TPS3705-30D

illustrate

In the TPS3705, the TPS3707 microprocessor provides circuit initialization and timing supervision for the supply voltage supervisor family, primarily for DSP and processor systems.

Reset at power-on\assert when the supply voltage is supplied_VDD becomes 1.1 to five, after which the supply voltage monitor monitors_VDD and keep reset\active as long as the voltage V₊for_VDD's_informationStill below the threshold. The output delayed by the internal timer returns to an inactive state (high) to ensure that the system is reset properly. Delay time t = 200 milliseconds_dtyp，After startup_targetV DD₊The threshold voltage has risen beyond the threshold_Vway. When the power supply_voltageDrops below the threshold voltage_Vway, the output becomes valid (low). No external components are required.
