PRODUCTION DATA

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 BQ29209-Q1 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.
