Figure 5. Low Dropout Single-Cell Li-Ion/Li-Pol Charger
The bq2420x supports a precision Li-Ion or Li-Pol charging system suitable for single-cells with either coke orgraphite anodes. Figure 5 shows an application schematic and Figure 6 shows the typical charge profile.
The bq24200 and bq24201 continuously monitors battery temperature by measuring the voltage between the TSand VSS pins. A negative- or a positive-temperature coefficient thermistor (NTC, PTC) and an external voltagedivider typically develop this voltage (see Figure 5 ). The bq24200 and bq24201 compare this voltage against theinternal V
(TS1)
and V
(TS2)
thresholds to determine if charging is allowed (see Figure 7 ). The temperature sensingcircuit is immune to any fluctuation in Vcc since both the external voltage divider and the internal thresholds arereferenced to Vcc.
Once a temperature outside the V
(TS1)
and V
(TS2)
thresholds is detected the bq24200 and bq24201 immediatelysuspend the charge. The bq24200 and bq24201 suspend the charge by turning off the power FET and holdingthe timer value (i.e., timers are NOT reset). Charge is resumed when the temperature returns to the normalrange.

TS1
and V

thresholds to pin TS disables the temperature-sensing feature. Also applying a voltagebetween (V
CC
– 0.3 V) and Vcc suspends the charge and places the IC in the low-power standby mode.
Figure 7 shows the operational flow chart for the bq2420x.
Upon power-up, if the battery voltage is below the V
(LOWV)
threshold, the bq2420x applies a pre-charge current,I
(PRECHG)
, to the battery. This feature revives deeply discharged cells. The bq2420x activates a safety timer,t
(PRECHG)
, during the conditioning phase. If V
(LOWV)
threshold is not reached within the timer period, the bq2420xturns off the charger and enunciates FAULT on the STAT pin. In the case of a FAULT condition, the bq2420xreduces the current to I(
DETECT)
. I
(DETECT)
is used to detect a battery replacement condition. Fault condition iscleared by POR or battery replacement.
Following a successful pre-conditioning, the bq2420x relies on an external current-limited supply to limit thecharge current to the cell. The bq2420x continues this phase until the battery reaches the voltage regulationphase.
During this phase (and all other phases of operation) in order to protect the integrated powerFET, the internalshort circuit and thermal protection circuits are active.
The voltage regulation feedback is through the BAT pin. This input is tied directly to the positive side of thebattery pack. The bq2420x monitors the battery-pack voltage between the BAT and VSS pins. The bq2420x isoffered in two fixed-voltage versions: 4.1 V and 4.2 V.
As a safety backup, the bq2420x also monitors the charge time in the voltage regulation mode. If taper current isnot detected within this time period, t
(CHG)
, the bq2420x turns off the charger and enunciates FAULT on the STATpin. Fault condition is cleared by POR or battery replacement. Note that the safety timer is reset if the bq2420x isforced out of the voltage regulation mode.
The bq2420x monitors the charging current during the voltage regulation phase. Once the taper threshold,I
(TAPER)
, is detected the bq2420x initiates the taper timer, t
(TAPER)
. Charge is terminated after the timer expires.The bq2420x resets the taper timer in the event that the charge current returns above the taper threshold,I
(TAPER)
.
In addition to the taper current detection, the bq2420x terminates charge in the event that the charge current fallsbelow the I
(TERM)
threshold. This feature allows for quick recognition of a battery removal condition.

After a charge termination, the bq2420x restarts the charge once the voltage on the BAT pin falls below theV
(RCH)
threshold. This feature keeps the battery at full capacity at all times.
The bq2420x enters the low-power sleep mode if the Vcc is removed from the circuit (i.e., the Vcc and IN pinsare floating). For applications where these pins are not floating, placing a low-power 10 Ω(1/16 W) between theIN and VCC pins ensures the V
(SLP)
conditions are met (see Figure 9 ).This feature prevents draining the batteryduring the absence of V

The CE pin on bq24202, bq24203, bq24204 and bq24205 can be used to enable or suspend the charge. Chargeis enabled if the voltage V

suspends the charge. During a chargesuspend mode, the internal powerFET is turned off and all timers are reset.
The STAT pin on the bq2420x, indicates various conditions of operation. These conditions are summarized inTable 1 .

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 JESD46C and to discontinue any product or service per JESD48B. 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 which meet ISO/TS16949 requirements, mainly for automotive use. Components which
have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such
components to meet such requirements.
