MC33298 : Octal Serial Switch with SPI

The MC33298 is an eight output low side power switch with 8 bit serial input control. The MC33298 is a versatile circuit designed for automotive applications, but is well suited for other environments. The MC33298 incorporates SMARTMOS technology, with CMOS logic, bipolar/MOS analog circuitry, and DMOS power MOSFETs. The MC33298 interfaces directly with a microcontroller to control various inductive or incandescent loads.

MC33298 Features

Designed to Operate Over Wide Supply Voltages of 5.5 V to 26.5 V

Interfaces Directly to Microprocessor Using SPI Protocol

SPI Communication for Control and Fault Reporting

8–Bit Serial I/O is CMOS Compatible

3.0 A Peak Current Outputs with Maximum R DS(on) of 0.45 W at 25°C

Outputs are Current Limited to 3.0 A to 6.0 A for Driving Incandescent Lamp Loads

Output Voltages Clamped to 65 V During Inductive Switching

Maximum Sleep Current (I PWR ) of 50 mA with V DD < 2.0 V

Maximum of 4.0 mA I DD During Operation

Maximum of 2.0 mA I PWR During Operation with All Outputs “On”
