About This Manual
This technical reference manual (TRM) discusses the modules and peripherals of the bq35100 device,
and how each is used to build a complete battery fuel gauge and end-of-service monitor. Content in this
TRM complements, not supersedes, information in the bq35100 Lithium Primary Battery Fuel Gauge and
End-Of-Service Monitor Data Sheet (SLUSCM6).
Notational Conventions
This document uses the following conventions:
• Hexadecimal numbers may be shown with the suffix h or the prefix 0x. For example, the following
number is 40 hexadecimal (decimal 64): 40h or 0x40.
• Registers in this document are shown in figures and described in tables.
– Each register figure shows a rectangle divided into fields that represent the fields of the register.
Each field is labeled with its bit name, its beginning and ending bit numbers above, and its
read/write properties with default reset value below. A legend explains the notation used for the
properties.
– Reserved bits in a register figure can have one of multiple meanings:
• Not implemented on the device,
• Reserved for future device expansion,
• Reserved for TI testing,
• Reserved configurations of the device that are not supported.
– Writing non-default values to the Reserved bits could cause unexpected behavior and should be
avoided.
