TI introduces industry's highest accuracy lithium-ion battery monitor

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-preu. 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
