FEATURES
DESCRIPTION
The TPS3831 and TPS3839 (both referred to as the
2
Ultralow Supply Current: 150 nA (typ)
TPS383x) are ultralow current (150 nA, typical),
Operating Supply Voltage: 0.6 V to 6.5 V
voltage supervisory circuit that monitor a single
Valid Reset for VDD > 0.6 V
voltage. Both devices assert an active-low reset
signal whenever the VDD supply voltage drops below
Push-Pull RESET Output
the factory-trimmed reset threshold voltage. The reset
Factory-Trimmed Reset Threshold Voltages
output remains asserted for 200 ms (typical) after the
Temperature Range: –40°C to +85°C
VDD voltage rises above the threshold voltage. These
devices are designed to ignore fast transients on the
Packages: 1-mm × 1-mm X2SON or 3-Pin
VDD pin. Note that the TPS3831 includes a manual
SOT23
reset input.
APPLICATIONS
The ultralow current consumption of 150 nA makes
these voltage supervisors ideal for use in low-power
Portable and Battery-Powered Equipment
and portable applications. The TPS383x are specified

available in a 3-pin SOT23 (DBZ) package or a 4-pin
1-mm × 1-mm (DQN) X2SON package.
