- VCC: Positive supply voltage
- TH: Threshold voltage selection pin
Functional Features
- Precision voltage monitoring: The MAX6425UK16+G103 accurately monitors the voltage level of a power supply.
- Reset signal generation: When the monitored voltage falls below the set threshold, the IC generates an active-low reset signal.
- Adjustable threshold and timeout: The device allows for flexibility in setting the voltage threshold and timeout period.
- Low-power operation: With a quiescent current of only 1µA, the IC minimizes power consumption.
Advantages and Disadvantages
Advantages: - Accurate voltage monitoring ensures reliable system operation. - Adjustable threshold and timeout provide customization options. - Low-power operation prolongs battery life in portable applications.
Disadvantages: - Limited voltage range of 1.6V to 5.5V may not be suitable for all applications. - SOT23-5 package may require additional space on the PCB compared to smaller packages.
Working Principles
The MAX6425UK16+G103 operates by comparing the input voltage with the threshold voltage set by the TH pin. If the input voltage falls below the threshold, the IC generates an active-low reset signal on the RESET pin. The reset signal remains active until the input voltage rises above the threshold or a timeout period elapses.
Application Field Plans
The MAX6425UK16+G103 finds applications in various fields, including:
- Battery-powered devices: Ensures proper operation and prevents damage due to low voltage conditions.
- Microcontroller systems: Provides a reliable reset signal during power-up and voltage fluctuations.
- Industrial control systems: Monitors power supply integrity and initiates system resets when necessary.
- Automotive electronics: Protects sensitive components from voltage drops and ensures safe operation.
Alternative Models
- MAX6426UK26+T: Similar functionality but with a different package (SOT23-6).
- MAX6427UK29+T: Higher voltage range (up to 9.6V) with adjustable threshold and timeout.
- MAX6428UK22+T: Lower voltage range (down to 0.9V) with fixed threshold and adjustable timeout.
These alternative models offer similar voltage monitoring and reset capabilities, catering to different application requirements.
