MAX6346XR36-T

Overview

The MAX6346XR36-T is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2V to 5.5V and features a fixed reset threshold voltage of 3.60V. The device provides an active-low, push-pull reset output with a typical reset delay time of 185ms. It consumes ultra-low power, drawing only 500nA of supply current. The component is housed in a compact SOT-23-3 package and is rated for operation across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Fixed factory-set reset threshold voltage ensures precise monitoring
• Active-low push-pull reset output drives digital logic directly
• Compact SOT-23-3 surface-mount packaging minimizes board space

Applications

• Microprocessor (µP) power-supply monitoring
• Battery-powered portable electronics
• Handheld instruments requiring low quiescent current
• Automotive electronic control units

Procurement Notes

Verify the specific suffix 'XR36' confirms the 3.60V threshold variant. Confirm the 'T' indicates tape-and-reel packaging. Ensure the manufacturer designation matches Analog Devices or Maxim Integrated as per the latest corporate structure. Check RoHS compliance status for environmental regulations.

Selection Notes

Select this component when a fixed 3.60V threshold is required for system supervision. Consider the 500nA quiescent current for strict power budget constraints. The SOT-23-3 package is ideal for space-constrained designs. Verify that the 185ms reset delay meets the timing requirements of the monitored microprocessor or memory devices.

Part Context

This part belongs to the MAX6346 series of microprocessor supervisory circuits. The series offers various fixed threshold voltages and timeout delays. The MAX6346 family is designed for low-voltage applications, providing reliable reset signals for digital systems. It complements other Maxim Integrated PMIC solutions for comprehensive power management.

Replacement Considerations

Check for MAX6346 variants with different threshold suffixes if voltage levels differ. Verify pinout compatibility with existing PCB layouts. Ensure thermal performance remains adequate under maximum load conditions.
