Stand-Alone Multi-Cell Lithium-Ion/Polymer Precision Protectors  
Check for Samples: bq77910  
Automatic cell balancing is provided using internal  
1
FEATURES  
50-mA cell circuits. A robust balancing algorithm  
ensures optimum performance by maintaining all cell  
voltages in balance. Balancing may be configured to  
operate at all times, only during charge, or can be  
disabled completely.  
4-, 5-, 6-, 7-, 8-, 9-, or 10 Series Cell Protection  
Individual Cell-Voltage Monitoring  
Low-Side NMOS FET Drive for Charge and  
Discharge Control  
Compatible With 1-mΩ Current-Sense Resistor  
Supply-Voltage Range From 5.6 V to 50 V  
Integrated 3.3-V Micro-Power LDO Regulator  
Low Supply Current  
Additional advanced safety features of the bq77910  
include the ability to control split power-path  
MOSFETs, an open-cell sense-line detection  
mechanism, and the ability to detect an open or  
shorted external temperature sensor.  
Normal Mode: 50 µA, Typical  
Shutdown Mode, LDO OFF: 3 µA, Typical  
Programmable Protection Functions  
Wide range of programmable detection thresholds  
and delay times  
Configurable for multiple cell types and application  
requirements:  
38-Pin TSSOP Package  
Internal 50-mA Automatic Cell Balancing  
APPLICATIONS  
Cell overvoltage  
Cell undervoltage  
Pack discharge overcurrent  
Pack discharge short circuit  
Pack charge short-circuit current  
Cordless Power Tools  
Cordless Lawn Equipment  
Electric Bikes  
UPS  
Medical Equipment  
Light Electric Vehicles (LEV)  
Variable gain (×1 or ×5) current-sense circuit  
Compatible with a wide range of current-sense  
resistors (1 mΩ to 5 mΩ typical) sized for  
application requirements  
DESCRIPTION  
The bq77910 precision protector is a complete  
stand-alone, self-contained battery-protection and  
cell-balancing device intended for Li-ion/polymer  
battery packs.  
Fixed Hardware Protection Functions  
Preset overtemperature protections  
Open-cell detection  
Open and shorted thermistor detection  
Brownout protection quickly shuts off FETs under  
low battery conditions to avoid FET overheating  
The bq77910 monitors 4 to 10 series individual cell  
voltages and provides fast-acting outputs which may  
be used to drive N-channel MOSFETs to interrupt the  
power path. Activation delays and recovery methods  
for each safety condition are fully programmable in  
non-volatile memory.
