MAX6363PUT23+T

Overview

The MAX6363PUT23+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 fixed threshold voltage of 2.5 V, with additional variants available at 3 V, 3.3 V, and 5 V. The device provides an active-low, open-drain reset output with a typical reset delay time of 280 ms. It consumes only 15 uA of operating current and includes a battery backup switch function. The component is housed in a compact SOT-23-6 package and supports surface-mount installation.

Feature Summary

• Integrates a battery backup switch for seamless power transition management
• Provides active-low open-drain reset signaling for microprocessor control
• Designed for ultra-low power consumption suitable for battery-operated systems

Applications

• Low-power microprocessor system supervision
• Battery-powered portable electronic devices
• Voltage monitoring in handheld instrumentation

Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure correct threshold voltage selection, as the MAX6363 series offers multiple voltage options. Confirm that the open-drain output type aligns with the target circuit design requirements. Check for availability status, as this part may be subject to limited supply or discontinuation notices from the manufacturer.

Selection Notes

Select this component when a dedicated supervisor with integrated battery backup switching is required. Ensure the chosen threshold voltage matches the monitored rail. Verify that the open-drain output interface is compatible with the downstream logic inputs. Consider the SOT-23-6 footprint constraints during PCB layout planning.

Part Context

This part belongs to the MAX6363P series of low-power MPU supervisors. It is distinct from the MAX6363LUT variant which utilizes a push-pull output stage. The MAX6363PUT23+T specifically denotes the 2.5 V threshold version within the open-drain output family.
