DESCRIPTION  
The bq24190 is a highly-integrated switch-mode battery charge management and system power path  
management device for 1 cell Li-Ion and Li-polymer batteries in a wide range of tablet and other portable  
devices. Its low impedance power path optimizes switch-mode operation efficiency, reduces battery charging  
time and extends battery life during discharging phase. The I2C serial interface with charging and system settings  
makes the device a truly flexible solution.  
The bq24190 supports a wide range of input sources, including standard USB host port, USB charging port, and  
high power DC adapter. To set the default input current limit, the bq24190 detects the input source following the  
USB battery charging spec 1.2. The bq24190 is compliant with USB 2.0 and USB 3.0 power spec with input  
current and voltage regulation. Meanwhile, the bq24190 supports USB On-the-Go operation by supplying 5V on  
VBUS with current limit up to 1.3A.  
The power path management regulates the system slightly above battery voltage but does not drop below 3.5V  
(programmable). With this feature, the system keeps operating even when the battery is completely depleted or  
removed. When the input source current or voltage limit is reached, the power path management automatically  
reduces the charge current to zero and then starts discharging the battery until the system power requirement is  
met. This supplement mode operation keeps the input source from getting overloaded.
