MAX6361LUT29+T

Overview

The MAX6361LUT29+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.7 V to 5.5 V and features a fixed threshold voltage of 2.93 V for monitoring power rails. The device provides an active-low, push-pull/totem-pole output with a minimum reset timeout of 150 ms. It supports manual reset functionality and includes a battery backup switch for seamless transition between power sources. The component is housed in a compact SOT-23-6 package and is rated for operation across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides reliable system reset generation with a fixed 2.93 V threshold voltage for precise power monitoring.
• Features a push-pull or totem-pole output configuration that eliminates the need for external pull-up resistors.
• Includes a dedicated battery backup switch to maintain data integrity during power transitions.
• Supports manual reset input for initiating system resets on demand.

Applications

• Microprocessor and microcontroller power supply supervision
• Portable electronic devices requiring low standby current
• Battery-operated systems with backup power switching needs

Procurement Notes

Verify the specific suffix 'LUT29' to confirm the 2.93 V threshold and push-pull output characteristics, as other suffixes in the MAX6361 family may offer different voltages or open-drain outputs. Confirm RoHS compliance status and check for end-of-life notices, as availability may be limited. Ensure the SOT-23-6 footprint matches your PCB design constraints before procurement.

Selection Notes

Select this component when a fixed 2.93 V threshold is required for standard logic families. The push-pull output simplifies board layout by removing external components. Consider the 15 uA typical supply current for battery life optimization. Verify that the 150 ms reset timeout meets the startup requirements of the target processor. The SOT-23-6 package offers a small form factor suitable for space-constrained designs.

Part Context

The MAX6361 series consists of low-power microprocessor supervisors designed for portable applications. This specific variant belongs to the MAX6361LUT sub-family, characterized by its fixed threshold voltage and push-pull output stage. It is part of Maxim Integrated's portfolio of power management solutions, now under Analog Devices, focusing on reliability and low power consumption for embedded systems.

Replacement Considerations

Direct pin-to-pin replacements within the MAX6361 family include variants with different thresholds such as MAX6361LUT28 (2.63 V) or MAX6361LUT30 (3.08 V), provided the voltage level is acceptable. Other Maxim supervisors like the MAX6365 series offer similar functionality but may differ in package type or additional features like chip-enable gating.
