COMMUNICATIONS
SMBus
The bq78PL116 uses the industry-standard Smart Battery System’s two-wire System Management Bus (SMBus)
communications protocol for all external communication. SMBus version 1.1 is supported by the bq78PL116, and
includes clock stretching, bus fault time-out detection, and optional packet error checking (PEC). For additional
information, see the www.smbus.org and www.sbs-forum.org Web sites.
Smart Battery Data (SBData)
The bq78PL116 supports Smart Battery System's (SBS) Smart Battery Data Specification 1.1. See the
SBS/SMBus site at www.sbs-forum.org for further information regarding these specifications.
This SBS Data (SBData) specification defines read/write commands for accessing data commonly required in
laptop computer applications. The commands are generic enough to be useful in most applications.
The bq78PL116 provides a wealth of data beyond the standard set of SBData (0x00 - 0x23) through Extended
SBData Commands. See the following table for a listing of the SBData commands and the default set of
Extended SBData (0x3C - 0x58). SBData command locations 0x80 and 0x81 are used to implement some of the
features unique to the bq78PL116. Refer to the bq78PL116 Technical Reference Manual Document for additional
details on compliance to SBData and how to take advantage of the data and controls specific to bq78PL116.
THERMAL PAD
