Functional Features

Voltage Monitoring

The LTC2900-1IDD#TRPBF continuously monitors the power supply voltage. It compares the voltage level with a programmable threshold and generates a reset signal if the voltage falls below the threshold.

Reset Signal Generation

When the power supply voltage drops below the set threshold, the LTC2900-1IDD#TRPBF asserts the RESET pin, indicating that a system reset is required. This ensures proper operation and prevents data corruption or malfunction.

Adjustable Threshold and Timeout

The threshold and timeout periods of the LTC2900-1IDD#TRPBF can be adjusted according to the specific requirements of the electronic system. This flexibility allows customization for different voltage levels and response times.

Advantages and Disadvantages

Advantages

• Ensures reliable system operation by monitoring power supply voltages
• Provides reset signals to prevent data corruption or malfunction
• Adjustable threshold and timeout for customization
• Compact DFN package for easy integration

Disadvantages

• Requires additional external components for complete functionality
• Limited to monitoring power supply voltages only

Working Principles

The LTC2900-1IDD#TRPBF operates by continuously monitoring the power supply voltage using an internal voltage reference. When the voltage falls below the set threshold, it triggers the generation of a reset signal. The timeout period determines how long the reset signal remains active before deasserting.
