MAX6865UK36D4S+T

Supervisors Overview

The MAX6865UK36D4S+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 1.2 V to 5.5 V and features a fixed threshold voltage of 3.6 V for power monitoring. The device provides an active high, push-pull reset output with a manual reset input capability. It integrates a watchdog timer with a timeout period of 1.8 seconds. The component is housed in a compact SOT-23-5 surface-mount package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer function for system reliability monitoring
• Provides an active high, push-pull reset output signal
• Includes a manual reset input pin for user-initiated control

Supervisors Applications

• Portable equipment requiring low-voltage supervision
• Battery-powered systems needing power management
• Microprocessor-based circuits requiring reset generation

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm RoHS compliance and package integrity upon receipt. Cross-reference datasheet specifications against design requirements before integration. Check for alternative sources if original manufacturing supply is unavailable.

Supervisors Selection Notes

Select this part when a fixed 3.6 V threshold is required for single-supply monitoring. The active high push-pull output suits logic interfaces needing strong drive capability. The integrated watchdog timer eliminates external components for timing supervision. Ensure the SOT-23-5 footprint matches the PCB layout constraints.
