Overview
The MAX6429KSUR+T is a low-power voltage supervisor manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1V to 5.5V and features a fixed threshold voltage of 2.9V. The device provides an active-low, push-pull output with a reset delay time of 140ms. It is designed for operation across a temperature range of -40°C to +125°C and is housed in a compact SOT-23-3 package.
Feature Summary
- Provides precise monitoring of system power supply voltages
- Features a factory-trimmed threshold voltage for accurate detection
- Delivers a guaranteed valid logic state down to 1.0V input
Applications
- Battery-powered portable electronic devices
- Microprocessor system supervision
- Embedded controller power management
Procurement Notes
Verify component authenticity through authorized distribution channels due to limited availability status. Confirm that the specific suffix matches the required threshold voltage and package configuration. Ensure compliance with RoHS directives and check for any regional sales restrictions before finalizing procurement orders.
Selection Notes
Select this component when a fixed 2.9V threshold is required for single-supervision applications. Consider the SOT-23-3 footprint for space-constrained designs. Evaluate the 140ms timeout against system startup requirements to ensure proper initialization timing without unnecessary delays during power-up sequences.
Part Context
This part belongs to the MAX6426/MAX6427/MAX6428/MAX6429 family of low-power voltage supervisors. These devices are characterized by ultra-low current consumption and small form factors suitable for battery-operated equipment. The series offers various threshold options and output configurations to support diverse system monitoring needs.
Replacement Considerations
Direct substitutes include other members of the MAX642x family such as the MAX6426, MAX6427, or MAX6428, provided they match the specific threshold voltage and package type requirements.
