RP300K28AA-TR

Supervisors Overview

The RP300K28AA-TR is a supervisory circuit manufactured by Nisshinbo Micro Devices, functioning as a voltage detector with an internal counter-type delay function. It features a threshold voltage of 2.8V and a reset delay time of 200ms. The device operates within a power supply voltage range up to 5.5V and supports manual reset functionality. It utilizes an active low, open drain output type and monitors a single input. The component is housed in a DFN-PLP-1010-4B-4 package suitable for surface mount installation. It maintains an accuracy of 0.8% and operates reliably across a temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates an internal counter-type delay function to prevent false resets during transient voltage fluctuations.
• Provides high monitoring accuracy of 0.8% for precise voltage supervision.
• Features an active low, open drain output configuration for flexible interface compatibility.

Supervisors Applications

• Monitoring battery voltage levels in portable electronic devices
• Supervising power supply rails in embedded systems requiring stable operation
• Providing reset signals for microcontrollers in industrial control equipment

Supervisors Procurement Notes

Verify the specific suffix AA against official Nisshinbo documentation to confirm exact electrical characteristics and packaging details. Ensure the required operating temperature range aligns with the specified -40°C to +85°C limit. Confirm that the DFN-PLP-1010-4B-4 package dimensions fit the target PCB layout constraints before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a fixed 2.8V threshold with a 200ms delay is required for system supervision. Consider the open drain output capability if interfacing with logic levels different from the monitored voltage. Evaluate the thermal performance within the specified operating range to ensure reliability under varying environmental conditions.
