Disadvantages

  • Limited voltage supervision range of 2.5V may not be suitable for all applications requiring higher voltage monitoring.

Working Principles

The TPS3824-25DBVRG4 operates by continuously monitoring the supply voltage. If the voltage falls below the preset threshold (2.5V), the reset output is asserted low, indicating an undervoltage condition. The power-on reset circuit ensures that the reset output remains low during power-up, providing a controlled start-up sequence. Additionally, the watchdog timer monitors the system's operation, generating a reset signal if it detects a fault or malfunction.
