DESCRIPTION
The Texas Instruments bq8015 Cool-GG
programmable battery management IC is the next in a
series of advanced, high-performance, reduced-
instruction-set-CPU (RISC) integrated circuits for
battery management and gas-gauge applications. In a
single CMOS IC, the bq8015 combines high-accuracy
analog measurement capabilities with a low-power
high-speed RISC processor, integrated flash memory,
and an array of peripheral and communication ports.
The program flash EPROM allows fast development of
custom implementations, and the low-power analog
peripherals improve accuracy beyond discrete
implementations. In its 38-pin TSSOP package, the
bq8015 can implement a variety of functions in a small
PCB area.
