  RE: BQ7718: external delay capacitance

  Hi Holger, I apologize, I believe that is a typo in our datasheet. The delay for the BQ7718 is internal and fixed. If you are looking for a similar device with a configurable delay, the BQ7716 may fit your needs.

  RE: Battery Protection IC for LiPO 7.4V, is there any IC available for this battery Voltage.

  Hi Manimaran, There is little available for 2 cell LiFePO4. The bq4050 and bq40z50-R2 gauges can support 2 cells and LiFePO4 cells with protection features, but they are gauges and will need setup of the parameters, even if most of the device features...
