PRODUCTION DATA.
Required for WIN8 OS, the battery trip point (BTP) feature indicates when the RSOC of a battery pack has depleted to a certain value set in a DF register. This feature allows a host to program two capacity-based thresholds that govern the triggering of a BTP interrupt on the BTP_INT pin and the setting or clearing of the OperationStatus[BTP_INT] on the basis of RemainingCapacity().
An internal weak pull-up is applied when the BTP feature is active. Depending on the system design, an external pull-up may be required to put on the BTP_INT pin. See Electrical Characteristics: PRES, BTP_INT, DISP for details.
