bq76PL536 - industry's highest accuracy lithium-ion battery monitor for electric mobility, power tools and UPS
/ contains 3x video / Texas Instruments 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.

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.
