Working Principles

The TPS3851H50EDRBR operates by comparing the monitored voltage level with a preset threshold. When the voltage falls below the threshold, the reset output is asserted, indicating a power-on reset condition. The power-on reset delay can be adjusted using an external capacitor connected to the MR pin. The open-drain output allows the device to communicate the reset status to other components in the system.
