BQ25157: Missing Pin in Datasheet

Part Number: BQ25157
Other Parts Discussed in Thread: BQ25155

Heya,

In the Datasheet BQ25157 SLUSEC5 – DECEMBER 2020 the ~INT (D2) pin definition seems to be missing from "Table 7-1. Pin Functions".

What's the function of this pin?

cheers, Mathias

    Hi Matthias,

    Thanks for letting us know that the pin is missing. The /INT pin is an interrupt pin used to notify the host controller that an event has occurred, such as a fault or a charge termination, or other event. It is intended that the host controller read the registers when an INT pulse is sent to get an idea of what has occurred. You can read more about the INT function in section 9.3.9 of the BQ25157 datasheet. Otherwise you can refer to the BQ25155 datasheet which doesn't have that pin missing from the pin functions table.

    Best Regards,

    Juan Ospina
