MAX6348XR33+T

Overview

The MAX6348XR33+T is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of up to 5.5 V and monitors a single input channel. The device features an active low, open-drain output type with no manual reset or watchdog timer capabilities. It has a fixed reset delay time of 280 ms and a quiescent supply current of 500 nA. The overvoltage threshold is specified at 3.38 V. The component is housed in a SC-70-3 package and supports surface mount installation. It functions reliably across a temperature range from -40 C to +85 C.

Feature Summary

• Ultra-low power consumption with 500 nA operating current
• Compact SC-70-3 surface-mount packaging for space-constrained designs
• Active low open-drain output configuration

Applications

• Portable battery-powered equipment requiring extended battery life
• Embedded systems needing reliable microprocessor reset signals
• Consumer electronics with limited board space

Procurement Notes

Verify the specific suffix 'XR33' against official datasheets to confirm the 3.3 V threshold variant. Confirm RoHS compliance status through manufacturer documentation. Check current availability as distribution channels may list restricted supply statuses. Ensure the SC-70-3 package matches your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when ultra-low standby current is critical for battery-operated applications. The fixed 280 ms delay suits systems where immediate reset upon brownout is not required. Verify that the 5.5 V maximum supply rating aligns with your system's peak voltage conditions. Consider the open-drain output compatibility with your downstream logic levels.

Part Context

This part belongs to the MAX6348 series of uPower Reset Circuits. These devices are designed for monitoring voltage levels in portable and industrial applications. The series offers various threshold options packaged in small form factors like SC-70 and SOT-23. They provide essential protection for microprocessors and memory devices against undervoltage conditions.

Replacement Considerations

MAX6348UR33+T: Similar functionality but in SOT-23-3 package. ADM6348-33ARTZ-R7: Equivalent performance in SOT-23-3 package.
