MC33298 Octal Serial Switch with Serial Peripheral Interface I/O
The MC33298 is an eight output low side power switch with 8 bit serial input control. The MC33298 is a versatile circuit designed for automotive applications, but is well suited for other environments. The MC33298 incorporates SMARTMOS™ technology, with CMOS logic, bipolar/MOS analog circuitry, and DMOS power MOSFETs. The MC33298 interfaces directly with a microcontroller to control various inductive or incandescent loads. The circuit’s innovative monitoring and protection features are: very low standby current, cascadable fault reporting, internal 65 V clamp on each output, output specific diagnostics, and independent shutdown of outputs.
