Part Number: BQ24230EVM Other Parts Discussed in Thread: BQ24232EVM , BQ24232 Tool/software: Hi Team,
There is a termination issue on BQ24230EVM. I think that the termination is not detected under condition of jumper setting as follows. JMP1=open, JMP2…
Other Parts Discussed in Thread: BQ24230EVM , BQ24230 Hi Team, When I apply 5V supply for bq24230EVM, CHG LED(D1) emits light for a moment even if battery is unconnected. Is it normal function for bq24230? I would also like to know why it occures. Best…
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…
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…
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…
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…
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…
