XC6122A342ER-G

Supervisors Overview

The XC6122A342ER-G is a high-precision voltage detector manufactured by Torex Semiconductor using CMOS process technology. It features a fixed detect voltage of 3.4V with a typical hysteresis width of 5% of the detect voltage. The device operates within a supply voltage range of 1.0V to 6.0V and draws a typical static current of 5μA. It includes an integrated watchdog timer with selectable timeout periods ranging from 50ms to 1.6s and release delay times from 3.13ms to 400ms. The output configuration is an N-channel open-drain type, active low. The component is housed in a USP-6C (6-UFDFN) surface-mount package and supports an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

Supervisors Procurement Notes

Verify the specific suffix 'A' indicates the correct package variant and thermal characteristics against the official datasheet. Confirm that the fixed 3.4V threshold aligns with system requirements. Ensure compatibility with the USP-6C footprint during PCB layout. Cross-reference RoHS compliance status with current manufacturer declarations before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 3.4V threshold is required for voltage supervision. Consider the USP-6C package size constraints and the availability of the N-channel open-drain output interface. Evaluate if the integrated watchdog timeout options meet the microprocessor's clock frequency requirements. Verify that the 5μA static current consumption fits within the system's power budget constraints.

Supervisors FAQ

How is the watchdog function controlled?

The watchdog function can be turned ON or OFF by setting the EN/ENB pin to a high or low level, allowing the voltage detector to remain operational while the watchdog is disabled.

What is the output state when a voltage drop is detected?

When the input voltage drops below the detect voltage, the output goes low (VDFL).
