MAX6362PUT23+

Overview

The MAX6362PUT23+ is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.63 V to 5.5 V and features a fixed threshold voltage of 2.32 V for monitoring power rails. The device provides an active-low, open-drain reset output with a typical reset delay time of 280 ms. It includes a battery backup pin to maintain supervision during power transitions and supports manual reset functionality via an external push-button switch. The component is housed in a compact SOT-23-6 surface-mount package and is rated for operation across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides reliable system reset generation when monitored supply voltage drops below the specified threshold
• Includes a dedicated battery backup pin to ensure continuous supervision during power source switching events
• Supports manual reset activation through an external push-button switch interface

Applications

• Microprocessor and microcontroller power supply monitoring
• Battery-powered embedded systems requiring low quiescent current
• Industrial control units operating in harsh thermal environments

Procurement Notes

Verify the exact suffix 'PUT23' against official manufacturer documentation to confirm the specific threshold voltage and package variant. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the selected component matches the required electrical specifications for your design before procurement.

Selection Notes

Select this component when a fixed 2.32 V threshold is required for low-voltage digital logic monitoring. Consider the SOT-23-6 package for space-constrained PCB layouts. Evaluate the 15 uA quiescent current against system power budgets. Verify that the open-drain output configuration aligns with the downstream logic input requirements.

Part Context

This part belongs to the MAX636x series of low-power supervisors designed for portable and battery-operated applications. The series offers various threshold voltages and package options to suit different system architectures. The MAX6362 variant specifically integrates manual reset capability alongside standard voltage monitoring functions.

Replacement Considerations

Check for direct cross-references within the MAX636x family offering identical thresholds. Verify compatibility of alternative suppliers' parts regarding pinout, package dimensions, and electrical characteristics such as reset delay and quiescent current.
