MAX6368PKA31+T

Overview

The MAX6368PKA31+T is a low-power supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in an SOT-23-8 surface-mount package. It features a fixed threshold voltage of 3.08 V and supports a maximum supply voltage of 5.5 V. The device operates with a quiescent current of 15 uA and includes battery backup switching capabilities alongside chip-enable gating. It provides an active high/open drain output with a reset delay time of 280 ms. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates battery backup switching for seamless power transition management
• Includes chip-enable gating functionality for system control
• Provides adjustable overvoltage threshold detection
• Delivers active high or open drain output signals

Applications

• Portable electronic devices requiring low-power monitoring
• Battery-operated systems needing backup power switching
• Embedded controllers requiring voltage supervision

Procurement Notes

Verify component authenticity through authorized distributors due to discontinued status indicators in some regions. Confirm RoHS compliance details via official documentation. Ensure the SOT-23-8 package matches PCB footprint requirements. Validate the 3.08 V threshold specification against design needs. Check regional availability restrictions before finalizing procurement plans.

Selection Notes

Select this part when a fixed 3.08 V threshold is required without manual reset options. Consider the 15 uA operating current for battery-sensitive designs. Verify compatibility with the SOT-23-8 footprint during layout. Ensure the 280 ms reset delay meets system timing constraints. Confirm that chip-enable gating aligns with control logic requirements.

Part Context

This component belongs to the MAX6368H/P series of supervisory circuits designed for low-power applications. It shares family features such as battery backup and chip-enable gating but differs in specific threshold voltages and suffix codes. The PKA31 variant specifically denotes the 3.08 V threshold option within the SOT-23-8 package configuration.
