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.
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.

NAME NO.
GND 1 - This pin should be connected to ground with a low-impedance connection.
RESET 2 O
RESET is an active low signal, asserting when VDD is below the threshold voltage. When VDD rises
above VIT, there is a delay time (td) until RESET deasserts.
RESET is a push-pull output stage.
VDD 3 - Supply voltage pin. A 0.1-µF ceramic capacitor from this pin to ground is recommended to improve
stability of the threshold voltage

8 Detailed Description
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.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".

RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6) Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
