XC6122D434ER-G

Supervisors Overview

The XC6122D434ER-G is a high-precision voltage detector with a watchdog timer, manufactured by Torex Semiconductor. It features an N-channel open-drain output and active-low reset signal. The device monitors a single voltage threshold of 3.4V with a typical release delay time of 100ms. It operates within a supply voltage range of 1.0V to 6.0V and supports a detection voltage range from 1.6V to 5.0V in 100mV increments. The watchdog timeout period is typically 100ms. The component functions across an operating temperature range of -40°C to +85°C and is housed in a compact 6-USP (1.8x2) surface-mount package.

Supervisors Feature Summary

• Integrates a high-precision voltage detector with laser-trimmed thresholds and a built-in watchdog timer for system monitoring.
• Features an EN/ENB pin that allows independent control over the watchdog function while maintaining voltage detection operation.
• Utilizes CMOS process technology to achieve low current consumption without requiring external components for delay circuits.

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 datasheet to confirm the package type and tape & reel configuration. Ensure the part number matches the required 3.4V threshold and 100ms watchdog timeout specifications for your design. Cross-reference the manufacturer's latest documentation to confirm RoHS compliance and environmental classifications before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a precise 3.4V detection threshold is required alongside integrated watchdog functionality. The internal pull-up/pull-down on the EN/ENB pin simplifies circuit design by allowing the pin to remain open during normal watchdog operation. Consider the 6-USP package size for space-constrained applications requiring surface mount assembly.

Supervisors Part Context

This part belongs to the XC6121/XC6122/XC6123/XC6124 series of voltage detectors. The 'XC6122' designation indicates a specific output configuration and feature set within the family. The suffix 'D434' defines the fixed detection voltage at 3.4V, while 'ER-G' specifies the packaging and environmental compliance attributes provided by Torex Semiconductor.

Supervisors Replacement Considerations

Direct substitutes within the same series include XC6122A434ER-G or XC6122C434ER-G, which share identical electrical characteristics and pinouts. Verify that any replacement maintains the 3.4V threshold and 100ms timeout requirements specified for the original application.
