The TPS3836, TPS3837, TPS3838 families of  
GND  
supervisory circuits provide circuit initialization  
and timing supervision, primarily for DSP and  
processor-based systems.

RESET  
MR  
During power on, RESET is asserted when the supply voltage V  
becomes higher than 1.1 V. Thereafter, the  
DD  
supervisory circuit monitors V and keeps RESET output active as long as V  
remains below the threshold

reset. The delay time starts after V  
has risen above the threshold voltage V .

When CT is connected to GND a fixed delay time of typical 10 ms is asserted. When connected to V  
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.
