RP300K11DA-TR

Supervisors Overview

The RP300K11DA-TR is a supervisory circuit voltage detector manufactured by Nisshinbo Micro Devices. It features a threshold voltage of 1.1 V and operates within a maximum supply voltage of 5.5 V. The device provides an active low, open-drain output with a manual reset function. It incorporates a delay function using an internal counter type mechanism, ensuring stable operation during power transitions. The component is housed in a DFN-PLP-1010-4B-4 package suitable for surface mount technology. It supports a wide operating temperature range from -40°C to +85°C and monitors a single input channel without a watchdog timer or battery backup switch.

Supervisors Feature Summary

• Provides precise voltage monitoring with high accuracy detection capabilities
• Integrates an internal counter-based delay function for reliable reset timing
• Features an active low open-drain output compatible with various logic levels
• Supports manual reset functionality for controlled system recovery

Supervisors Applications

• Portable electronic devices requiring low-voltage supervision
• Battery-powered systems needing accurate power-fail detection
• Embedded controllers requiring stable reset signals during power-up
• Industrial equipment operating in extended temperature environments

Supervisors Procurement Notes

Verify the specific suffix DA against official datasheets to confirm the exact threshold voltage and delay characteristics. Ensure the DFN-PLP-1010-4B-4 package footprint matches your PCB design constraints. Confirm RoHS compliance status through manufacturer documentation before integration. Cross-reference the part number with authorized distributors to avoid counterfeit components. Validate thermal performance requirements against the specified operating temperature range.

Supervisors Selection Notes

Select this component when a fixed 1.1 V threshold is required for system supervision. Consider the internal counter delay feature if external timing components are undesirable. Evaluate the open-drain output compatibility with downstream logic circuits. Assess the package size suitability for space-constrained designs. Verify that the single-input configuration meets the monitoring needs without additional channels.

Supervisors Part Context
