MC33465N-30CTR

Supervisors Overview

The MC33465N-30CTR is a single-channel voltage supervisor integrated circuit manufactured by onsemi. It operates within a supply voltage range of 1.65 V to 5.5 V and functions at a fixed threshold of +3.0 V. The device utilizes CMOS technology and is housed in a compact SOT-23 (PDSO5) package with five pins. It supports an operating temperature range from -40 °C to +85 °C, ensuring reliable performance in standard commercial environments.

Supervisors Feature Summary

• Provides precision voltage monitoring for power supply integrity
• Features a fixed output threshold for consistent supervision
• Utilizes low-power CMOS architecture for efficiency

Supervisors Applications

• Portable electronic devices requiring battery level monitoring
• Embedded systems needing power-on reset generation
• Microcontroller circuit protection against undervoltage conditions

Supervisors Procurement Notes

Verify the specific suffix 'CTR' indicates tape-and-reel packaging when sourcing. Confirm the '+3V' threshold designation matches the target application's voltage requirements. Ensure compatibility with the SOT-23 footprint during PCB layout. Cross-reference the manufacturer part number to distinguish from similar variants like the MC33465N-43CTR which offers a different threshold.

Supervisors Selection Notes

Select this component when a fixed 3.0 V supervision threshold is required for single-channel monitoring. Consider the SOT-23 package size if board space is limited. Evaluate the CMOS input characteristics against the driving source impedance. Verify that the -40 °C to +85 °C temperature range meets the operational environment specifications.

Supervisors Part Context

This part belongs to the MC33465 family of voltage supervisors. Variants within this series differ primarily by their fixed output thresholds, such as the MC33465N-43CTR which monitors at +4.3 V. All members share the same CMOS process and SOT-23 packaging, allowing for design flexibility while maintaining consistent physical integration.

Supervisors Replacement Considerations

The MC33465N-43CTR serves as a functional substitute if the application requires a higher supervision threshold of +4.3 V instead of +3.0 V. Other generic voltage supervisors may replace it only if pinout, package type, and threshold voltage are identical or compatible.
