MAX6865UK35D1S+T

Supervisors Overview

The MAX6865UK35D1S+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 up to 5.5 V and features a factory-trimmed reset threshold of 3.5 V. The device utilizes an SOT-23-5 surface-mount package and draws a typical quiescent current of 7 uA. Key functional attributes include an active high push-pull output, manual reset capability, and an integrated watchdog timer. The reset delay time is specified as 15 ms, with an overvoltage threshold of 3.998 V. It supports an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates voltage monitoring, watchdog timer, and manual reset input functions in a compact five-pin package.
• Provides an active high push-pull reset output that asserts when monitored voltage drops below the threshold or upon manual trigger.
• Features low power consumption with a typical quiescent current of 7 uA for battery-operated applications.

Supervisors Applications

• Microprocessor (µP) system supervision
• Battery-powered portable devices
• Consumer electronics requiring power management

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm RoHS compliance and lead-free specifications against current manufacturing records. Validate package integrity and pin configuration prior to integration. Review datasheet revisions for any parameter updates. Ensure storage conditions meet moisture sensitivity level requirements.

Supervisors Selection Notes

Select this component for designs requiring a single-supply supervisor with manual reset and watchdog functionality. Compare threshold voltages and reset delays against system requirements. Consider the SOT-23-5 footprint for space-constrained layouts. Evaluate quiescent current impact on overall system power budget.
