• High Accuracy Analog Interface with Two provides protection and control for 2-series cell Li-Ion
Independent ADCs: battery packsina single TSSOP package.
High Resolution 16-Bit Integrator for Implementing the optimum balanceof quick response
Coulomb Counting analog hardware-based monitoring and control along
16-Bit Delta-Sigma ADC witha 16-Channel with an integrated fast CPU provides the ideal
Multiplexer for Voltage, Current, and pack-basedor in-system Li-Ion battery solution. The
bq28400 also provides flexible user programmable
Temperaturesettings storedin flash memory for controlof critical
• High Side Protection FET Drive system parameters suchas overcurrent, short circuit,
• Fully Integrated Internal Clock Synthesizer under/overvoltage, and over/undertemperature
with No External Components Required conditions.
Two-Wire SMBus v1.1 Compliant The bq28400 communicates with the system host via
Communications a two-wire SMBus 1.1 compatible interface, providing
high-accuracy reporting and controlof battery pack
operation. The FET drive and TSSOP package
enablea lower cost and small footprint solution along
witha simple layout and routing on narrow pack
PCBs.
