DESCRIPTION  
The TPS3813 family of supervisory circuits provides circuit initialization and timing supervision, primarily for  
DSPs and processor-based systems.  
During power on, RESET is asserted when supply voltage (VDD) becomes higher than 1.1 V. Thereafter, the  
supervisory circuit monitors VDD and keeps RESET active as long as VDD remains below the threshold voltage  
(VIT). An internal timer delays the return of the output to the inactive state (high) to ensure proper system reset.  
The delay time, td = 25 ms typical, starts after VDD has 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.
