1 / 58 page  bq76PL536 www.ti.com SLUSA08A – DECEMBER 2009 – REVISED JULY 2010 3 to 6 Series Cell Lithium-Ion Battery Monitor and Secondary Protection IC for EV and HEV Applications Check for Samples: bq76PL536 1 FEATURES APPLICATIONS • Uninterruptible Power Systems (UPS) 2 • 3 to 6 Series Cell Support, All Chemistries • E-Bike and E-Scooter • Hot-Pluggable • Large-Format Battery Systems • High-Speed SPI for Data Communications • Electric and Hybrid Electric Vehicles • Stackable Vertical Interface • No Isolation Components Required Between DESCRIPTION ICs The bq76PL536 is a stackable three to six series cell • Industrial Temperature Range, –40°C to 85°C lithium-ion battery pack protector and analog front • High-Accuracy Analog-to-Digital Converter end (AFE) that incorporates a precision (ADC): analog-to-digital converter (ADC); independent cell voltage and temperature protection; cell balancing, – ±3 mV Typical accuracy and a precision 5-V regulator to power user circuitry. – 14-Bit Resolution, 6-µs Conversion Time The bq76PL536 integrates a voltage translation and – Nine ADC Inputs: 6 Cell Voltages, 1 Six-Cell precision analog-to-digital converter system to Brick Voltage, 2 Temperatures, 1 measure battery cell voltages with high accuracy and General-Purpose Input speed. – Dedicated Pins for Synchronizing The bq76PL536 provides full protection (secondary Measurements protection) for overvoltage, undervoltage, and • Configuration Data Stored in ECC-OTP overtemperature conditions. When safety thresholds Registers are exceeded, the bq76PL536 sets the FAULT • Built-In Comparators (Secondary Protector) output. No external components are needed to for: configure or enable the protection features. – Over- and Undervoltage Protection Cell voltage and temperature protection functions are independent of the ADC system. Programmable – Overtemperature Protection protection thresholds and detection delay times are – Programmable Thresholds and Delay Times stored in Error Check/Correct (ECC) OTP EPROM, – Dedicated Fault Output Signals for OV, UV, which increases the flexibility and reliability of the OT battery management system. • Cell Balancing Control Outputs With Safety The bq76PL536 is intended to be used with a host Timeout controller to maximize the functionality of the battery – Balance Current Set by External management system. However, the protection Components functions do not require a host controller. • Supply Voltage Range from 6 V to 30 V The bq76PL536 can be stacked vertically to monitor Continuous and 36 V Peak up to 192 cells without additional isolation components between ICs. A high-speed serial • Low Power: peripheral interface (SPI) bus operates between each – Typical 12-µA Sleep, 45-µA Idle bq76PL536 to provide reliable communications • Integrated Precision 5-V, 3-mA LDO through a high-voltage battery cell stack. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 PowerPAD is a trademark of Texas Instruments.
