensure the detect voltage code matches the required 4.2V threshold for your application design. Cross-reference the EN/ENB pin internal pull-up/pull-down configuration with your system logic levels to guarantee correct watchdog operation states during initialization.

Supervisors Selection Notes

Select this component when a precise 4.2V detection threshold is required alongside integrated watchdog functionality. Consider the low current consumption characteristics for battery-operated systems. Verify that the N-channel open drain output interface is compatible with the target microprocessor or logic input requirements. Evaluate the available watchdog timeout options to ensure adequate reset timing for the monitored system.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. These ICs utilize CMOS process technology and combine reference voltage sources, delay circuits, comparators, and output drivers in a single package. The series is designed for applications requiring high precision and low power consumption, offering various detect voltages and watchdog configurations.

Supervisors Replacement Considerations

Other parts in the XC6122 series with different detect voltage codes (e.g., XC6122E5xx) may serve as functional substitutes if the voltage threshold differs. Parts from the XC6121, XC6123, or XC6124 series may be compatible depending on package and feature requirements. Always verify electrical parameters and pin compatibility before substitution.
