Pin Configuration

The DS1044R-25/T&R IC has the following pin configuration:

1. VCC: Supply voltage input
2. GND: Ground reference
3. RESET: Active-low reset output

Functional Features

• Voltage Monitoring: DS1044R-25/T&R continuously monitors the supply voltage and asserts the reset signal when it drops below the preset threshold.
• Reset Signal Generation: When the supply voltage falls below the threshold, the IC generates an active-low reset signal, which can be used to initialize or restart the system.
• Reset Timeout: The IC includes a timeout feature that ensures the reset signal remains asserted for a specific period after the voltage rises above the threshold. This prevents false resets caused by temporary voltage fluctuations.
