Ultralow Supply Current: 150 nA (typ)  
Operating Supply Voltage: 0.6 V to 6.5 V  
Valid Reset for VDD > 0.6 V  
TPS383x) are ultralow current (150 nA, typical),  
voltage supervisory circuit that monitor a single  
voltage. Both devices assert an active-low reset  
signal whenever the VDD supply voltage drops below  
the factory-trimmed reset threshold voltage. The reset  
output remains asserted for 200 ms (typical) after the  
VDD voltage rises above the threshold voltage. These  
devices are designed to ignore fast transients on the  
VDD pin. Note that the TPS3831 includes a manual  
reset input.

APPLICATIONS  
The ultralow current consumption of 150 nA makes  
these voltage supervisors ideal for use in low-power  
and portable applications. The TPS383x are specified  
to have the correct output logic state for supply  
voltages down to 0.6 V.

The TPS383x feature precision factory-trimmed  
threshold voltages and extremely low-power  
operation. The TPS3831 is available is a 4-pin 1-mm  
× 1-mm (DQN) X2SON package. The TPS3839 is  
available in a 3-pin SOT23 (DBZ) package or a 4-pin  
1-mm × 1-mm (DQN) X2SON package.
