MC34064DM-5R2

Supervisors Overview

The MC34064DM-5R2 is a voltage supervisory circuit manufactured by onsemi, designed for monitoring single-channel input voltages. It operates within a supply voltage range of 1 V to 6.5 V and features an open collector/drain output type. The device provides undervoltage sensing with a threshold of 4.61 V and overvoltage detection at 4.7 V. It consumes 390 uA of operating current and dissipates up to 625 mW of power. The component is housed in an 8-MSOP package, suitable for surface mount installation, and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides undervoltage and overvoltage supervision for a single monitored input channel
• Features an open collector or open drain output configuration
• Operates with low quiescent current consumption of 390 uA
• Supports surface mount installation in compact 8-MSOP packaging

Supervisors Applications

• Monitoring power supply rails in embedded systems
• Voltage supervision in portable electronic devices
• System reset generation in microcontroller-based circuits

Supervisors Procurement Notes

Verify the specific suffix R2 indicates tape and reel packaging when sourcing. Confirm RoHS compliance status as documentation may vary by production batch. Ensure the 8-MSOP footprint matches the target PCB design. Check for obsolescence notices as this part number may be discontinued or replaced by newer revisions in the MC34064 family.

Supervisors Selection Notes

Select this component for applications requiring precise voltage monitoring with minimal power draw. The fixed thresholds simplify design compared to adjustable supervisors. Consider the MSOP package size constraints against available board space. Verify that the open-drain output interface is compatible with the downstream logic levels of the system being monitored.

Supervisors Part Context

This device belongs to the MC34064 series of supervisory circuits from onsemi. It shares functional similarities with other parts in the family but differs in package type and specific threshold settings. The DM suffix typically denotes the MSOP package variant, distinguishing it from SOIC or DIP versions found in the broader product line.

Supervisors Replacement Considerations

MC34064D-5G is a documented alternative offering similar voltage supervision in an SOIC-8 package.
