These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam  
during storage or handling to prevent electrostatic damage to the MOSFET gates.  
DESCRIPTION (CONTINUED)  
The MODE pin selects the priority of the input sources. If an input source is not available, then the battery is  
selected as the source. With the MODE pin high, the bq24070/1 attempts to charge from the input at the charge  
rate set by ISET1 pin. With the MODE pin low, the bq24070/1 defaults to USB charging at the charge rate. This  
feature allows the use of a single connector (mini-USB cable), where the host programs the MODE pin  
according to the source that is connected (AC adaptor or USB port). Table 1 summarizes the MODE pin  
function.

Web site at www.ti.com.  
(2) The RHL package is available in the following options:  
R - taped and reeled in quantities of 3,000 devices per reel.  
T - taped and reeled in quantities of 250 devices per reel.  
(3) This product is RoHS compatible, including a lead concentration that does not exceed 0.1% of total product weight, and is suitable for  
use in specified lead-free soldering processes. In addition, this product uses package materials that do not contain halogens, including  
bromine (Br) or antimony (Sb) above 0.1% of total product weight.  
(4) If AC < VO(OUT-REG), the AC is connected to the OUT pin by a P-FET, (Q1).
