Detailed Pin Configuration

The TCM809RVLB713 has three pins: 1. VDD: Power supply input pin 2. GND: Ground reference pin 3. MR: Manual reset input pin

Functional Features

• Voltage monitoring: The IC continuously monitors the supply voltage and provides a reset signal when it falls below a predefined threshold.
• Manual reset: The MR pin allows for manual resetting of the device, overriding the automatic reset function.
• Active-low reset output: The IC provides an active-low reset signal to the system when the monitored voltage drops below the threshold.

Advantages

• Low power consumption: The IC operates with a low supply current, making it suitable for battery-powered devices.
• Precision voltage threshold options: The availability of multiple voltage threshold options allows for flexibility in different applications.
• Small package size: The compact SOT-23-3 package enables space-saving designs.

Disadvantages

• Limited reset timeout period: The fixed reset timeout period may not be suitable for all applications requiring longer reset delays.
• Single-channel monitoring: The IC can monitor only one voltage channel at a time, limiting its use in systems with multiple power domains.

Working Principles

The TCM809RVLB713 utilizes an internal voltage reference and comparator to continuously compare the supply voltage against the selected threshold. When the voltage drops below the threshold, the reset output is activated, indicating a low-voltage condition. The manual reset input allows for user-initiated resets.
