For applications that require more balancing current, the BQ79606A-Q1supports external FETs. Select the Balance FET based on the following criteria:
RDSON is not a major concern, but must be taken into account when choosing the resistors. Power dissipation of the FET is a function of discharge current selected and the resistance value of FET at that worst-case condition, usually at hot temperature. I2R calculates the power dissipated. Take care in selecting size if using very small packages. A series resistor between the CB pin and the FET gate limits current going into the FET during hot plug or other transient events. The VGS capacitor ensures the FET is not turned on during hotplug due to the miller capacitance of the FET. Also note that P and N FET combination can be used.
