• Temperature Range: –40°C to +125°C
• Small SOT23 and 2mm × 2mm QFN Packages
The
TPS3808xxx
family
of
microprocessor
supervisory circuits monitor system voltages from
0.4V to 5.0V, asserting an open-drain RESET signal
when the SENSE voltage drops below a preset
threshold or when the manual reset (MR) pin drops to
a logic low. The RESET output remains low for the
user-adjustable delay time after the SENSE voltage
and manual reset (MR) return above the respective
thresholds.
23
The TPS3808 uses a precision reference to achieve
0.5% threshold accuracy for VIT ≤ 3.3V. The reset
delay time can be set to 20ms by disconnecting the
CT pin, 300ms by connecting the CT pin to VDD using
a resistor, or can be user-adjusted between 1.25ms
and 10s by connecting the CT pin to an external
capacitor. The TPS3808 has a very low typical
quiescent current of 2.4µA so it is well-suited to
battery-powered applications. It is available in a small
SOT23 and an ultra-small 2mm × 2mm QFN
PowerPAD™ package, and is fully specified over a
temperature range of –40°C to +125°C (TJ).

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.

RESET
1
RESET is an open-drain output that is driven to a low impedance state when RESET is asserted (either the
SENSE input is lower than the threshold voltage (VIT) or the MR pin is set to a logic low). RESET will remain
low (asserted) for the reset period after both SENSE is above VIT and MR is set to a logic high. A pull-up
resistor from 10kΩ to 1MΩ should be used on this pin, and allows the reset pin to attain voltages higher than
VDD.

Driving the manual reset pin (MR) low asserts RESET. MR is internally tied to VDD by a 90kΩ pull-up
resistor.

Reset period programming pin. Connecting this pin to VDD through a 40kΩ to 200kΩ resistor or leaving it
open results in fixed delay times (see Electrical Characteristics). Connecting this pin to a ground referenced
capacitor ≥ 100pF gives a user-programmable delay time. See the Selecting the Reset Delay Time section
for more information.

This pin is connected to the voltage to be monitored. If the voltage at this terminal drops below the threshold
voltage VIT, then RESET is asserted.

DEVICE OPERATION
The TPS3808 microprocessor supervisory product
family is designed to assert a RESET signal when
either the SENSE pin voltage drops below VIT or the
manual reset (MR) is driven low. The RESET output
remains asserted for a user-adjustable time after both
the manual reset (MR) and SENSE voltages return
above the respective thresholds. A broad range of
voltage threshold and reset delay time adjustments
are available, allowing these devices to be used in a
wide array of applications. Reset threshold voltages
can be factory-set from 0.82V to 3.3V or from 4.4V to
5.0V, while the TPS3808G01 can be set to any
voltage above 0.405V using an external resistor
divider. Two preset delay times are also
user-selectable: connecting the CT pin to VDD results
in a 300ms reset delay, while leaving the CT pin open
yields a 20ms reset delay. In addition, connecting a
capacitor between CT and GND allows the designer
to select any reset delay period from 1.25ms to 10s.
supply line can be used to allow the reset signal for
the microprocessor to have a voltage higher than VDD
(up to 6.5V). The pull-up resistor should be no
smaller than 10kΩ as a result of the finite impedance
of the RESET line.
SENSE INPUT
The SENSE input provides a terminal at which any
system voltage can be monitored. If the voltage on
this pin drops below VIT, then RESET is asserted.
The comparator has a built-in hysteresis to ensure
smooth RESET assertions and de-assertions. It is
good analog design practice to put a 1nF to 10nF
bypass capacitor on the SENSE input to reduce
sensitivity to transients and layout parasitics.
The TPS3808G01 can be used to monitor any
voltage rail down to 0.405V using the circuit shown in
Figure 11.
VIN
RESET OUTPUT
A typical application of the TPS3808G25 used with
the OMAP1510 processor is shown in Figure 10. The
open-drain RESET output is typically connected to
the RESET input of a microprocessor. A pull-up
resistor must be used to hold this line high when
RESET is not asserted. The RESET output is
undefined for voltage below 0.8V, but this is normally
not a problem since most microprocessors do not
function below this voltage. RESET remains high
(unasserted) as long as SENSE is above its threshold
(VIT) and the manual reset (MR) is logic high. If either
SENSE falls below VIT or MR is driven low, RESET is
asserted, driving the RESET pin to a low impedance.

Once MR is again logic high and SENSE is above VIT

enabled which holds RESET low for a specified reset
delay period. Once the reset delay has expired, the

Figure 11. Using the TPS3808G01 to Monitor a

MANUAL RESET (MR) INPUT
The manual reset (MR) input allows a processor or
other logic circuits to initiate a reset. A logic low
(0.3VDD) on MR causes RESET to assert. After MR
returns to a logic high and SENSE is above its reset
threshold, RESET is de-asserted after the user
defined reset delay expires. Note that MR is internally
tied to VDD using a 90kΩ resistor so this pin can be
left unconnected if MR will not be used.
See Figure 12 for how MR can be used to monitor
multiple system voltages. Note that if the logic signal
driving MR does not go fully to VDD, there will be
some additional current draw into VDD as a result of
the internal pull-up resistor on MR. To minimize
current draw, a logic-level FET can be used as
illustrated in Figure 13.

The capacitor CT should be ≥ 100pF nominal value in
order for the TPS3808xxx to recognize that the

The reset delay time is determined by the time it
takes an on-chip precision 220nA current source to
charge the external capacitor to 1.23V. When a
RESET is asserted the capacitor is discharged. When
the RESET conditions are cleared, the internal
current source is enabled and begins to charge the
external capacitor. When the voltage on this capacitor
reaches 1.23V, RESET is de-asserted. Note that a
low leakage type capacitor such as a ceramic should
be used, and that stray capacitance around this pin
may cause errors in the reset delay time.

The TPS3808 is relatively immune to short negative

Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements,
and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are
sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard
warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where
mandated by government requirements, testing of all parameters of each product is not necessarily performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,
or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a
warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual
property of the third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied
by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional
restrictions.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all
express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not
responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in
such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated
products in automotive applications, TI will not be responsible for any failure to meet such requirements.
