MAX6855UK33D3+T

Supervisors Overview

The MAX6855UK33D3+T is a single-channel voltage 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 threshold voltage of 3.3 V. The device provides an active low, push-pull output with a manual reset input capability. It includes a reset delay time of 225 ms and consumes a typical operating supply current of 7 uA. The component is housed in a SOT-23-5 surface-mount package and functions across a temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage supervision for single power rails with a fixed 3.3 V threshold.
• Features a manual reset input allowing external control over system reset states.
• Delivers an active low push-pull output signal for direct interface with digital logic.

Supervisors Applications

• Monitoring main power supplies in embedded systems
• Ensuring stable operation in portable electronic devices
• Providing power management supervision in industrial control equipment

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm that the specific suffix indicates the correct threshold voltage and package variant. Check for RoHS compliance documentation if required for regulatory standards. Ensure storage conditions adhere to moisture sensitivity level guidelines to prevent damage prior to assembly.

Supervisors Selection Notes

Select this part when a fixed 3.3 V supervision threshold is required without programmable adjustment. The manual reset feature suits designs needing external intervention for system recovery. Consider the 7 uA quiescent current for battery-sensitive applications. Verify that the SOT-23-5 footprint aligns with existing PCB layout constraints and thermal requirements.
