16-cell EV/HEV integrated battery monitor and protector with passive balancing

TIDA-00717

Overview

Stackable monitors and protectors used in large lithium-ion batteries to provide monitoring, balancing and communication functions. Each bq76PL455A-Q1 EVM can manage 8 to 16 cells (12V minimum) in Li-ion battery applications. Up to 16 bq76PL455A-Q1 EVM modules can be stacked. The system provides fast cell balancing, diagnostic functions and modules for controller communication. An independent protection circuit is also integrated.

characteristic
