RP300K23DA2-TR

Supervisors Overview

The RP300K23DA2-TR is a supervisory circuit manufactured by Nisshinbo Micro Devices, classified as a voltage detector within the PMIC category. It features a threshold voltage of 2.3 V and supports a single input for monitoring. The device utilizes an active low, open drain output type and includes a manual reset function without a watchdog timer or battery backup switch. It operates with a reset delay time of 200 ms and maintains a supply voltage range from 720 mV to 5.5 V. Accuracy is specified at 0.8%, with a working power current of 950 nA. The component is housed in a DFN-PLP-1010-4B-4 package, suitable for surface mount installation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides high-accuracy voltage detection with 0.8% set accuracy for reliable system supervision.
• Integrates an internal counter-type delay function to prevent false triggering during power transitions.
• Features an active low open drain output compatible with standard CMOS logic interfaces.

Supervisors Applications

• Monitoring battery voltage levels in portable electronic devices

Supervisors Procurement Notes

Verify the specific suffix and package variant against the official datasheet to ensure compatibility with design requirements. Confirm that the active low open drain output aligns with the target logic interface. Check RoHS compliance status and operating temperature range specifications before integration into final assemblies.

Supervisors Selection Notes

Select this component when precise voltage monitoring with minimal quiescent current is required. The internal counter delay function offers protection against transient noise without external components. Ensure the 2.3 V threshold matches the critical voltage level of the monitored circuit. Consider the DFN-PLP-1010-4B-4 package size for PCB layout constraints.

Supervisors Part Context

This part belongs to the RP300K series of voltage detectors designed for general-purpose applications. It distinguishes itself through the inclusion of an internal counter delay mechanism, enhancing stability during power-up and power-down sequences. The series targets cost-sensitive designs requiring reliable supervision with compact packaging solutions.

Supervisors Replacement Considerations

Cross-reference with other RP300K series variants sharing identical threshold voltages and package types. Verify functional equivalence regarding delay mechanisms and output configurations before substitution.
