PRODUCTION DATA
VSYS pin is monitoring the system voltage, when Vsys is lower than 2.4V, after 2ms deglitch time, the charger will be shut down for 500ms. The charger will restart for 10ms and measure Vsys again, if it is still lower than 2.4V, the charger will be shut down again. This hiccup mode will be tried continuously, if the charger restart is failed for 7 times in 90 second, the charger will be latched off. REG0x20[3] will be set to 1 to report a system short fault. The charger only can be enabled again once the host writes REG0x20[3]= 0.
The charger system short hiccup mode can be disabled by writing REG0x00[6]= 1.
