Functional Features

Voltage Monitoring

The LTC2900-2IDD#TRPBF monitors the voltage levels of two power supply channels simultaneously. It compares the input voltages with the user-defined thresholds and generates a reset signal when the voltage falls below the threshold.

Reset Generation

When the monitored voltage drops below the set threshold, the LTC2900-2IDD#TRPBF asserts the RESET pin, indicating a power failure or an out-of-range condition. This signal can be used to trigger system resets or initiate appropriate actions.

Threshold Adjustment

The TH1 and TH2 pins allow users to adjust the voltage thresholds for each monitoring channel independently. This flexibility enables customization according to specific application requirements.

Advantages and Disadvantages

Advantages

• Accurate voltage monitoring ensures reliable system operation.
• Adjustable thresholds provide flexibility in different applications.
• Low power consumption makes it suitable for battery-powered devices.
• Wide operating temperature range allows usage in various environments.
• Small form factor package enables easy integration into circuit boards.

Disadvantages

• Limited to monitoring two power supply channels.
• Requires external components for complete power management solutions.

Working Principles

The LTC2900-2IDD#TRPBF operates based on a voltage comparator circuit. It continuously compares the input voltages with the user-defined thresholds set through the TH1 and TH2 pins. When the voltage drops below the threshold, the comparator triggers the reset generation circuitry, asserting the RESET pin.
