UltraLow Supply-Current/Supply-Voltage Supervisory Circuits  
FEATURES  
DESCRIPTION  
•
Precision Supply Voltage Supervision Range:  
0.9 V, 1.2 V, 1.5 V, 1.6 V, 2 V, and 3.3 V  
The TPS310x and TPS311x families of supervisory  
circuits provide circuit initialization and timing  
supervision, primarily for DSP and processor-based  
systems.  
•
•
•
High Trip-Point Accuracy: 0.75%  
Supply Current of 1.2 µA (typical)  
During power-on, RESET is asserted when the  
supply voltage (VDD) becomes higher than 0.4 V.  
Thereafter, the supervisory circuit monitors VDD and  
keeps the RESET output active as long as VDD  
remains below the threshold voltage (VIT). An internal  
timer delays the return of the output to the inactive  
state to ensure proper system reset. The delay time  
starts after VDD has risen above VIT. When VDD drops  
below VIT, the output becomes active again.  
RESET Defined With Input Voltages as Low as  
0.4 V  
•
Power-On Reset Generator With a Delay Time  
of 130 ms  
•
•
•
Push/Pull or Open-Drain RESET Outputs  
SOT23-6 Package  
Package Temperature Range: –40°C to +85°C  
All the devices of this family have a fixed-sense  
threshold voltage (VIT) set by an internal voltage  
divider.  
APPLICATIONS  
•
Applications Using Low-Power DSPs,  
Microcontrollers, or Microprocessors  
The TPS3103 and TPS3106 have an active-low,  
open-drain RESET output. The TPS3110 has an  
active-low push/pull RESET.

Portable- and Battery-Powered Equipment  
Intelligent Instruments  
Wireless Communication Systems  
Industrial Equipment  
The product spectrum is designed for supply  
voltages of 0.9 V up to 3.3 V. The circuits are  
available in SOT23-6 packages. The TPS31xx family  
is characterized for operation over a temperature  
range of –40°C to +85°C.
