MAX6865UK33D1S+T

Supervisors Overview

The MAX6865UK33D1S+T is a single-supply power supervisor circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors a single voltage input and provides a reset signal when the supply drops below or exceeds specific thresholds. The device features an active-high, push-pull output driver and supports manual reset functionality via an external input. It operates within a supply voltage range of up to 5.5V and includes a watchdog timer for system reliability. The component is housed in a compact SOT-23-5 surface-mount package and is rated for operation across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage supervision with configurable threshold levels for reliable system monitoring
• Integrates a watchdog timer to detect software malfunctions and trigger automatic resets
• Features an active-high push-pull output for direct interfacing with digital logic circuits
• Supports manual reset input to allow external control over the reset state

Supervisors Applications

• Embedded systems requiring robust power-on reset sequences
• Microcontroller-based designs needing watchdog timer protection
• Portable electronic devices utilizing low-voltage power supplies
• Industrial control units operating in harsh environmental conditions

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to discontinued status. Confirm RoHS compliance and lead-free soldering specifications. Check for alternative sources as original manufacturing may be limited. Ensure compatibility with existing PCB footprints and thermal requirements. Validate datasheet revisions against current design specifications.

Supervisors Selection Notes

Select this part for applications requiring a single-channel supervisor with manual reset capability. Consider the active-high output polarity and push-pull drive strength for interface compatibility. Evaluate the watchdog timeout period against system clock frequencies. Verify that the monitored voltage threshold aligns with the target supply rail. Assess package size constraints relative to available board space.
