Description
General part information
TPS3103 Series
The TPS310x and TPS311x families of supervisory circuits provide circuit initialization and timing supervision, primarily for DSP and processor-based systems.
During power-on,RESETis asserted low when the supply voltage (VDD) becomes higher than 0.4 V. Thereafter, the supervisory circuit monitors VDDand keeps theRESEToutput low as long as VDDremains below the threshold voltage (VIT–). To ensure proper system reset, after VDDsurpasses the threshold voltage, an internal timer delays the transition of theRESETsignal from low to high for the specified time. When VDDdrops below VIT–, the output transitions low again.
All the devices of this family have a fixed-sense threshold voltage (VIT–) set by an internal voltage divider.
