33291L
The 33291L device is an eight-output, low-side power switch with 8-
bit serial input control. The 33291L is a versatile circuit designed for
automotive applications, but is well suited for other environments. The
33291L 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.
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, and
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 V 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 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
• Pb-Free Packaging Designated by Suffix Code EG

DEFINITION
Connection to drain of output MOSFET number seven.
Connection to drain of output MOSFET number six.
Clocks the internal Shift registers of the 33291L.
This pin is for the input of serial instruction data. SI information is read on the falling
edge of SCLK.
Connection to IC Power Ground and functions as part of heat sinking path.
Tri-stateable output from the Shift register.
Whenever this pin is in a logic low state, data can be transferred from the MCU to
the 33291L through the SI pin and from the 33291L to the MCU through the SO pin.
Connection to drain of output MOSFET number five.
Connection to drain of output MOSFET number four.
Connection to drain of output MOSFET number three.
Connection to drain of output MOSFET number two.
This pin is used to prevent the outputs from latching-OFF because of an overcurrent
condition.
Plus supply for logic.
Main power supply.
This pin is active low. It is used to clear the SPI Shift register, thereby setting all
output switches OFF.
Connection to drain of output MOSFET number one.
Connection to drain of output MOSFET number zero.
