The LP3470 asserts a reset signal whenever the VCC
supply voltage falls below a reset threshold. The
reset time-out period is adjustable using an external
capacitor. Reset remains asserted for an interval
(programmed by an external capacitor) after VCC has
risen above the threshold voltage.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature),
θJA (junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any
temperature is PDmax = (TJmax − TA)/ θJA or the number given in the Absolute Maximum Ratings, whichever is lower.

Minimum and maximum limits in standard typeface are 100% production tested at 25°C. Minimum and maximum limits in full operating
temperature range are ensured through correlation using Statistical Quality Control (SQC) methods. The limits are used to calculate TI's
Average Outgoing Quality Level (AOQL).
Typical numbers are at 25°C and represent the most likely parametric norm.
VHYST affects the relation between VCC and Reset as shown in the timing diagram.
tRP is programmable by varying the value of the external capacitor (C1) connected to pin SRT. The equation is: tRP = 2000 × C1 (C1 in
µF and tRP in ms).

7 Detailed Description
7.1 Overview
The LP3470 micropower voltage supervisory circuit provides a simple solution to monitor the power supplies in
microprocessor and digital systems and provides a reset controlled by the factory-programmed reset threshold
on the VCC supply voltage pin. When the voltage declines below the reset threshold, the reset signal is asserted
and remains asserted for an interval programmed by an external capacitor after VCC has risen above the
threshold voltage. The reset threshold options are 2.63 V, 2.93 V, 3.08 V, 3.65 V, 4 V, 4.38 V, 4.63 V.

7.3 Feature Description
7.3.1 Reset Time-Out Period
The reset time-out period (tRP) is programmable using an external capacitor (C1) connected to pin SRT of
LP3470. A ceramic chip capacitor rated at or above 10 V is sufficient. The reset time-out period (tRP) can be
calculated using Equation 1.
tRP (ms) = 2000 x C1 (µF)
(1)
For example a C1 of 100 nF will achieve a tRP of 200 ms. If no delay due to tRP is needed in a certain application,
the pin SRT must be left floating.
7.3.2 Reset Output
In applications like microprocessor (µP) systems, errors might occur in system operation during power up, power
down, or brownout conditions. It is imperative to monitor the power supply voltage to prevent these errors from
occurring.
The LP3470 asserts a reset signal whenever the VCC supply voltage is below a threshold (VRTH) voltage. Reset is
ensured to be a logic low for VCC > 0.5 V. Once VCC exceeds the reset threshold, the reset is kept asserted for a
time period (tRP) programmed by an external capacitor (C1); after this interval Reset goes to logic high. If a
brownout condition occurs (monitored voltage falls below the reset threshold minus a small hysteresis), Reset
goes low. When VCC returns above the reset threshold, Reset remains low for a time period tRP before going to
logic high. Figure 9 shows this behavior.

Feature Description (continued)
Figure 9. Reset Output Timing Diagram
7.3.3 Pullup Resistor Selection
The Reset output structure of the LP3470 is a simple open-drain N-channel MOSFET switch. A pullup resistor
(R1) must be connected to VCC.
R1 must be large enough to limit the current through the output MOSFET (Q1) below 10 mA. A resistor value of
more than 680 Ω ensures this. R1 must also be small enough to ensure a logic high while supplying all the
leakage current through the Reset pin. A resistor value of less than 68 kΩ satisfies this condition. A typical pullup
resistor value of 20 kΩ is sufficient in most applications.
7.3.4 Negative-Going VCC Transients
The LP3470 is relatively immune to short duration negative-going VCC transients (glitches). The Typical
Characteristics show the maximum transient duration versus negative transient amplitude (see Figure 6), for
which reset pulses are not generated. This graph shows the maximum pulse width a negative-going VCC
transient may typically have without causing a reset pulse to be issued. As the transient amplitude increases (in
other words, goes farther below the reset threshold), the maximum allowable pulse width decreases. A 0.1-µF
bypass capacitor mounted close to VCC provides additional transient immunity.
7.4 Device Functional Modes
7.4.1 Reset Output Low
When the VCC supply voltage is below a threshold (VRTH) voltage minus a hysteresis (VHYST) voltage, the Reset
pin will output logic low. Reset is ensured to be a logic low for VCC > 0.5 V.
7.4.2 Reset Output High
When the VCC supply voltage exceeds the reset threshold, the Reset is kept asserted for a time period (tRP)
programmed by an external capacitor (C1); after this interval Reset goes to logic high.

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The LP3470 is a micropower CMOS voltage supervisor that is ideal for use in battery-powered microprocessor
and other digital systems. It is small in size and provides maximum adjustability for power-on-reset (POR) and
supervisory functions, making it a good solution in a variety of applications. The LP3470 is available in six
standard reset threshold voltage options, and the reset time-out period is adjustable using an external capacitor
providing maximum flexibility in any application. This device can ensure system reliability and ensures that a
connected microprocessor will operate only when a minimum Vin supply is satisfied.
8.2 Typical Application
The LP3470 can be used as a simple supervisor circuit to monitor the input supply to a microprocessor as shown
in Figure 10.

8.2.2 Detailed Design Procedure
The minimum application circuit requires the LP3470 Power-On Reset Circuit IC and a pullup resistor connecting
the reset pin to VCC. The reset delay can be programmed with an additional capacitor connected from the SRT
pin to GND. See Reset Time-Out Period and Pullup Resistor Selection for information on choosing specific
values for components.
8.2.3 Application Curves
Two capacitor values for CD (0.1 µF and 1 µF) are used as examples to show the programmability of the output
time delay as shown in Figure 11 and Figure 12.

9 Power Supply Recommendations
The input of the LP3470 is designed to handle up to the supply voltage absolute maximum rating of 6 V. If the
input supply is susceptible to any large transients above the maximum rating, then take extra precautions. An
input capacitor is optional but not required to help avoid false reset output triggers due to noise.
10 Layout
10.1 Layout Guidelines
•
•
Place components as close as possible to the IC
Keep traces short between the IC and the C1 capacitor to ensure the timing delay is as accurate as possible.

(2)
Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
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)
(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/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license 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 significant portions 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. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
