BQ24196: about mode switching

Part Number: BQ24196

Hello E2E,

Please let me know about OTG operation for BQ24196.
When switch the mode from charge to OTG 5V output, is it necessary to change REG [5:4] from 0:1 to 1:0?
Is it impossible to control by simply switching the OTG pin logic?

Regards,
ACGUY

    Hi

    Below list is OTG enable condition. Please look at item3, you should (1) pull OTG pin high and (2) program REG01[5:4] to 10

    Thanks

    1. BAT above BATLOWV threshold (VBATLOWV set by REG04[1])

    2. VBUS less than BAT+VSLEEP (in sleep mode)

    3. Boost mode operation is enabled (OTG pin HIGH and REG01[5:4] = 10)

    4. After 220-ms delay from boost mode enable
