MAX6364PUT29+T

Overview

The MAX6364PUT29+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.7 V to 5.5 V and features a fixed reset threshold voltage of 2.93 V. The device provides an active-low, open-drain output with a typical reset delay time of 280 ms. It includes a battery backup switch for seamless power transition monitoring and lacks manual reset or watchdog timer capabilities. The component is housed in an SOT-23-6 package and supports surface-mount installation.

Feature Summary

• Integrates a battery backup switch to monitor transitions between main and backup power sources
• Provides a dedicated chip enable input for controlling device operation state
• Features an active-low open-drain reset output compatible with standard logic interfaces

Applications

• Monitoring voltage levels in portable electronic devices
• Supervising power rails in embedded microprocessor systems
• Ensuring system stability during power-up and power-down sequences

Procurement Notes

Verify the specific suffix 'PUT29' confirms the 2.93 V threshold and SOT-23-6 package configuration. Confirm RoHS compliance status through official documentation. Check current availability as distribution may be limited. Ensure the ordering part number matches the exact functional requirements including the chip enable feature.

Selection Notes

Select this component when a fixed 2.93 V threshold is required for single-input voltage supervision. The inclusion of a chip enable pin allows for power-saving control. Verify that the open-drain output type suits the system's pull-up requirements. Consider the 15 uA operating current for low-power design constraints.

Part Context

This part belongs to the MAX6364P series of low-power MPU supervisors. It shares the family's core architecture but differs in threshold voltage and package options. The 'PUT' designation indicates the SOT-23-6 package and specific threshold variant. It complements other MAX636x parts offering different thresholds or additional features like watchdog timers.

Replacement Considerations

Direct substitutes include MAX6364PUT29+ without the tape-and-reel suffix if tube packaging is acceptable. Other MAX6364 variants with different thresholds require circuit redesign. Cross-reference with MAX6363PUT29+ only if chip enable functionality is not required.
