MAX6328UR23+TG65

Overview

The MAX6328UR23+TG65 is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 2.3 V. The device utilizes an SOT-23-3 surface-mount package and provides an active low, open-drain output. It includes a reset delay time of 185 ms and maintains high accuracy with a tolerance of 1.5%. Designed for reliability, it functions across an extended temperature range from -40°C to +85°C.

Feature Summary

• Ultra-low-power consumption suitable for battery-operated applications
• Fixed threshold voltage ensures precise power monitoring without external components
• Compact three-pin SOT-23 package minimizes board space requirements

Applications

• Portable electronic devices requiring efficient power management
• Microprocessor system supervision for reliable startup sequences
• Battery-powered equipment needing voltage level monitoring

Procurement Notes

Verify the specific suffix TG65 against official manufacturer documentation to confirm tape-and-reel packaging specifications and lead-free status. Ensure compatibility with existing PCB footprints for the SOT-23-3 package. Cross-reference the exact part number with authorized distributors to confirm current availability and authenticity before procurement.

Selection Notes

Select this component when a fixed 2.3 V threshold is required for single-channel voltage supervision. Consider the 185 ms reset delay and open-drain output characteristics for interface compatibility with downstream logic. Evaluate the ultra-low quiescent current benefits for energy-constrained designs operating within the specified temperature range.
