MC3377x Battery Junction Box Controller ICs

NXP Semiconductors MC3377x Battery Junction Box Controller ICs are designed to integrate sense, think, and act capabilities on a single device. These ICs redundantly measure currents, temperatures and voltages, and process the results to detect application fault events and trigger reactions without a microcontroller. The MC3377x ICs support an isolated daisy chain (TPL3) or a Serial Peripheral Interface (SPI) for communication with the microcontroller. The ICs also support Automotive Safety Integrity Level (ASIL D) for the features.
