MAX6364LUT46-T

Overview

The MAX6364LUT46-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 4.6V. The device provides an active-low, push-pull output with a typical reset delay time of 280ms. It includes a battery backup switch for maintaining system state during power transitions. The component is housed in a compact SOT-23-6 package and supports operation across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates a battery backup switch to preserve critical data during main power loss
• Provides precise voltage monitoring with a fixed 4.6V reset threshold
• Features an active-low, push-pull output driver for direct logic interfacing

Applications

• Portable electronic devices requiring reliable power management
• Battery-operated systems needing backup power supervision
• Embedded controllers requiring automated reset generation

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm the exact threshold voltage matches the design requirement as variants exist within the series. Check current availability status as distribution may be limited or subject to factory special orders. Ensure the operating temperature range aligns with the target application environment.

Selection Notes

Select this component when a fixed 4.6V threshold is required for system supervision. Consider the SOT-23-6 package size for space-constrained designs. Evaluate the 15µA quiescent current against total system power budgets. Verify compatibility with the target microprocessor's reset input requirements.

Part Context

This part belongs to the MAX6363/MAX6364 family of low-power supervisors. These circuits are designed to monitor voltage levels and generate reset signals for microprocessors and memory devices. The family offers various threshold options and packages to suit different application needs while maintaining low power consumption.

Replacement Considerations

Cross-reference with other MAX6364 variants having the same 4.6V threshold but different packages if pinout compatibility allows. Verify functional equivalence with other Maxim integrated supervisor ICs offering similar reset delays and battery backup features.
