Overview
The MAX6347XR38-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors power-supply voltages and asserts a reset output when the supply falls below a factory-set threshold of 3.8V. The device features an active-high, push-pull reset output with a minimum timeout period of 100ms. It operates within a temperature range of -40°C to +85°C and is housed in a SC-70-3 surface-mount package.
Feature Summary
- Monitors power-supply voltage levels against a fixed 3.8V threshold
- Provides an active-high, push-pull reset signal for reliable logic interfacing
- Ensures system stability with a guaranteed minimum 100ms reset timeout delay
Applications
- Microprocessor (µP) supervisory circuits
- Power supply monitoring systems
- Embedded controller reset generation
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm that the 'XR38' designation corresponds to the 3.8V threshold and SC-70-3 package variant. Check current availability status as this component may be subject to limited supply or discontinuation notices from the manufacturer.
Selection Notes
Select this component when an active-high reset signal is required for digital logic compatibility. The fixed 3.8V threshold suits applications where the monitored rail must remain above this level for proper operation. Ensure the SC-70-3 package fits the PCB layout constraints and thermal requirements of the design.
Part Context
This part belongs to the MAX6347 series of low-voltage, low-power µP reset circuits. It is designed to monitor single power supplies and provide a clean reset signal to microprocessors and memory devices during power-up and brown-out conditions, ensuring deterministic system initialization.
Replacement Considerations
Consult official cross-reference data for direct pin-compatible substitutes within the MAX634x family or other Maxim Integrated supervisory circuits with matching active-high outputs and similar threshold voltages.
