MC33888FB Description

Short technical summary and product information.

The MC33888FB from NXP Semiconductors is a power distribution switch designed for automotive applications. It integrates four high-side MOSFETs (two 10 mΩ and two 40 mΩ) and eight low-side drivers (600 mΩ each) in a single package.

 

Control and diagnostics are managed via a 16-bit SPI interface. Each high-side output can also be controlled individually using a parallel input for PWM applications. The low-side outputs share a single configurable direct input.

 

Key features include a wide operating voltage range of 6.0 V to 27 V, SPI control for overcurrent limit, current sense, open load detection, and watchdog timeout. It also provides SPI reporting for program status and faults, along with high-side analog current feedback.

 

The device is available in a 64-PQFP package and is surface-mount compatible. It offers various fault protection mechanisms, including current limiting, open load detection, and overvoltage protection.
