1.BQ78350 overcharge parameter question Does the threshold capacity refer to the total capacity or what? Also, what is the condition for RSOC Recovery? What is the percentage of what is 90%? TI expert reply: The release conditions of Overcharge Protection are as follows: SafetyStatus()[OC] = 1 AND continuous discharge of Recovery OR RelativeStateOfCharge() < OC:RSOC Recovery That is, when RSOC is lower than the set OC:RSOC Recovery value, it will be released >>More Questions and Answers 2. BQ78350 cannot communicate, why? Short P+ to B+, the evaluation board has a boot button, wake up the chip. You can also refer to user's guide 2.2.2 Gauge Quick Start We can connect these two chips separately with different software. You may not be able to connect at the beginning or during use. If it is a new board, it should be able to connect. >>More questions and answers 3. I am begging for the device address of BQ78350 when communicating with SMBUS.. I have just started designing battery-related products. Currently, the MCU cannot communicate with the BQ78350. The communication uses GPIO to simulate IIC, connecting the SMBUSC and SMBUSD pins of the BQ78350, and using SMBUS V1.1 communication protocol, but no matter how the MCU sends command data, BQ78350 does not respond. The initial suspicion is that the device address is incorrect. The program reads address 0x16 and writes address 0x17. The product uses the BQ78350+76930 combination to manage the battery. The 76930 has been activated, and the 78350 power supply 3.3V is normal? I beg my colleagues to help me. I am grateful. TI expert reply: Confirm the interface timing according to page 8 of the datasheet: www.ti.com.cn/.../bq78350-r1.pdf >>More questions and answers 4. Does the bq78350_R1 capacity register value suddenly change during low-temperature discharge? When doing a discharge experiment in an environment below zero degrees, the battery is fully charged. The bq78350_R1 register Relative state of charge (0x0D) will suddenly drop below 10%. The discharge current is 3A. But it can still discharge, but my capacity indicator light is not accurate. I would like to ask TI engineers, can this problem be solved? I have made the temperature of -40 degrees and -10 degrees. This problem will occur! TI expert answers >>More questions and answers 5. I am new to EV2300 and need help bqstydio communicates successfully with BQ78350, but the software reports an error and exits when I click on DATA Memroy. What can I do? TI expert answers: Generally, the default Unseal key is 04143672, and the Full Access key is FFFFFFFF. >>More questions and answers
