Advantages and Disadvantages

Advantages: - Precise voltage monitoring - Adjustable threshold voltage - Low power consumption - Reset timeout feature

Disadvantages: - Limited threshold voltage options - Noisy environments may affect accuracy

Working Principles

The TPS3851H30EDRBR operates by continuously monitoring the supply voltage through the TH pin. When the voltage falls below the selected threshold voltage, the RESET pin is driven low, indicating a reset condition. The reset signal remains active for the specified timeout period, even if the voltage returns to an acceptable level within that time. The MR pin allows for manual reset control, overriding the automatic reset functionality.
