Product Summary
The MC33291EG is an eight output, low side power switch with 8-bit serial input control. The MC33291EG is a versatile circuit designed for automotive applications, but is well suited for other environments. The MC33291EG incorporates SMARTMOS technology, with CMOS logic, bipolar/MOS analog circuitry, and DMOS power MOSFETs. The MC33291EG interfaces directly with a microcontroller to control various inductive or incandescent loads. The circuit’s innovative monitoring and protection features include: Very Low Standby Current, SPI Cascade Fault Reporting Capability, Internal 53 V Clamp on Each Output, Output Specific Diagnostics, Independent Shutdown of Outputs.
