MC33291L : 1.4 Ohm Rdson Eight Output Switch with SPI
The MC33291L is an eight output low side power switch with 8 bit
serial input control. The MC33291L is a versatile circuit designed
for automotive applications, but is well suited for other
environments. The MC33291L incorporates SMARTMOS technology, with
CMOS logic, bipolar/MOS analog circuitry, and DMOS power MOSFETs.
The MC33291L interfaces directly with a microcontroller to control
various inductive or incandescent loads.
MC33291L Features
Designed to Operate Over Wide Supply Voltages of 5.5 to 26.5 V
Interfaces Directly with Microprocessor Using 8 Bit SPI I/O
Protocol to 3.0 MHz
Outputs Current Limited to 1.0 to 3.0 A for Switching
Incandescent Loads
Output Voltages Clamped to 53 V During Inductive Switching
Open Load Detection (Outputs OFF)
Overvoltage Detection and Shutdown
