These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) The bq24085/6/7/8 are only available taped and reeled. Add suffix R to the part number for quantities of 3,000 devices per reel (e.g.,
bq24085DRCR). Add suffix T to the part number for quantities of 250 devices per reel (e.g., bq24085/6/7DRCT).
(2) This product is RoHS compatible, including a lead concentration that does not exceed 0.1% of total product weight, and is suitable for
use in specified lead-free soldering processes. In addition, this product uses package materials that do not contain halogens, including
bromine (Br) or antimony (Sb) above 0.1% of total product weight.
(3) For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TI
website at www.ti.com.

(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute–maximum–rated conditions for extended periods may affect device reliability.
(2) The bq24085/6/7/8 family can withstand up to 18 V maximum continuously, 20 V for maximum of 2000hrs and 26 V for a maximum for
87 hours.
