MAX6340UK32+T

Overview

The MAX6340UK32+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors system voltages ranging from 1.6V to 5V and asserts a reset signal when the supply voltage falls below its specific threshold. This device features an active-low, open-drain output and utilizes a capacitor-adjustable reset timeout delay for flexible design implementation. It is housed in a compact 5-pin SOT-23 package.

Feature Summary

• Monitors system voltages within the 1.6V to 5V range
• Features externally adjustable reset timeout via external capacitor
• Provides active-low, open-drain reset output

Applications

• Microprocessor supervisor circuits
• Digital system power monitoring
• Battery-powered equipment supervision

Procurement Notes

Verify the exact suffix against official documentation, as variations exist between UK and UKADJ packages. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the selected variant matches the required reset threshold and output configuration for the specific application design.

Selection Notes

Select this component when a low quiescent current solution is required for voltage supervision. The capacitor-adjustable timeout allows customization of reset delays without changing the IC. Consider the SOT-23-5 package size for space-constrained designs requiring reliable power management supervision.

Part Context

This part belongs to the MAX63xx family of CMOS microprocessor supervisory circuits designed by Maxim Integrated. These devices are engineered to monitor power supplies and ensure system stability by asserting reset signals during under-voltage conditions. The family offers various threshold voltages and output configurations to suit different digital system requirements.

FAQ

How is the reset timeout period determined?

The reset timeout period is not fixed internally but is externally set by connecting a capacitor to the appropriate pin, allowing for flexible timing adjustments.

What is the reset output type?

The MAX6340 provides an active-low, open-drain reset output.
