MC33665ATF4AE NXP Battery Management IC | 48-HLQFP (7x7) | Isolated Network, SPI Interface

Product Overview

The MC33665ATF4AE is a high-performance isolated network communication controller from NXP Semiconductors, designed specifically for battery management systems (BMS) in electric vehicles (EVs), hybrid electric vehicles (HEVs), and energy storage systems. It acts as a bridge between the host microcontroller and multiple battery cell monitoring ICs (such as the MC33771C or MC33772C) via a transformer-based isolated daisy-chain interface. The device supports both SPI and I²C communication with the host, and provides galvanic isolation up to 5 kV, ensuring safe and reliable data transfer in high-voltage environments. Housed in a compact 48-HLQFP (7x7 mm) package, it is ideal for space-constrained automotive and industrial applications.
