API9221  
CAR/WALL or USB SUPPLY INPUT LITHIUM BATTERY  
CHARGER with OVP USB BYPASS and 10mA LDO  
Description  
Pin Assignments  
The API9221 has two supply inputs for highly integrated  
portable applications, enabling charging from a USB host,  
wall adapter, or car adapter.

The  
pin indicates to a host controller that a safe and  
PPR  
valid supply is connected to either VUSB or VDC. The higher  
charge current option from VDC will take priority if both  
supplies are connected. The host controller can control the

implements the constant current/constant voltage (CC/CV)  
charge algorithm for Lithium based battery cells. The  
connected cell will be charged to 4.2V with an accuracy of  
1% over the entire temperature range. The termination

Linear Lithium Ion / Lithium Polymer charging IC  
Supplied from USB host or car/wall adapter  
Overvoltage protection USB: 5.4V, wall:6.9V  
Supply inputs safe up to 28V  
The pin indicates when the termination current is  
CHG  
reached, and is reset by EN , power off, or battery below  
3.9V. The maximum charge current can be programmed  
independently via the resistors RIUSB and RIVDC  
.
Fast charging with maximum current of 1.2A  
Integrated linear regulator of 4.9V at 10mA with  
current limit  
The API9221 comes with several protection features. To  
prevent system damage, the VUSB pin uses over voltage  
protection (OVP) at 5.4V, and the VDC OVP is at 6.9V.  
Above these levels, the non-operating device is protected  
against damage up to 28V. For control and system start-up  
the API9221 has a current limited linear regulator.

Reverse current protection  
To protect the chip against excessive power dissipation,  
temperature monitoring is integrated, which folds back the  
current to a safe level. As the temperature rises, this fold-  
back begins at 125°C without completely interrupting  
charging.
