MC33291DW

The MC33291DW is designed as an eight-output, low-side power switch with 8-bit serial input control. The 33291 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 33291 interfaces directly with a microcontroller to control various inductive or incandescent loads.

It has eight features. (1)Designed to operate over wide supply voltages of 5.5V to 26.5V. (2)Interfaces to microprocessor ssing 8-bit SPI I/O protocol up to 3.0MHz. (3)1.0A peak current outputs with maximum Rds(on) of 1.6 at Tj=150°C. (4)Outputs current-limited to accommodate in-rush currents associated with switching incandescent loads. (5)Output voltages clamped to 53V during inductive switching. (6)Maximum sleep current (Ipwr) of 25A. (7)Maximum of 4.0mA Idd during operation. (8)Pb-free packaging designated by suffix code EG. Thata re all the main features.

Some absolute maximum ratings have been concluded into several points as follow. (1)Its power supply voltage would be from -1.5V to 26.5V for nominal operation and would be from -13V to 60V for transient conditions. (2)Its logic supply voltage would be from -0.3V to 7.0V. (3)Its input pin voltage would be from -0.3V to 7.0V. (4)Its output clamp voltage would be from 45V to 65V. (5)Its output self-limit current woud be from 1.0A to 3.0A. (6)Its continuous per output current would be 500mA. (7)Its ESD voltage would be +/-2000V for human body mdel and would be +/-200V for machine model. (8)Its output clamp energy would be 50mJ. (9)Its recommended frequency of SPI operation would be 3.0MHz. (10)Its storage temperature range would be from -55°C to +150°C. (11)Its operating junction temperature range would be from -40°C to 150°C. (12)Its power dissipation would be 2.0W. And so on.
