Description

The MC33291LDW is designed as one member of the 33291L series which are eight-output, low-side power switches with 8-bit serial input control. It is a versatile circuit designed for automotive applications, but is well suited for other environments. MC33291LDW 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.

MC33291LDW has eight features. (1)Designed to operate over wide supply voltages of 5.5V to 26.5V. (2)Interfaces to microprocessor using 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 of 25A. (7)Maximum of 4.0mA Idd during operation. (8)Pb-free packaging designated by suffix code EG. That are all the main features.

Some absolute maximum ratings of MC33291LDW have been concluded into several points as follw. (1)Its power supply voltage would be from -1.5V to 26.5V for nominal operation and 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 would be from 1.0A to 3.0A. (6)Its continuous per output current would be from 1.0A to 3.0A. (7)Its continuous per output current would be 500mA. (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 case temperatue range would be from -40°C to 125°C. (12)Its operating junction temperature range would be from -40°C to 150°C. (13)Its power dissipation would be 2.0W. And so on. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.
