SLUSBN7 – JANUARY 2014
GENERAL DESCRIPTION
The bq27411-G1 accurately predicts the battery capacity and other operational characteristics of a single Li-
based rechargeable cell. It can be interrogated by a system processor to provide cell information, such as state-
of-charge (SOC). The bq27411-G1 is available in several options optimized for different battery cell chemistries.
(See AVAILABLE OPTIONS table.) Configuration parameters unique to the customer's application are
programmed in OTP memory at the customer's factory using a 7.4V typical voltage applied to the PROG pin and
a set of I2C programming commands. More details are available in the SmartFlash OTP Programming
(SLUA703) document.
Information is accessed through a series of commands, called Standard Commands. Further capabilities are
provided by the additional Extended Commands set. Both sets of commands, indicated by the general format
Command( ), are used to read and write information contained within the bq27411-G1 control and status
registers, as well as its data locations.
The key to the bq27411-G1’s high-accuracy gas gauging prediction is Texas Instrument’s proprietary Impedance
Track™ algorithm. This algorithm uses cell measurements, characteristics, and properties to create state-of-
charge predictions that can achieve high accuracy across a wide variety of operating conditions and over the
lifetime of the battery.
The bq27411-G1 measures charge/discharge activity by monitoring the voltage across a small-value sense
resistor. When a cell is attached to the bq27411-G1, cell impedance is computed, based on cell current, cell
open-circuit voltage (OCV), and cell voltage under loading conditions.
The bq27411-G1 uses an integrated temperature sensor for estimating cell temperature. Alternatively, the host
processor can provide temperature data for the bq27411-G1.
To minimize power consumption, the bq27411-G1 has several power modes: INITIALIZATION, NORMAL,
SLEEP, and HIBERNATE. The bq27411-G1 passes automatically between these modes, depending upon the
occurrence of specific events, though a system processor can initiate some of these modes directly. More details
are found in the bq27411-G1 Technical Reference Manual (SLUUAS7).
