Product details

The NXP MC33911BAC is a System Basis Chip (SBC) that integrates power management, CAN/LIN interfaces, and monitoring functions in a single 32-LQFP package. It is designed for automotive and industrial electronic control units (ECUs) where a regulated supply, wake-up capability, and bus communication are required on one die. Supply range is 5.5 V to 27 V; operating temperature is -40°C to 125°C.

Supply current of 4.5 mA is the quiescent draw — relevant for always-on modules that must not drain the battery when the ignition is off. A lower figure here saves standby power in body controllers and gateway modules.

ROHS3 compliant. This is a current-design-in part, not an end-of-life scavenge.

Frequently asked questions

Where can I buy the MC33911BAC?

The MC33911BAC is sourced to order against an RFQ through independent distribution. Submit an RFQ for current pricing and availability — confirmed at quote time.

What are the operating specifications of the MC33911BAC?

Supply voltage range is 5.5 V to 27 V, supply current is 4.5 mA, and operating temperature range is -40°C to 125°C. The package is a 32-LQFP (7x7) in tray format.

MC33911BAC vs MC33911B: what is the difference?

The MC33911BAC and MC33911B are variants within the same SBC family. The 'AC' suffix typically indicates a specific temperature grade or package option — the MC33911BAC is in a 32-LQFP tray package with -40°C to 125°C rating. Check the NXP ordering guide for the exact difference in feature set or qualification level between the two.
