DESCRIPTION

· The bq76PL536 is a stackable three to six series cell lithium-ion battery pack protector and analog front end (AFE).
· It includes a precision analog-to-digital converter (ADC), independent cell voltage and temperature protection, cell balancing, and a precision 5-V regulator.
· Designed for use with a host controller to maximize battery management system functionality, though protection functions do not require a host controller.
· Can be stacked vertically to monitor up to 192 cells without additional isolation components between ICs.

FEATURES

· Supports 3 to 6 series cells, all chemistries, and is hot-pluggable.
· High-speed SPI for data communications and stackable vertical interface.
· Industrial temperature range from -40°C to 85°C.
· High-accuracy ADC with ±3mV typical accuracy, 14-bit resolution, and 6-µs conversion time.
· Nine ADC inputs: 6 cell voltages, 1 six-cell brick voltage, 2 temperatures, 1 general-purpose input.
· Built-in comparators for overvoltage, undervoltage, and overtemperature protection.
· Configuration data stored in ECC-OTP registers.
· Supply voltage range from 6V to 30V continuous and 36V peak.
· Low power consumption: typical 12-µA sleep, 45-µA idle.
· Integrated precision 5-V, 3-mA LDO.

APPLICATIONS

· Uninterruptible Power Systems (UPS).
· E-Bike and E-Scooter.
· Large-Format Battery Systems.
· Electric and Hybrid Electric Vehicles.
