MC34164P-3RP

Supervisors Overview

The MC34164P-3RP is a micropower undervoltage sensing circuit from onsemi, designed for portable microprocessor-based systems. It operates within a supply voltage range of 1 V to 10 V and features an adjustable reset delay time. The device provides an open collector/drain output and detects undervoltage conditions with a threshold of approximately 2.65 V to 2.75 V depending on the specific variant suffix. It consumes only 32 uA of quiescent current and is housed in a TO-92-3 package suitable for through-hole mounting.

Supervisors Feature Summary

• Micropower operation with low quiescent current consumption
• Undervoltage sensing capability for system reset control
• Adjustable reset delay time functionality
• Open collector/drain output configuration

Supervisors Applications

• Reset controllers in portable microprocessor-based systems
• MPU and logic power supply monitoring in appliance equipment
• Automotive electronic system supervision
• Consumer and industrial equipment power management

Supervisors Procurement Notes

Verify the exact undervoltage threshold value (e.g., 2.65V vs 2.75V) against the official datasheet, as the '3' suffix indicates a specific voltage level within the MC34164 series. Confirm the package type is TO-92-3 and ensure the application supports through-hole mounting. Check RoHS compliance status if required by your manufacturing standards.

Supervisors Selection Notes

Select this component when a low-power, single-channel undervoltage monitor is needed for battery-operated or portable devices. The adjustable reset delay allows customization for different system startup requirements. Ensure the input voltage stays within the 1 V to 10 V operating range and that the open-drain output can interface correctly with the target logic levels.

Supervisors Part Context

The MC34164 series consists of micropower undervoltage sensing circuits intended for use as reset controllers. This family includes various variants with different fixed thresholds and packaging options, such as SOIC-8 and TO-92. The MC34164P-3RP specifically refers to the TO-92-3 through-hole version with a threshold corresponding to the '3' designation.

Supervisors Replacement Considerations

Compatible substitutes include other parts from the MC34164 series with similar voltage thresholds and packages, such as MC34164P-3G or MC34164P-3. Verify pinout compatibility and electrical specifications before substitution.
