MAX6340UK40+T

Overview

The MAX6340UK40+T is a low-power voltage 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 threshold voltage of 4 V with an overvoltage threshold of 4.1 V. The device provides an active low, open drain output and includes a reset timeout delay of 4.375 ms. It consumes only 2.5 uA of operating supply current and functions reliably across a temperature range from -40 C to +125 C. The component is housed in an SOT-23-5 package.

Feature Summary

• Provides voltage supervision with capacitor-adjustable reset timeout delay
• Features active low open drain output for system reset signaling
• Designed for low-power applications with minimal supply current consumption

Applications

• Microprocessor power supply monitoring
• Battery-powered electronic systems
• Embedded controller reset circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices. Ensure the SOT-23-5 package matches design requirements. Validate electrical parameters against official datasheets before integration into production systems.

Selection Notes

Select this component when a low quiescent current supervisor is required for single-input voltage monitoring. The open drain output suits logic interfaces requiring external pull-up resistors. Verify that the 4 V threshold aligns with the target supply rail. Consider the thermal performance within the specified industrial temperature range.
