XC6118N47DGR-G

Supervisors Overview

The XC6118N47DGR-G is a voltage detector manufactured by Torex Semiconductor Ltd, designed for monitoring single power supply rails. It features an N-channel open-drain output configuration with active-low reset signaling. The device operates within a supply voltage range of 0.8V to 5.0V and offers a detection threshold of 4.7V. It is housed in a compact 4-USP (1.2x1.6mm) surface-mount package with an exposed pad. The component supports a wide operating temperature range from -40°C to +85°C and complies with RoHS standards.

Supervisors Feature Summary

• Separate sense pin allows independent monitoring of power supplies distinct from the IC's own VDD.

Supervisors Applications

• Microprocessor system supervision
• Battery charge voltage monitoring
• Portable equipment power management

Supervisors Procurement Notes

Verify the specific suffix 'N' indicates the N-channel open-drain output variant, as other suffixes denote CMOS push-pull outputs. Confirm the '47' code corresponds to the 4.7V threshold. Ensure the 'G' suffix aligns with current RoHS compliance requirements. Cross-reference the 4-USP package dimensions against PCB footprint specifications before finalizing procurement.

Supervisors Selection Notes

Select this part when a low-active open-drain interface is required for wired-OR logic or level shifting. The separate sense pin is critical if the monitored rail must be tracked even when it drops below the IC's minimum operating voltage. Verify that the 4.7V threshold matches the target system's brown-out protection requirements.

Supervisors Part Context

This component belongs to the XC6118 series of voltage detectors. The series distinguishes between CMOS output types (suffix C) and N-channel open-drain types (suffix N). The XC6118 family provides high accuracy and low standby current, making it suitable for battery-operated devices requiring precise power management.

Supervisors FAQ

Can the XC6118N47DGR-G monitor a voltage lower than its own supply voltage?

Yes, because the sense pin is separated from the power supply pin, the IC can maintain detection state even if the monitored voltage drops to 0V.

What is the function of the N-channel open-drain output?

The N-channel open-drain output requires an external pull-up resistor and allows for flexible interfacing with different logic levels or wired-OR configurations.
