TPS3809x 3-Pin Supply Voltage Supervisors
1 Features
3 Description
•
•
•
The TPS3809 family of supervisory circuits provides
circuit initialization and timing supervision, primarily
for DSPs and processor-based systems. The newer
TLV809E device is an alternative with the same pins,
functions and electrical parameters.
•
•
3-pin SOT-23 package
Supply current of 9 μA (typical)
Precision supply voltage monitor
2.5 V, 3 V, 3.3 V, 5 V
Pin-for-pin compatible with MAX 809
Temperature range: –40°C to +85°C
During power-on, RESET is asserted when the supply
voltage VDD becomes higher than 1.1 V. Thereafter,
the supervisory circuit monitors VDD and keeps
RESET active as long as VDD remains below the
threshold voltage VIT. An internal timer delays the
return of the output to the inactive state (high) to
ensure proper system reset. The delay time, td(typ) =
200 ms, starts after VDD has risen above the threshold
voltage VIT. When the supply voltage drops below the
threshold voltage VIT, the output becomes active (low)
again. No external components are required. All the
devices of this family have a fixed sense-threshold
voltage VIT set by an internal voltage divider.

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 3-pin SOT-23. The TPS3809 devices are
characterized for operation over a temperature range
of –40°C to 85°C.

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltage values are with respect to GND. For reliable operation, the device should not be operated at 6.5 V for more than t = 1000h
continuously.

9 Electrostatic Discharge Caution
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled
with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric changes could cause the device not to meet its published
specifications.
