BQ24296M: BQ24296M default max charging current

John Robertson
Prodigy 20 points
Part Number: BQ24296M
Other Parts Discussed in Thread: TUSB322I, BQ25616

Table-3 of the datasheet notes default charging current 2.048A.
Table-6 mentions if PSEL = Lo, 3A (111) IINLIM

Is it possible to enable 3A current autonomously (like TUSB322I + BQ25616 ILIM) or requires I2C write to REG02?

- PSEL = 0
- OTG = 0 
- CE = 0
- ILIM = 158-ohm to gnd
- QON = Hi-Z

    Hi John,

    To clarify, table-6 describes the Input Current Limit, which can be a default of 3 A if Psel is pulled low. 3 amps of Charging Current does require and I2C write to REG02. Data value 100111 to the ICHG bit field will result in a 3008 mA charge current, which is the highest supported current. 

    Best Regards,
