Tool/software:
Hi all,
I am currently using the BQ25300RTER chip to charge a 1S6P lithium ion battery pack, with the lithium ion cells being INR18650-30Q. Below is a screenshot of the schematic of how this part is being used.
With a 4.5V input into this chip, the charge of our batteries will only go up to at most ~4.04V before the LED status light on the REGN and STAT pin turns off, despite our Vset resistor being set at 10kohms for a max charge of 4.2V.
Other measurements taken during this charge period before reaching this peak voltage range (LED status light is SOLID):
VBUS: 4.43V
TS: 2.107V
PMID: 4.43V
SW: 4.04V
BTST: 7.56V
BATT: 4.04V
Thanks,
Yu
