TPS3705-30D

illustrate

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

When the power supply voltage V DD becomes 1.1 to five, the power supply voltage monitor monitors V DD and keeps the reset active as long as the voltage V + V DD information is still below the threshold. The output of the internal timer delay returns to an inactive state (high) to ensure proper system reset. Delay time t = 200 ms dtyp, V after boot DD+ has risen above the threshold voltage V way. When the supply voltage drops below the threshold voltage V, the output becomes valid (low). No external components are required.
