Ultralow Power, Supply Voltage Supervisor

Check for Samples: TPS3831, TPS3839

FEATURES

DESCRIPTION

The TPS3831 and TPS3839 (both referred to as the

•

Ultralow Supply Current: 150 nA (typ)

Operating Supply Voltage: 0.6 V to 6.5 V

Valid Reset for V_DD> 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 V_DDsupply voltage drops below

the factory-trimmed reset threshold voltage. The reset

output remains asserted for 200 ms (typical) after the

V_DDvoltage rises above the threshold voltage. These

devices are designed to ignore fast transients on the

V_DDpin. Note that the TPS3831 includes a manual

reset input.

Push-Pull RESET Output

Factory-Trimmed Reset Threshold Voltages

Temperature Range: –40°C to +85°C

Packages: 1-mm × 1-mm X2SON or 3-Pin

SOT23

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.
