Hi,
I am using the BQ24193 charger.
I think that there are some contradictions at the datasheet.
At datasheet page 19 “JEITA Guideline Compliance”
There is a graph that appears to show that “Iset = 0” sets the charge current to 20% of Icharge between 0ºC and 10ºC
That seems to be contradicted at Table 12. REG05[0] JEITA_ISET that says 0 – 50%, 1 – 20%
That same graph appears to show that “Vset = 0” sets charge voltage to 4.05v between 45ºC and 60ºC
That seems also contradicted at REG07[4] JEITA_VSET that says 0 – VREG, 1 – VREG_200mV
The first issue is that the value for the bit is contradictory.
The second issue is that the graph is talking about absolute voltages and the register about 200mV difference.
I don’t know where the 4.05v is coming from. The register configuration seems to suggest that it should be 4208mV-200mV= ~4v
Then there is this tread that agrees with the graph an disagrees with the info at the register description

Right now the product released.
I don’t have an easy way of testing it.
It would be very nice to know what REG05[0] and REG07[4] do.
Thanks
