MAX6866UK46D3S+T

Supervisors Overview

The MAX6866UK46D3S+T is a single-input voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range up to 5.5 V and features a threshold voltage of 4.625 V with an overvoltage threshold of 4.741 V. The device provides an active low, open-drain output and includes manual reset functionality alongside a watchdog timer. It exhibits a reset delay time of 225 ms and consumes a working power current of 7 uA. The component is housed in a SOT-23-5 package suitable for surface mount installation and functions reliably across a temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Integrates manual reset input capability for system control
• Includes built-in watchdog timer for fault monitoring
• Provides active low open-drain output signal

Supervisors Applications

• Microprocessor system supervision

Supervisors Procurement Notes

Verify availability status directly with authorized distributors as supply may be restricted or limited. Confirm RoHS compliance details through official documentation before integration. Ensure ordering suffix matches required specifications. Check regional sales restrictions applicable to your location. Validate datasheet revisions against current production versions.

Supervisors Selection Notes

Choose this component when a single-channel supervisor with open-drain output is required. Select based on the specific 4.625 V threshold requirement for the monitored rail. Consider the 7 uA quiescent current for battery efficiency needs. Verify compatibility with SOT-23-5 footprint constraints. Ensure manual reset and watchdog features align with system design requirements.
