MAX6368LKA44+T

Overview

The MAX6368LKA44+T is a low-power 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 an adjustable overvoltage threshold. The device monitors a single input channel and provides an active-low, push-pull output. Key electrical parameters include a reset delay time of 280 ms and a quiescent current of 15 uA. It is housed in an SOT-23-8 package and supports battery backup functionality with chip-enable gating. The component is rated for operation between -40 C and +85 C.

Feature Summary

• Integrates battery backup switching capability to maintain system state during power transitions.
• Includes chip-enable gating logic for controlled supervision activation.
• Delivers active-low push-pull reset signals for direct microprocessor interfacing.

Applications

• Microprocessor power supply monitoring
• Battery-powered embedded systems
• Portable electronic devices requiring low standby current

Procurement Notes

Verify the specific suffix '44' against the manufacturer's official datasheet to confirm the exact adjustable threshold configuration. Confirm RoHS compliance status through the latest documentation. Check availability as the component may be discontinued or subject to limited supply constraints. Ensure the SOT-23-8 footprint matches your PCB design requirements before procurement.

Selection Notes

Select this component when a single-channel supervisor with battery backup and chip-enable features is required. Compare the 15 uA quiescent current against system power budgets. Verify that the 280 ms reset delay meets the target processor's startup timing specifications. Ensure the adjustable overvoltage threshold covers the maximum expected supply voltage.

Part Context

This part belongs to the MAX6368L series of uPower supervisors from Analog Devices/Maxim Integrated. These circuits are designed for applications demanding minimal power consumption while providing reliable voltage monitoring. The series typically offers various threshold options and packaging configurations to suit different board space and performance needs.

Replacement Considerations

Consult the manufacturer's cross-reference guide for verified substitutes. Consider parts from the same MAX6368 family with compatible pinouts and electrical characteristics. Verify that any replacement maintains the SOT-23-8 package and battery backup functionality.
