  • RE: BQ24230: Is it possible case to terminate charging even if battery voltage doesn't reach VBAT(REG)?

    Hi Bill-san, Thank you for your support. My customer confirmed it is replicable with BQ24230EVM. He only changed RISET to 15kohm because charge current of their application is 60mA. The procedure is the following. 1) set battery voltage 4.10V and enable ch…

    Other Parts Discussed in Thread: BQ24230EVM , BQ24230 Hi Team, My customer is evaluating bq24230EVM and has a question about CHG Status Indicator. He confirmed red LED (D1: connected CHG pin) is ON during the following Vin range although a battery isn't connected…

  • RE: bq24230 / Power on process under EN1=high, EN2=low

    Hi Dick-san, Thank you for your support. I attached the plot of EN1=Low and EN2=High. It shows Q1 FET turns on when Vin exceeds UVLO threshold as datasheet shows. My customer is evaluating with bq24230EVM. Is Vout feature under EN1=high, EN2=low condition a c…

  • RE: bq24230 / safety timers function

    Hi Wenjia-san, My customer could swap the ICs of their board#1 and bq24230EVM, and confirmed the following. - EVM with the IC from board#1: 9.77h - board#1 with the IC from EVM: 9.08h As the result we can confirm the issue comes from IC itself. Is there any update…

  • RE: BQ24230 charging current issue

    Can you provide more information on the battery spec? For most of the 3.7V (nominal) lithium-ion/ LI-PO batteries, they should not be discharge down to 1.8V. Most likely the discharge voltage limit should be 3V. Have you checked the /CHG status? it should…
