Hello team,
Regarding the contents of the data sheet (REV.A) of BQ25703A, there was a content that was suspected to be incorrect, so I would like to confirm it for the customer.
(1) I2C address is different
As the I2C address of the device, there is a description of "D6h (1101101_X)" on p.31.
But the customer couldn't access it even with the binary notation "1101101_X".
As a result of the operation check, they were able to access with "110_1011_x" in binary notation.
(2) I2C Timing Requirements are incorrect
P.18, p.19
SCLK pulse width High --- min 4.7us
SCLK pulse width Low ---- min 4.7us
Clock Frequency ----- min 100KHz, max 400KHz
If the clock frequency is max 400kHz, the minimum value of SCLK pulse width (High / Low) should be 1.25us. At min100kHz, the SCLK pulse width (Hihg / Low) should be 5us.
Therefore, if the pulse width min 4.7us is correct, the maximum Clock Frequency would be 100kHz.
On the other hand, if the Clock Frequency is correct, the minimum pulse width of SCLK should be smaller than 1.25us.
It would be helpful if you could confirm which is correct, the description or the customer's point.
I am looking forward to hearing from you.
Best Regards,
Ryotaro Fukui
