1 / 24 page MOTOROLA SEMICONDUCTOR TECHNICAL DATA © Motorola, Inc. 2002 33291 Simplified Application Schematic Document order number: MC33291/D Rev 2, 11/2002 33291 EIGHT OUTPUT SWITCH (SPI I/O) Eight Output Switch with Serial Peripheral Interface I/O The 33291 device is an eight output, low side power switch with 8-bit serial input control. The 33291 is a versatile circuit designed for automotive applica- tions, but is well suited for other environments. The 33291 incorporates SMARTMOS technology, with CMOS logic, bipolar/MOS analog circuitry, and DMOS power MOSFETs. The 33291 interfaces directly with a microcon- troller to control various inductive or incandescent loads. The circuit’s innovative monitoring and protection features include: Very Low Standby Current, SPI Cascade Fault Reporting Capability, Internal 53 V Clamp on Each Output, Output Specific Diagnostics, Independent Shutdown of Outputs. The device is parametrically specified over an ambient temperature range of -40 °C ≤ TA ≤ 125°C and 9.0 V ≤ VPWR ≤ 16 V supply. Features: • Designed to Operate Over Wide Supply Voltages of 5.5 to 26.5 V • Interfaces to Microprocessor Using 8-Bit SPI I/O Protocol up to 3.0 MHz • 1.0 A Peak Current Outputs with Maximum RDS(on) of 1.6 Ω at TJ - 150°C • Outputs Current Limited to Accommodate In-rush Currents Associated with Switching Incandescent Loads • Output Voltages Clamped to 53 V During Inductive Switching • Maximum Sleep Current (IPWR) of 25 µA • Maximum of 4.0 mA IDD During Operation DW SUFFIX PLASTIC PACKAGE CASE 751E SOICW (16+4+4) Package Options ORDERING INFORMATION Device Temperature Range TA Package MC33291DW -40 °C to 125°C SOIC-24 MC33291DWR2 -40 °C to 125°C SOIC-24 Micro- controller CMOS Input Logic CMOS Serial Shift Registers and Latches Updrain DMOS Output Switches and Sense Circuits +VBAT GND Output 7 Output 6 Output 5 Output 4 Output 3 Output 2 Output 1 Output 0 VPWR VDD SFPD SFPD CS SCLK SI RST SO This device contains 1266 active transistors.
