MAX6865UK35D2L+T

Supervisors Overview

The MAX6865UK35D2L+T is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of up to 5.5 V and features a fixed threshold voltage of 3.5 V for power monitoring. The device provides an active high, push-pull output signal and includes manual reset functionality alongside a watchdog timer interface. It supports a minimum reset timeout of 40 ms and maintains low quiescent current consumption of 7 µA. The component is designed for surface mount installation in SOT-23-5 packages and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates manual reset capability with a dedicated input pin for user-initiated system recovery.
• Features a watchdog timer interface allowing external microcontrollers to maintain system stability.
• Delivers an active high push-pull output for direct logic interfacing without additional pull-up requirements.

Supervisors Applications

• Embedded systems requiring reliable power-on reset sequences
• Microcontroller-based designs needing watchdog supervision
• Industrial control units operating in harsh thermal environments

Supervisors Procurement Notes

Verify the specific suffix D2L against official datasheets to confirm the exact threshold and package variant, as suffixes define critical electrical parameters. Confirm availability status as this series may be discontinued or subject to limited supply constraints. Ensure compatibility with existing PCB footprints for SOT-23-5 packages during procurement planning.

Supervisors Selection Notes

Select this component when an active high output is required rather than the more common open-drain configuration. The inclusion of manual reset and watchdog interfaces makes it suitable for complex embedded architectures. Verify that the 3.5 V threshold aligns with the monitored rail's nominal voltage to ensure proper trip points under varying load conditions.

Supervisors Part Context

This part belongs to the MAX6865 family of single-supply voltage supervisors. These devices are engineered to monitor a single voltage rail and generate a reset signal upon detecting out-of-range conditions. The family typically offers various threshold options and output configurations to suit different system requirements.

Supervisors Replacement Considerations

Check for MAX6865 variants with matching 3.5 V thresholds and active high outputs. Ensure substitute parts support the same SOT-23-5 footprint and include manual reset and watchdog features if required by the design.
