RP300K43AC8-TR

Supervisors Overview

The RP300K43AC8-TR is a supervisory circuit manufactured by Nisshinbo Micro Devices, classified as a voltage detector within the PMIC category. It features an internal counter type delay function with 0.8% accuracy. The device operates within a supply voltage range of 720 mV to 5.5 V and draws a working power current of 950 nA. It utilizes a DFN-PLP-1010-4B-4 package and supports manual reset without watchdog or backup switch capabilities. The component ensures reliable monitoring with a maximum power dissipation of 420 mW.

Supervisors Feature Summary

• Integrates an internal counter type delay function for controlled reset timing
• Provides high threshold voltage setting accuracy of 0.8 percent
• Operates with ultra-low standby current consumption suitable for battery applications

Supervisors Applications

• Monitoring power supply voltages in portable electronic devices
• Ensuring system stability in embedded microcontroller circuits
• Providing supervision for low voltage detection in battery-operated equipment

Supervisors Procurement Notes

Verify the specific suffix AC8 corresponds to the required threshold voltage and delay characteristics when sourcing. Confirm that the DFN-PLP-1010-4B-4 package dimensions align with your PCB footprint requirements. Ensure compliance with RoHS directives if applicable to your manufacturing standards. Cross-reference the manufacturer part number against distributor listings to avoid confusion with similar series variants.

Supervisors Selection Notes

Select this component when a precise voltage threshold with a built-in delay function is required. The internal counter mechanism eliminates the need for external timing capacitors, simplifying the design. Consider the 950 nA quiescent current for energy-efficient applications. Verify that the 5.5 V maximum input rating matches the highest expected supply voltage in the target system.

Supervisors Part Context

This part belongs to the RP300K series of voltage detectors from Nisshinbo Micro Devices. The series is designed for supervisory applications requiring accurate monitoring and delayed reset signals. Unlike other variants in the family, this model specifically incorporates an internal counter for delay generation, distinguishing it from simple voltage detectors without timing functions.

Supervisors Replacement Considerations

Direct substitutes include other RP300K series parts with matching delay functions and compatible packages. Verify threshold voltage compatibility before swapping. Alternative manufacturers may offer similar supervisors but require pinout and electrical parameter validation.
