NXP Semiconductors MC33XS2410EL

The MC33XS2410 is a four channel self-protected high-side switch. Featuring advanced digital monitoring and control function, the device is operational from 3.0 V to 60 V. As a result of high-level integration, the embedded 12-bit analog-to-digital converter enables a drastically simplified hardware design and MCU software control.

The device is controlled by SPI port for configuration, monitoring and diagnostics of the outputs. Whenever communication with the MCU is lost, the device enters a safe operation mode, but remains operational, controllable and protected.

Qualified in accordance with AEC Q100 grade 1
