MAX6348UR33-T

Overview

The MAX6348UR33-T is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. 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 reset delay time of 280 ms and a typical operating supply current of 500 nA. The threshold voltage is specified at 3.3 V, with an overvoltage threshold of 3.958 V. Accuracy is rated at 1.5%. The component functions in temperatures from -40 C to +85 C and is housed in an SC-70-3 package.

Feature Summary

• Ultra-low power consumption with 500 nA supply current
• Active low open-drain reset output
• Factory-set reset threshold voltages
• Compact SC-70-3 surface mount packaging

Applications

• Portable battery-powered equipment
• Consumer electronics
• Industrial control systems
• Communications equipment

Procurement Notes

Verify the exact suffix against official manufacturer documentation to confirm tape-and-reel specifications and availability status. Confirm RoHS compliance details through the datasheet. Ensure the SC-70-3 footprint matches your PCB design requirements before procurement.

Selection Notes

Select this component for applications requiring minimal quiescent current and a compact form factor. The fixed 3.3 V threshold suits standard logic level monitoring. Consider the 280 ms timeout duration relative to system startup requirements. Verify that the open-drain output aligns with downstream interface pull-up configurations.

Part Context

This part belongs to the MAX6348 series of microprocessor reset circuits designed for low-voltage, low-power applications. The series offers various factory-set thresholds to accommodate different supply rails without external resistors. It provides reliable supervision for digital systems requiring simple voltage monitoring solutions.

Replacement Considerations

Check for ADM6348 variants which share similar electrical characteristics and pinouts. Verify package compatibility and threshold voltage alignment when considering cross-brand alternatives.
