• Provides a manual reset input for immediate system reset.
• Offers a fixed timeout period to ensure proper system initialization.
• Low quiescent current consumption for power-sensitive applications.
• Small form factor package for space-constrained designs.

Advantages

• Reliable voltage monitoring prevents system malfunction due to low or unstable power supply.
• Manual reset input allows for manual intervention in system reset scenarios.
• Fixed timeout period ensures sufficient time for system initialization.
• Wide supply voltage range enables compatibility with various electronic systems.
• Small package size facilitates integration into compact designs.

Disadvantages

• Fixed reset timeout period may not be suitable for all applications requiring longer or shorter timeouts.
• Limited threshold options may restrict compatibility with specific voltage requirements.
• Thin SOT23-6 package may pose challenges during assembly and handling for some users.

Working Principles

The MAX16002BTC+T operates by continuously monitoring the supply voltage using an internal voltage reference. When the voltage falls below the selected threshold, the reset output is asserted, indicating a power failure or unstable voltage condition. The manual reset input allows for immediate system reset when triggered. The fixed timeout period ensures that the reset signal remains active long enough for the system to initialize properly.
