bq2946xx Single-Cell Protector for Li-Ion Batteries
1 Features
3 Description
•
The bq2946xx family of products is a secondary-level
overvoltage monitor and protector for Li-Ion battery
pack systems. The cell is monitored for overvoltage
condition and triggers an internal counter once the
OVP threshold is exceeded; after a fixed set delay,
the out is transitioned to a high level. The output is
reset (goes low) if the cell voltage drops below the
set threshold minus the hysteresis.

8 Detailed Description
8.1 Overview
The bq2946xx is a second-level overvoltage (OV) protector for a single cell. The cell voltage is compared to a
protection voltage threshold, VOV. The protection threshold is preprogrammed at the factory with a range from
3.85 V to 4.65 V. When the OVP is triggered, the OUT pin goes high to activate an external N-channel FET,
which conducts a low-impedance path to blow a fuse.

8.3 Feature Description
Cell Voltage (V)
V1–VSS)
The method of overvoltage detection is comparing the cell voltage to an OVP threshold voltage VOV. Once the
cell voltage exceeds the programmed fixed value VOV, the delay timer circuit is activated. This delay (tDELAY) is
fixed for 4 seconds for the bq294602 device. When these conditions are satisfied, the OUT terminal is
transitioned to a high level. This output (OUT) is released to a low condition if the cell input (V1) is below the
OVP threshold minus the VHYS.

8.3.1 Sense Positive Input for V1
This is an input to sense single battery cell voltage. A series resistor and a capacitor across the cell is required
for noise filtering and stable voltage monitoring.

Feature Description (continued)
8.3.2 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.
8.3.3 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.
8.3.4 Thermal Pad, PWRPAD
For correct operation, the power pad (PWRPAD) is connected to the VSS terminal on the PCB.
8.4 Device Functional Modes
8.4.1 NORMAL Mode
When the cell voltage is below the overvoltage threshold, VOV, the device operates in NORMAL mode. The OUT
pin is inactive and is low.
8.4.2 OVERVOLTAGE Mode
OVERVOLTAGE mode is detected if the cell voltage exceeds the overvoltage threshold, VOV, for configured OV
delay time. The OUT pin is activated, internally pulled high, after a delay time, tDELAY. An external FET then
turns on, shorting the fuse to ground, which allows the battery and/or charger power to blow the fuse. When the
cell voltages fall below (VOV – VHYS), the device returns to NORMAL mode.
8.4.3 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 V1
(see Figure 6). The delay timer is greater than 10 ms, but considerably shorter than the timer delay in normal
operation. To exit CTM, remove the VDD to V1 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 CTM. Also avoid exceeding Absolute Maximum Voltage for the cell voltage
(V1–VSS). Stressing the pins beyond the rated limits may cause permanent damage to
the device.
Figure 6 shows the timing for the CTM.

9 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.
9.1 Application Information
The bq2946xx devices are a family of second-level protectors used for overvoltage protection of the single-cell
battery pack in the application. The OUT pin drives a NMOS FET that connects the fuse to ground in the event of
a fault condition. This provides a shorted path to use the battery and/or charger power to blow the fuse and cut
the power path.
9.1.1 Application Configuration
Changes to the ranges stated in Table 1 may impact the accuracy of the cell measurements. Figure 8 shows
each external component.
NOTE
Connect VSS (pins 3 and 4) externally to the CELL– terminal.

11 Layout
11.1 Layout Guidelines
1. Ensure the RC filters for the V1 and VDD pins are placed as close as possible to the target terminal,
reducing the tracing loop area.
2. The VSS pin should be routed to the CELL– terminal.
3. Ensure the trace connecting the fuse to the gate, source of the NFET to the Pack is sufficient to withstand
the current during a fuse blown event.

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.

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.
