PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
If VSYS falls below VSYS_SHORT in boost OTG mode, BQ25638 immediately stops the boost converter, enters hiccup mode, and sets SYS_FAULT_FLAG to 1.
If the boost converter cannot recover from hiccup mode, EN_OTG bit is cleared and the device exits boost mode. The host may attempt to restart boost OTG mode by setting EN_OTG = 1.
