Eight-Output Switch with Serial Peripheral Interface I/O
The 33291 device is an eight-output, low-side power switch with 8bit serial input control. The 33291 is a versatile circuit designed for automotive applications, but is well suited for other environments. The 33291 incorporates SMARTMOS technology, with CMOS logic, bipolar/MOS analog circuitry, and DMOS power MOSFETs. The 33291 interfaces directly with a microcontroller to control various inductive or incandescent loads.
