MAX6365LKA23-T

Overview

The MAX6365LKA23-T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range up to 5.5 V and features a threshold voltage of 2.32 V with an overvoltage threshold of 2.38 V. The device draws a typical operating current of 15 uA and provides a reset delay time of 280 ms. It utilizes an SOT-23-8 package and supports manual reset functionality alongside battery backup switching. The output type is active low push-pull, and it includes chip-enable gating capabilities.

Feature Summary

• Integrates battery backup switching for continuous monitoring during power transitions
• Includes chip-enable gating to control supervisor operation independently
• Supports manual reset input for system initialization control

Applications

• Low-power microprocessor systems requiring voltage supervision
• Battery-operated devices needing backup power monitoring
• Embedded systems utilizing chip-enable gating for power management

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance details and specific lot traceability requirements before procurement. Check for obsolescence notices as the product lifecycle may be restricted. Ensure packaging specifications match design constraints for surface-mount assembly processes.

Selection Notes

Select this component when chip-enable gating and manual reset are required in a compact SOT-23-8 footprint. Compare against MAX6363 variants if chip-enable functionality is unnecessary. Verify that the 2.32 V threshold aligns with the monitored rail voltage. Consider the 15 uA quiescent current for strict power budget applications.

Part Context

This part belongs to the MAX6365L series of low-power uP supervisory ICs. It is distinct from the MAX6363 series by its inclusion of chip-enable gating and manual reset inputs. The 'T' suffix indicates tape and reel packaging. It serves as a voltage supervisor for single-input monitoring applications in portable electronics.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate MAX6365LKA46+T for different threshold requirements or MAX6363LUT23+T if chip-enable gating is not needed.
