MC33665ATF4AER2 NXP Battery Management IC | 48-HLQFP (7x7) | Isolated SPI, 6-Channel

Product Overview

The NXP MC33665ATF4AER2 is a high-performance battery management system (BMS) gateway IC designed for automotive and industrial applications. It acts as a bridge between the host microcontroller and up to six isolated battery cell monitoring ICs (e.g., MC33771C, MC33772C) via isolated SPI communication. Packaged in a compact 48-HLQFP (7x7 mm), it integrates a high-speed isolated SPI interface, a transformer driver for isolated power supply, and advanced diagnostic features. The device supports daisy-chain or star-topology configurations, enabling scalable BMS designs for 48V to 800V battery packs.
