System Basis Chip for 12V/24V automotive domains
The NXP MC33910G5AC is a System Basis Chip (SBC) integrating multiple power-management and interface functions into a single 32-LQFP package. It is designed for direct connection to automotive battery rails, accepting a supply voltage from 5.5V to 27V, which covers both 12V and 24V nominal systems without an external pre-regulator. The device draws a typical supply current of 4.5mA, making it suitable for always-on body-control modules where quiescent draw matters. The operating temperature range of -40°C to 125°C qualifies it for under-hood and engine-bay environments.
Package and mounting — 32-LQFP (7x7 mm)
Housed in a 32-lead LQFP with a 7x7 mm body, the MC33910G5AC uses a standard 0.8 mm pitch footprint. No exposed pad is present, so thermal dissipation relies on the leadframe and board copper. The small footprint suits space-constrained ECU designs where a separate regulator and transceiver would occupy more area.
Lifecycle and compliance — active, ROHS3
It is fully ROHS3 compliant, which simplifies procurement for designs targeting European or global automotive markets. No second-source or direct replacement is listed in the official documentation; for dual-sourcing strategies, consult NXP's SBC portfolio for functionally similar devices in the same package family.
