Part Number: BQ4050
Hi,
1)how can i control the duty cycle of the cell balancing fets? if i cant control it , how does the bq4050 set the duty cycle
2) the bq4050 controls the balance fet of only one battery for each time step ? it's not able to "short" with 200 ohm fet 2 batteries at the same time?
3) for example, cell bal. threhsold is 3.3 v and call bal. window is 0.1V, all the batteries have a voltage between 3.3 and 3.4 volts, and the cell balancing is enabled,
then, one cell is charged to 3.401 volts, does it mean that now the threshold for Cell bal. is 3.4 volts and all the cells must rise above 3.4 volts in order to continue the balancing? (lets assume that the voltage difference is bigger than minimum for CB for the whole charging process.
thank you for your help!
