OCTAL SERIAL SWITCH

(SPI Input/Output)

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. The circuit’s innovative monitoring and protection features are: very low

standby current, cascadable fault reporting, internal 65 V clamp on each

output, output specific diagnostics, and independent shutdown of outputs. The

TECHNICAL DATA

MC33298 is parametrically specified over a temperature range of – 40°C ≤ T

≤ +125°C ambient temperature and 9.0 V ≤ V

≤ 16 V supply. The

PWR

economical 20 pin DIP and SO–24 wide body surface mount plastic packages

make the MC33298 very cost effective.

• 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
