Feature Description (continued)
If the cell overvoltage condition is removed before the external capacitor reaches the reference voltage, the
internal current source is disabled and an internal discharge block is employed to discharge the external
capacitor down to 0 V. In this instance, the OUT pin remains in a low state.
8.3.2 Cell Voltage > VPROTECT
When one or both of the cell voltages rises above VPROTECT, the internal comparator is tripped, and the delay
begins to count to td. If the input remains above VPROTECT for the duration of td, the bq2920x output changes from
a low to a high state, by means of an internal pull-up network, to a regulated voltage of no more than 9.5 V when
IOH = 0 mA.
The external delay capacitor should charge up to no more than the internal LDO voltage (approximately 5 V
typically), and will fully discharge in approximately under 100 ms when the overvoltage condition is removed.
Figure 4. Timing for Overvoltage Sensing
8.3.3 Cell Connection Sequence
NOTE
Before connecting the cells, populate the overvoltage delay timing capacitor, CCD.
The recommended cell connection sequence begins from the bottom of the stack, as follows:
1. GND
2. VC1
3. VC2
While not advised, connecting the cells in a sequence other than that described above does not result in errant
activity on the OUT pin. For example:
1. GND
2. VC2 or VC1
3. Remaining VCx pin
8.3.4 Cell Balance Enable Control
To avoid prematurely discharging the cells, it is recommended to turn off (pull high) the active-low Cell Balance
Enable Control pin at lower State of Charge (SOC) levels.
