MAX6365PKA23+T

Overview

The MAX6365PKA23+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 2.93 V with an overvoltage threshold of 3 V. The device provides an active low, open-drain output and includes manual reset functionality. It incorporates a battery backup switch and chip-enable gating for system control. The reset delay time is specified at 280 ms, and the quiescent current is 15 uA. It is housed in an SOT-23-8 package and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates battery backup switching and chip-enable gating for comprehensive power management
• Provides manual reset capability alongside automatic voltage supervision
• Operates with ultra-low quiescent current suitable for power-sensitive applications

Applications

• Microprocessor power supply monitoring
• Battery-backed system protection
• Portable electronic device power management

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Check for obsolescence notices as this series may be subject to discontinuation. Ensure packaging specifications match design needs, as reel or cut tape options may vary by supplier.

Selection Notes

Select this component when chip-enable gating and battery backup are required simultaneously. Compare against MAX6365LKA variants if push-pull outputs are preferred over open-drain configurations. Verify that the 2.93 V threshold aligns with the monitored rail voltage. Consider the SOT-23-8 footprint compatibility during PCB layout planning.

Part Context

This part belongs to the MAX6365L/P family of low-power supervisors. It shares architectural similarities with other Maxim Integrated voltage monitors but is distinguished by its specific threshold voltage and output drive characteristics. The series is designed for embedded systems requiring reliable reset generation and power sequencing control.
