MAX6364PUT46+T

Overview

The MAX6364PUT46+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2V to 5.5V and features a fixed reset threshold voltage of 4.63V. The device provides an active-low, push-pull output with a typical reset delay time of 280ms. It consumes only 15µA of quiescent current and includes a battery backup pin for seamless power transition monitoring. The component is housed in a compact SOT-23-6 package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates a dedicated battery backup pin to monitor voltage transitions between primary and secondary power sources.
• Provides a fixed 4.63V reset threshold with high accuracy for reliable system supervision.
• Features an active-low, push-pull output driver capable of directly interfacing with microprocessor reset pins.

Applications

• Microprocessor system power supervision
• Battery backup switching circuits
• Portable electronic devices requiring low standby current

Procurement Notes

Verify the specific suffix 'PUT46' confirms the SOT-23-6 package and 4.63V threshold. Confirm RoHS compliance status through official manufacturer documentation. Ensure the '+T' indicates tape-and-reel packaging if required for assembly. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a fixed 4.63V threshold is required for systems powered between 1.2V and 5.5V. The integrated battery backup feature makes it suitable for applications needing uninterrupted power monitoring during source switchover. Consider the 15µA quiescent current for battery-operated designs where power efficiency is critical.

Part Context

This part belongs to the MAX636x series of low-power microprocessor supervisors. The series offers various threshold voltages and package options to accommodate different system requirements. The MAX6364 variant specifically includes the battery backup functionality, distinguishing it from standard supervisor ICs without this feature.

FAQ

What is the function of the VBAT pin on the MAX6364PUT46+T?

The VBAT pin serves as a battery backup input. It allows the supervisor to monitor the voltage of a secondary power source, ensuring a seamless transition to backup power if the primary supply fails.

Does the MAX6364PUT46+T include a manual reset input?

No, the MAX6364PUT46+T does not include a manual reset (MR) input. Reset generation is automatic based on the monitored supply voltage levels.
