Wire Connection bq2026EVM REVA EV2300 SDQ HDQ VSS GND PROG VOUT To program the EPROM of bq2026EVM, a 12-V pulse must be generated on the SDQ line. The bq2026EVM board has an additional circuit included that permits generating this pulse when using a power supply set to 12 V and the VOUT output of the EV2300. The evaluation software controls this pulse for EPROM programming. When programming the EPROM, it is expected that a 12-V supply be connected to the bq2026EVM board at the 12-V input terminal of the bq2026EVM board. Ensure that the ground of the power supply is connected to VSS of the board. A jumper (J3) must be connected when using the EPROM programming circuit. 7.2.1 Normal Operation Normal operation includes performing any of the ROM commands, reading the 1.5K-bit EPROM and reading the EPROM Status Memory. 7.2.2 EPROM Programming To program EPROM registers, a 12-V pulse must be sent across the SDQ line during a write command. See the bq2026 data sheet (SLUS938) for a specific description of EPROM programming requirements. When programming EPROM registers, the following must be ensured: • J3 jumper is connected. • VOUT output of EV2300 is connected to PROG input of bq2026EVM board. • Power supply set to 12 V is connected across the 12-V and VSS inputs of bq2026EVM board. 8 Software Operation Run the program from the Start → Programs → Texas Instruments → bq2026 Evaluation Software menu sequence. 8.1 Evaluation Software Pages This section describes the function of each page of the evaluation program. 8.2 ROM CMD This page provides all the ROM commands for bq2026 (see Figure 6). 8.2.1 Sections Within the ROM CMD Page Read ROM — The ID ROM of the device on the SDQ communication line is displayed when READ ID is clicked.

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.
