DALLAS, May 19, 2011 /PRNewswire/ -- Texas Instruments
Incorporated (TI) (NYSE: TXN) today introduced a battery management
integrated circuit that increases the life of rechargeable
lithium-ion battery packs and maximizes available energy for hybrid
and electric vehicles, power tools and uninterruptible power source
(UPS) applications. The stackable bq76PL536 battery monitor,
balancer and protector incorporates analog-to-digital converters
for independent cell voltage and temperature protection, cell
balancing and isolated chip-to-chip communication. The device
intelligently measures battery cell voltages to 1-mV accuracy,
which is needed for demanding new lithium chemistries. For
information or to order, visit www.ti.com/bq76pl536-pr. For the
AEC-Q100 automotive-qualified version, see
www.ti.com/bq76pl536Q1-pr.
The bq76PL536 also provides full secondary protection for over
voltage, under voltage and over temperature conditions. When safety
thresholds are exceeded, the device sets the fault and alert
outputs independently of the normal communication channel. No
external components are needed to configure or enable the
protection features.
Key features and benefits
- +/-1-mV typical voltage measurement accuracy increases battery
gas gauging accuracy to determine remaining capacity,
cell-balancing efficiency and system safety.
- Integrated secondary level of protection for over-voltage,
under-voltage and over-temperature conditions increases safety
without adding component cost.
- Vertically stackable to monitor up to 192 cells without
additional isolation components between ICs.
- High-speed 1-Mb/s serial peripheral interface (SPI) bus
operates between each bq76PL536 to provide reliable
communication.
- AEC-100 production flow, reliability and testing for automotive
applications.
- Cell-balancing drivers extend the available capacity and
lifetime of the battery pack by maintaining state of charge and
capacity balance.
