MC33464H-27AT1

Supervisors Overview

The MC33464H-27AT1 is a voltage supervisor from onsemi featuring an extremely low standby current of 0.8 µA at Vin= 1.5 V. It supports a wide input voltage range from 0.7 V to 10 V and monitors power supply voltages from 1.1 V to 5.0 V. The device offers high accuracy with a detector threshold of ±2.5%. It provides two reset output types, including open drain or complementary drive, and is available in surface mount packages such as SOT–89 or SOT–23 5–Pin.

Supervisors Feature Summary

• Extremely low standby current consumption for battery-powered applications
• Wide input voltage operating range supporting diverse power sources
• High accuracy voltage detection threshold ensuring reliable monitoring
• Flexible reset output configurations with open drain or complementary drive options

Supervisors Applications

• Portable electronic devices requiring extended battery life

• Embedded circuits with strict standby current limitations

Supervisors Procurement Notes

Verify the specific suffix 'H-27AT1' against official onsemi documentation to confirm package type and tape/reel specifications. Ensure compatibility with your board design regarding the SOT-23 or SOT-89 footprint. Confirm that the ±2.5% threshold accuracy meets your system's voltage monitoring requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when ultra-low quiescent current is critical for system efficiency. The wide input range allows flexibility in power supply design. Consider the reset output configuration needs; choose between open drain or complementary drive based on downstream logic interface requirements. Verify thermal performance within the chosen surface mount package for your application environment.

Supervisors Part Context

This part belongs to the MC3346x series of voltage supervisors designed for general-purpose monitoring. It complements other onsemi power management solutions by providing reliable reset signals with minimal power overhead. The series supports various threshold voltages to accommodate different logic families and power rails commonly found in consumer and industrial electronics.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the MC3346x family. Verify if other manufacturers offer equivalent low-current supervisors with similar threshold accuracies. Ensure any substitute maintains the required input voltage range and reset output drive capability.
