MAX6365PKA44+T

Overview

The MAX6365PKA44+T is a low-power 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 4.38 V for monitoring single-input power rails. The device provides an active-low, open-drain reset output with a typical reset delay time of 280 ms. It includes manual reset functionality and battery backup switching capabilities. The component supports chip-enable gating and consumes only 15 uA of quiescent current. It is housed in an SOT-23-8 surface-mount package and is rated for operation between -40°C and +85°C.

Feature Summary

• Integrates battery backup switching to maintain system integrity during main power loss.
• Supports chip-enable gating for flexible power management control.
• Provides manual reset input capability for user-initiated system resets.

Applications

• Monitoring critical voltage rails in embedded systems
• Battery-powered portable devices requiring low standby current
• Industrial control systems needing reliable power supervision

Procurement Notes

Verify the exact suffix and manufacturer documentation before procurement, as this component may be discontinued or subject to limited availability. Confirm RoHS compliance status and specific lot traceability requirements with authorized distributors. Ensure that the SOT-23-8 footprint matches your PCB design constraints. Check for any obsolescence notices from Analog Devices regarding this specific part number to avoid supply chain disruptions.

Selection Notes

Select this component when a fixed 4.38 V threshold is required for single-supervision applications. It is suitable for designs prioritizing low quiescent current and manual reset flexibility. Consider alternative parts if adjustable thresholds or push-pull outputs are necessary instead of open-drain configurations.
