MAX6361HUT46

Overview

The MAX6361HUT46 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 up to 5.5 V and features a fixed reset threshold voltage of 4.63 V. The device provides an active high, open-drain output signal with a manual reset input capability. It incorporates a typical reset delay time of 280 ms to ensure stable power-up sequencing. The component is designed for surface-mount installation in a compact SOT-23-6 package. It supports an operating temperature range from -40°C to +85°C and consumes a quiescent current of 15 µA. This supervisor lacks a watchdog timer but includes battery backup functionality for critical data retention during power transitions.

Procurement Notes

Verify the exact suffix UT46 corresponds to the 4.63 V threshold variant when sourcing. Confirm package type matches SOT-23-6 specifications for PCB layout compatibility. Check manufacturer documentation for RoHS compliance status and lead time constraints due to limited availability. Ensure manual reset pin configuration aligns with system design requirements before procurement.

Selection Notes

Select this component when a fixed 4.63 V threshold is required for system supervision. Consider the active high output polarity for interface compatibility with downstream logic circuits. Evaluate the 15 µA quiescent current against total system power budget constraints. Verify that the absence of a watchdog timer meets application safety standards. Confirm thermal performance within the specified -40°C to +85°C operating range.
