MAX6348XR35

Overview

The MAX6348XR35+T is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5V and features an active low, open-drain output type. The device monitors one input with a threshold voltage of 3.5V and provides a reset delay time of 280ms. It consumes a working power supply current of 500nA and has an accuracy of 1.5%. The component is housed in an 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 suitable for battery-operated applications
• Compact 3-pin SC-70/SOT-23 package design
• Active low open-drain reset output configuration

Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems needing voltage supervision
• Embedded microprocessor reset circuits

Procurement Notes

Verify the specific suffix (e.g., +T) for packaging details such as reel or cut tape availability. Confirm RoHS compliance status through official manufacturer documentation before integration. Check for obsolescence notices or limited supply alerts directly from Analog Devices distributors. Ensure the selected variant matches the required threshold voltage and package type for your PCB layout.

Selection Notes

Select this component when a single-channel supervisor with ultra-low quiescent current is required. The fixed 3.5V threshold suits 3.3V logic systems. Consider the open-drain output compatibility with your system's pull-up requirements. Verify that the 280ms timeout meets your system's startup timing constraints. Compare against other MAX6348 variants if different thresholds or packages are needed.

Part Context

The MAX6348 series belongs to Maxim Integrated's family of ultra-low-power microprocessor reset circuits. These devices are designed to monitor power-supply voltages and assert a reset signal when voltages fall below specified thresholds. The series offers various threshold options and package styles to accommodate diverse embedded system designs while maintaining minimal power consumption.

Replacement Considerations

Check for direct pin-compatible alternatives within the MAX6348 family with different threshold voltages. Verify functional equivalence with other single-channel supervisors from Analog Devices. Ensure any substitute maintains the same SC-70-3 footprint and electrical characteristics.
