The TPS3836, TPS3837, TPS3838 families of  
4
RESET  
MR  
supervisory circuits provide circuit initialization  
and timing supervision, primarily for DSP and  
processor-based systems.  
TPS3837  
DBV PACKAGE  
(TOP VIEW)  
During power on, RESET is asserted when the  
supply voltage V  
Thereafter, the supervisory circuit monitors V  
and keeps RESET output active as long as V  
remains below the threshold voltage V . An  
internal timer delays the return of the output to the  
inactive state (high) to ensure proper system  
becomes higher than 1.1 V.

reset. The delay time starts after V  
has risen  
DD  
above the threshold voltage V .  
IT  
When CT is connected to GND a fixed delay time of typical 10 ms is asserted. When connected to V the delay  
DD  
time is typically 200 ms.  
When the supply voltage drops below the threshold voltage V , the output becomes active (low) again.  
IT  
All the devices of this family have a fixed-sense threshold voltage V set by an internal voltage divider.  
IT  
The TPS3836 has an active-low push-pull RESET output. The TPS3837 has active-high push-pull RESET, and  
TPS3838 integrates an active-low open-drain RESET output.
