Eight-Output Switch with Serial
Peripheral Interface I/O
The 33291L device is an eight-output, low-side power switch with 8-
bit serial input control. The 33291L is a versatile circuit designed for
automotive applications, but is well suited for other environments. The
33291L incorporates SMARTMOS technology, with CMOS logic,
bipolar/MOS analog circuitry, and DMOS power MOSFETs. The
33291L 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, and
independent shutdown of outputs.
