Power Supply Controllers, Monitors datasheet and documents for NJM2103D

NJM2103D

Power Supply Controllers, Monitors Overview

The NJM2103D is a voltage supervisory circuit manufactured by Nisshinbo Micro Devices. It operates within a supply voltage range of 2.5 V to 18 V and features a fixed detection threshold of 4.2 V. The device provides an active-low output signal and consumes a typical operating current of 300 uA. Designed for through-hole installation, it is housed in an 8-DIP package with a maximum power dissipation of 1.3 W. The component supports an extended operating temperature range from -40°C to +125°C.

Power Supply Controllers, Monitors Feature Summary

Provides system reset functionality via active-low output
Monitors single input channel for voltage abnormalities
Supports high-temperature operation up to 125°C

Power Supply Controllers, Monitors Applications

System reset circuits for embedded devices
Voltage monitoring in industrial equipment
Power management supervision in consumer electronics

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix 'D' against official datasheets to confirm the through-hole DIP-8 package configuration. Ensure compatibility with existing PCB footprints designed for 8-DIP components. Confirm that the 4.2 V threshold aligns with target system requirements. Check for end-of-life status or recommended new designations before finalizing procurement plans.

Power Supply Controllers, Monitors Selection Notes

Select this component when a through-hole solution is required for voltage supervision. The 4.2 V threshold suits systems operating near standard 5 V rails. Consider the 300 uA quiescent current for low-power applications. Verify that the 18 V maximum rating exceeds the peak supply voltage. Evaluate thermal performance within the specified -40°C to +125°C range.

Power Supply Controllers, Monitors Part Context

This part belongs to the NJU/NJM2103 series of voltage detectors. It complements surface-mount variants like the NJM2103M and NJU2103AM-TE1. The series offers various packages including DMP-8 and DIP-8. These devices are categorized under PMIC supervisory circuits for reliable power management.
