Overview
The MAX6327UR27+T is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed threshold voltage of 2.7 V. The device provides an active low, open-drain output with a reset delay time of 185 ms. It consumes 500 nA of operating current and functions reliably across a temperature range of -40°C to +85°C. Packaged in a compact SOT-23-3 format, it supports single-input monitoring without manual reset or watchdog timer capabilities.
Feature Summary
- Ultra-low power consumption suitable for battery-operated systems
- Compact three-pin surface-mount packaging for space-constrained designs
- Fixed threshold voltage detection for precise power supervision
Applications
- Portable electronic devices requiring efficient power management
- Microcontroller system reset circuits
- Battery-powered instrumentation
Procurement Notes
Verify component authenticity through authorized distributors. Confirm RoHS compliance status via official documentation. Ensure storage conditions meet manufacturer specifications to maintain reliability. Check for obsolescence notices as availability may be limited. Validate package markings against datasheet standards before integration.
Selection Notes
Select this component when a fixed 2.7 V threshold is required for voltage supervision. Consider the SOT-23-3 package for minimal board space utilization. Evaluate the 500 nA quiescent current against system power budgets. Ensure the active low open-drain output aligns with downstream logic requirements.
Part Context
This part belongs to the MAX6327X series of ultra-low-power voltage detectors. It shares functional similarities with other Maxim Integrated supervisory circuits but offers specific threshold and package options. The series targets applications demanding minimal standby current and reliable power monitoring in compact form factors.
Replacement Considerations
MAX6327UR28+T: Offers a 2.8 V threshold instead of 2.7 V. MAX6327UR29+T: Provides a 2.9 V threshold option. Verify threshold compatibility before substitution.
