It is designed to deliver up to 200 mA (bq2430x) or 700 mA (bq2431x/8x) of charge current to Li-ion or Li-polymer applications. The charger front-end protection current is designed to 300 mA (bq2430x) or 1000 mA (bq2431x) or no limit (bq2438x). The bq2430x/1x8x protects the charging system against three types of failures: input overvoltage when the AC adapter fails to regulate its voltage; load overcurrent when failures such as a short-circuit occurs in the charging system; and battery overcharge. In addition, bq2430x provide a PFET gate drive signal to an external PFET for input reverse-polarity protection. For details, see the relevant bq2430x/1x/8x data sheet. 1.3 1.4 1.5 I/O Description Jack Description J1-DC+ AC adapter, positive output J1-DC– AC adapter, negative output, ground J2-OUT CFE OUT pin J2-DC– CFE VSS pin, ground J2-BAT+ Connect to battery positive output J2-FAULT CFE FAULT pin J3-CHGIN bq24080 IN pin, connect to external power supply positive output J3-DC– bq24080 VSS pin, ground J4-BAT+ Connect to battery positive output J4-BAT– Connect to battery negative output, ground Controls and Key Parameters Setting Jack Description Factory Setting JMP1 CFE input voltage is indicated by LED.

Ensure that sufficient thermal vias are right underneath the IC, connecting to the ground plane on the other layers. 2. The high-current charge paths into IN and from OUT pins must be sized appropriately for the maximum charge current in order to avoid voltage drops in these traces. 3. Decoupling capacitors for IN and OUT pins should be placed on the board and the interconnections to the IC made as short as possible. 4. Resistors for ILIM and VLIM must be placed close to the corresponding IC pins and the interconnections to the IC made as short as possible.

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.
