MAX6364PUT23-T

Overview

The MAX6364PUT23-T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 5.5 V and features a reset timeout of 150 ms minimum. The device utilizes an SOT-23-6 surface-mount package and supports battery backup functionality. It provides an active-low, open-drain output for monitoring a single input channel. The component is rated for operation between -40°C and +85°C ambient temperature.

Feature Summary

• Integrates battery backup switch capability for seamless power transition management
• Provides active-low open-drain reset output signal generation
• Designed for space-constrained applications via compact SOT-23-6 packaging

Applications

• Microprocessor system power supervision
• Battery-powered device voltage monitoring
• Embedded controller reset circuitry

Procurement Notes

Verify the exact suffix designation (+T vs -T) against the manufacturer's current datasheet, as variations may indicate different tape-and-reel specifications or regional compliance markings. Confirm availability status directly with authorized distributors, as this component may be subject to limited supply or end-of-life constraints. Ensure the selected variant matches the required threshold voltage and package type for your specific design implementation.

Selection Notes

Select this component when a low-quiescent current supervisor with integrated battery backup switching is required for single-rail monitoring. The fixed 2.3 V threshold (indicated by the '23' suffix) suits 3.3 V systems with appropriate margin. Verify that the open-drain output interface aligns with the target microprocessor's reset input requirements and that the SOT-23-6 footprint fits the PCB layout constraints.

Part Context

This part belongs to the MAX6364P series of low-power microprocessor supervisors. These devices are engineered to provide reliable reset signals in embedded systems where power integrity is critical. The series typically offers various threshold options and package configurations to accommodate diverse voltage rails and form factor requirements in portable and industrial electronics.

Replacement Considerations

Cross-reference with MAX6364PUT23+T for identical functional specifications. Check MAX6364PUTxx variants for alternative threshold voltages if system rail levels differ. Verify pinout compatibility before substituting with other SOT-23-6 supervisors from the same family.
