Description

General part information

TPS3813-Q1 Series

The TPS3813-Q1 supervisory circuits provide circuit initialization and timing supervision, primarily for DSPs and processor-based systems.

During power on, theRESETpin is asserted when the supply voltage (VDD) becomes higher than 1.1 V. Thereafter, the supervisory circuit monitors VDDand keeps theRESETpin active as long as VDDremains below the threshold voltage (VIT).

An internal timer delays the return of the output to the inactive (high) state to ensure proper system reset. The delay time, td= 25 ms typical, begins after VDDhas risen above the threshold voltage (VIT). When the supply voltage drops below the threshold voltage (VIT), the output becomes active (low) again. No external components are required. All the devices of this family have a fixed-sense threshold voltage (VIT) set by an internal voltage divider.
