Product Summary
The MCZ33291 device is an eight-output, low-side power switch with 8-bit serial input control. The MCZ33291 is a versatile circuit designed for automotive applications, but is well suited for other environments. It incorporates SMARTMOS technology, with CMOS logic, bipolar/MOS analog circuitry, and DMOS power MOSFETs. The MCZ33291 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.
