9.2.2.3.2 External Cell Balancing
Internal cell balancing can only support up to 10 mA. External cell balancing provide as another option for faster
cell balancing. For details, refer to the application note, Fast Cell Balancing Using External MOSFET (SLUA420).
9.2.2.3.3 PACK and FET Control
The PACK and VCC inputs provide power to the bq40z50-R1 from the charger. The PACK input also provides a
method to measure and detect the presence of a charger. The PACK input uses a 100-Ω resistor; whereas, the
VCC input uses a diode to guard against input transients and prevents mis-operation of the date driver during
short-circuit events.
