MAX6368PKA23+

Overview

The MAX6368PKA23+ is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.0 V to 5.5 V and features a fixed reset threshold voltage of 2.32 V with an adjustable overvoltage threshold. The device provides an active high, open-drain output and includes a battery backup switch for seamless power transition. It incorporates a chip enable input for power-down control and offers a reset delay time of 280 ms. The component is housed in an SOT-23-8 package and supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a battery backup switch to manage power transitions between main and backup supplies
• Includes a chip enable input for controlling device operation during low-power states
• Provides an active high open-drain reset output for system supervision

Applications

• Portable electronic devices requiring low standby current
