MAX6364LUT31-T

Overview

The MAX6364LUT31-T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.0 V to 5.5 V and features a fixed reset threshold voltage of 3.1 V. The device provides an active-low, push-pull output with a typical reset delay time of 280 ms. It includes a battery backup switch for seamless power transition monitoring. The component is housed in a compact SOT-23-6 package and supports manual reset functionality. It is designed for operation across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates a battery backup switch to monitor power source transitions between main supply and backup sources.
• Provides a manual reset input allowing external triggering of the reset signal independent of voltage conditions.
• Features an active-low, push-pull output driver capable of directly interfacing with microprocessor reset pins.

Applications

• Microprocessor system power supervision
• Battery-powered portable devices requiring backup power monitoring
• Industrial control systems operating in harsh environments

Procurement Notes

Verify the exact suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the specific threshold voltage corresponds to the '31' designation (3.1 V) as variants exist within the series. Check current availability status as this part may be subject to limited supply or discontinuation notices from the manufacturer. Ensure compatibility with the target PCB footprint for the SOT-23-6 package.

Selection Notes

Select this component when a fixed 3.1 V threshold is required for voltage monitoring. Choose the manual reset variant if external reset control is necessary for the design. Consider the SOT-23-6 package size constraints and the need for a push-pull output stage. Verify that the 280 ms reset delay meets the timing requirements of the connected microprocessor during power-up sequences.

Part Context

This part belongs to the MAX636x family of low-power microprocessor supervisors. These circuits are designed to provide reliable reset signals for digital systems. The MAX6364 specifically adds manual reset capability and battery backup monitoring compared to basic supervisor models. The family is widely used in embedded systems where power integrity is critical.

FAQ

Does the MAX6364LUT31-T include a watchdog timer?

No, the MAX6364LUT31-T does not include a built-in watchdog timer; it functions solely as a voltage supervisor with manual reset and battery backup capabilities.

What is the output configuration of this supervisory circuit?

The device features an active-low, push-pull output, which allows it to drive the reset line of a microprocessor directly without requiring external pull-up resistors.
