BQ297xx Cost-Effective Voltage and Current Protection Integrated Circuit for Single-  
Cell Li-Ion and Li-Polymer Batteries  
1 Features  
2 Applications  
Input voltage range pack+: VSS – 0.3 V to 12 V  
FET drive:  
– CHG and DSG FET drive output  
Voltage sensing across external FETs for  
overcurrent protection (OCP) is within ±5 mV  
(typical)  
Tablet PCs  
Mobile handsets  
Handheld data terminals  
3 Description  
The BQ2970 battery cell protection device provides  
an accurate monitor and trigger threshold for  
overcurrent protection during high discharge/charge  
current operation or battery overcharge conditions.  
Fault detection  
– Overcharge detection (OVP)  
– Over-discharge detection (UVP)  
– Charge overcurrent detection (OCC)  
– Discharge overcurrent detection (OCD)  
– Load short-circuit detection (SCP)  
Zero voltage charging for depleted battery  
Factory programmed fault protection thresholds  
– Fault detection voltage thresholds  
– Fault trigger timers  
– Fault recovery timers  
Modes of operation without battery charger  
enabled  
– NORMAL mode ICC = 4 µA  
– Shutdown Iq = 100 nA  
The BQ2970 device provides the protection functions  
for Li-ion/Li-polymer cells, and monitors across the  
external power FETs for protection due to high  
charge or discharge currents. In addition, there is  
overcharge and depleted battery monitoring and  
protection. These features are implemented with low  
current consumption in NORMAL mode operation.
