description  
The TPS3801 family of supervisory circuits provide circuit initialization and timing supervision, primarily for  
DSPs and processor-based systems.  
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 active as long as V remains below the threshold voltage  
DD  
DD  
V . An internal timer delays the return of the output to the inactive state (high) to ensure proper system reset.  
IT  
The delay time, t  
= 200 ms, starts after V has risen above the threshold voltage V . When the supply  
d(typ)  
DD IT  
voltage drops below the threshold voltage V , the output becomes active (low) again. No external components  
IT  
are required. All the devices of this family have a fixed sense-threshold voltage V set by an internal voltage  
IT  
divider.  
The TPS3801 devices incorporate a manual reset input, MR. A low level at MR causes RESET to become  
active.  
The product spectrum is designed for supply voltages of 2.5 V, 3 V, 3.3 V, and 5 V. The circuits are available  
in a 5-pin SC-70 (SOT-323) package which is only about half the size of a 5-pin SOT-23 package.  
The TPS3801 devices are characterized for operation over a temperature range of –40°C to 85°C.
