SLUSDQ4 April 2019 BQ79606A-Q1
The BQ79606A-Q1 operates as a stand alone device or as a stack of up to 64 devices (1 base device and 63 stack devices) to monitor large stacks of Li-Ion cells. In a stack configuration, the single host, such as a microcontroller, communicates with a single "base" device to interface with the entire stack. The BQ79606A-Q1 integrates a daisy chain interface to allow all devices to communicate with the base device. The base device interfaces with the host through a UART communication interface and a fault signaling output (NFAULT). In stand-alone operation, the daisy-chain communication is disabled and the host communicates only with the single device.
