DESCRIPTION
The bq2945xy family of products is a secondary level voltage monitor and protector for Li-Ion battery pack
systems. Each cell is monitored independently for an overvoltage condition. Based on the configuration, an
output is triggered after a fixed delay if any one of the two or three cells has an overvoltage condition. This output
will be triggered into a high state after an overvoltage condition has satisfied the specified delay timer.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

PIN DETAILS
Description
The voltage sensing for each cell is done independently using a multiplexer. The method of overvoltage detection
is comparing the voltage to an overvoltage protection voltage VOV. Once the voltage exceeds the programmed
fixed value, the delay timer circuit is activated. This delay (tDELAY) is fixed for either a 4-s or 6.5-s delay. When
these conditions are satisfied, the OUT terminal is transitioned to a high level. This output (OUT) is released to a
low condition if all of the cell inputs (Vx) are below the OVP threshold minus the Vhys.

OUT (V)
Figure 1. 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
The gate of an external N-Channel MOSFET is connected to this terminal. This output transitions to a high level
when an overvoltage condition is detected and after the programmed delay timer. The out will reset to a low level
if the cell voltage falls below the VOV threshold before the fixed delay timer expires.
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 V3
(see Figure 10). 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 VC3 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 (V3–V2), (V2–V1), and (V1–VSS). Stressing the pins beyond
the rated limits may cause permanent damage to the device.

(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.

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.
