MAX6346XR35-T

Overview

The MAX6346XR35-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 features a fixed reset threshold of 3.50 V. The device provides an active-low, push-pull reset output with a typical reset delay time of 200 ms. Designed for surface-mount installation, it is housed in a compact SOT-23-3 package. The component supports operation across an industrial temperature range from -40°C to +85°C and consumes a maximum supply current of 500 nA.

Feature Summary

• Monitors power-supply voltages to ensure system reliability
• Provides automatic reset generation upon power-fail events
• Features low-power consumption suitable for battery-operated applications

Applications

• Microprocessor (µP) supervisory circuits
• Battery-powered systems requiring low quiescent current
• Portable electronic devices

Procurement Notes

Verify the specific suffix 'XR35' corresponds to the 3.50 V threshold variant when sourcing. Confirm the 'T' suffix indicates tape-and-reel packaging if reel quantity is required. Ensure the manufacturer designation matches Analog Devices or Maxim Integrated as the part has transitioned between these entities. Check RoHS compliance status for the specific production batch.

Selection Notes

Select this component when a fixed 3.50 V threshold is required for single-channel monitoring. Compare the 200 ms reset delay against system timing requirements. Consider the SOT-23-3 package size constraints. Evaluate the 500 nA supply current against total system power budgets. Verify compatibility with the target operating temperature range of -40°C to +85°C.

Part Context

The MAX6346 series comprises ultra-low-power µP reset circuits designed for monitoring supply voltages. These devices are part of a broader family offering various threshold voltages and timeout delays. The MAX6346 specifically targets applications requiring minimal standby current while maintaining accurate voltage supervision in compact form factors.

Replacement Considerations

Cross-reference other MAX6346 variants with different threshold suffixes (e.g., UR46 for 4.63 V) if voltage levels differ. Verify pinout compatibility with alternative SOT-23-3 supervisors from the same manufacturer.
