BQ25798: SDP

Yoshinobu Kagawa
Expert 1940 points
Part Number: BQ25798
Other Parts Discussed in Thread: BQ24160

The USB input current limit for the BQ25798, but the lower limit is 500mA.
In BQ24160, the limit was 100mA until the BC1.2 determination was completed.
The 100mA limit is no longer there, but is the USB standard satisfied?





Regards,
Kagawa

    Hi Kagawa,

    We increased our SDP current to 500mA on later chargers after numerous customers complained that 100mA was not enough current to start up their system. The host can lower the input current limit to 100mA after USB enumeration if required.

    Regards,

    Jeff
