The 33291L device is an eight-output, low-side power switch with 8bit 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. The device is parametrically specified over an ambient temperature range of -40C TA 125C and 9.0 V VPWR 16 V supply.
