R3114K101A-TR

Supervisors Overview

The R3114K101A-TR is a voltage detector manufactured by Nisshinbo Micro Devices, designed for monitoring single-channel power supply voltages. It operates within a supply voltage range of 0.5 V to 6 V and features a threshold voltage of 1 V. The device offers an accuracy of 0.8% and includes a reset delay time of 40 us. It consumes a working power supply current of 1.4 uA and supports a maximum power dissipation of 400 mW. The component utilizes an open-drain output type without manual reset or watchdog timer functions. It is housed in a DFN-PLP-1010-4 package suitable for surface mount installation.

Supervisors Feature Summary

• Provides precise voltage supervision with 0.8% accuracy for reliable system monitoring.
• Features ultra-low operating current consumption to extend battery life in portable applications.
• Includes backup switch functionality to maintain monitoring during power transitions.

Supervisors Applications

• Monitoring battery voltage levels in portable electronic devices
• Supervising power rails in embedded systems requiring low quiescent current
• Ensuring stable operation in mobile communication equipment

Supervisors Procurement Notes

Verify the specific threshold voltage configuration matches the target application requirements, as the series offers various fixed voltage options. Confirm that the DFN-PLP-1010-4 package dimensions are compatible with the printed circuit board layout and soldering process specifications. Ensure that the open-drain output interface aligns with the input voltage levels of the connected microcontroller or logic gate. Check compliance documentation for RoHS status if required by project regulations.

Supervisors Selection Notes

Select this component when a low-voltage detector with high accuracy and minimal current draw is required. The 1 V threshold is suitable for applications where the monitored rail drops below standard logic levels. Consider the 40 us reset delay to ensure stable signal generation after voltage recovery. Evaluate the thermal performance against the 400 mW power dissipation limit under expected operating conditions.

Supervisors Part Context

This part belongs to the R3114K series of voltage detectors from Nisshinbo Micro Devices. The series is characterized by low power consumption and high precision, making it suitable for battery-operated devices.
