Dropout Voltage vs Load Current for New Chip”，4V输入，3.3V输出满足Dropout电压要求，芯片最大输出电流150mA。 对于您的问题，是否做过交叉验证，以证明问题跟随芯片走。 如果您怀疑芯片有质量问题，且是从TI官网购买的，请在下面链接申请失效性分析。 www.ti.com/.../createReturn.tsphttps://e2echina.ti.com/support/power-management/f/power-management-forum/1078846/bq76952evm-bq76952evm-failed-to-connect-to-bqstudio/3885894Mon, 15 Jun 2026 02:24:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:55c2f2b8-d017-451f-9260-6bbdeaf9d63aAliceHello, I do not recommend using the EV2300 with the BQ76952. There were multiple updates made to the EV2400 firmware to ensure compatibility with the BQ76952 family, so there may be some non-obvious issues when using the EV2300.
