DESCRIPTION
The bq7718xy family of products is an overvoltage monitor and protector for Li-Ion battery pack systems. Each
cell is monitored independently for an overvoltage condition.
In the bq7718xy device, an internal delay timer is initiated upon detection of an overvoltage condition on any cell.
Upon expiration of the delay timer, the output is triggered into its active state (either high or low depending on the
configuration). For quicker production-line testing, the bq7718xy device provides a Customer Test Mode with
greatly reduced delay time.

PIN DETAILS
In the bq7718xy device, each cell is monitored independently. Overvoltage is detected by comparing the actual
cell voltage to a protection voltage reference, VOV. If any cell voltage exceeds the programmed OV value, a timer
circuit is activated. When the timer expires, the OUT terminal goes from inactive to active state.
Cell Voltage (V)
(V5–V4, V4–V3, V3–V2, V2–V1, V1–VSS)
For NCH Open Drain Active Low configurations, the OUT pin pulls down to VSS when active (OV present) and is
high impedance when inactive (no OV).

Figure 2. Timing for Overvoltage Sensing
Sense Positive Input for Vx
This is an input to sense each single battery cell voltage. A series resistor and a capacitor across the cell for
each input is required for noise filtering and stable voltage monitoring.
Output Drive, OUT
This terminal serves as the fault signal output, and may be ordered in either active HIGH or LOW options.
Supply Input, VDD
This terminal is the unregulated input power source for the IC. A series resistor is connected to limit the current,
and a capacitor is connected to ground for noise filtering.

CUSTOMER TEST MODE
Customer Test Mode (CTM) helps to reduce test time for checking the overvoltage delay timer parameter once
the circuit is implemented in the battery pack. To enter CTM, VDD should be set to at least 10 V higher than V5
(see Figure 13). The delay timer is greater than 10 ms, but considerably shorter than the timer delay in normal
operation. To exit Customer Test Mode, remove the VDD to V5 voltage differential of 10 V so that the decrease
in this value automatically causes an exit.
CAUTION
Avoid exceeding any Absolute Maximum Voltages on any pins when placing the part
into Customer Test Mode. Also avoid exceeding Absolute Maximum Voltages for the
individual cell voltages (V5–V4), (V4–V3), (V4–V3), (V3–V2), (V2–V1), and (V1–VSS).
Stressing the pins beyond the rated limits may cause permanent damage to the
device.
Figure 13 shows the timing for the Customer Test Mode.

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.
