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

Notes
1. Transient capability with external 100 resistor in series with VPWR pin and supply.
2. Exceeding these limits may cause a malfunction or permanent damage to the device.
3. Exceeding the limits on SCLK, SI, CS, SFPD, or RST pins may cause permanent damage to the device.
4. With output OFF.
5. Continuous output current rating so long as maximum junction temperature is not exceeded. Operation at 125°C ambient temperature
will require maximum output current computation using package RθJA.
6. ESD data available upon request.
7. ESD1 testing is performed in accordance with the Human Body Model (CZAP = 200 pF, RZAP = 1500 ), ESD2 testing is performed in
accordance with the Machine Model (CZAP = 200pF, RZAP = 0 ).
8. Maximum output clamp energy capability at 150°C junction temperature using a single non-repetitive pulse method.
9. Maximum power dissipation at indicated junction temperature with no heat sink used.

Notes
14. SPI inputs and outputs operational. Fault status reporting may not be fully operational within this voltage range. Outputs remain
operational somewhat below this VPWR range, but RDS(ON) will increase, causing power dissipation to increase. Outputs will re-
establish their instructed state following a VPWR interruption as long as VDD remains non-interrupted.
15. This parameter is guaranteed by design, but it is not production tested.
16. Measured with the RST pin held at a logic high state. Outputs can be OFF or ON or in any combination thereof.
17. Device incorporates a power-ON reset function. For VDD less than the Undervoltage Lockout Threshold voltage, all data registers are
reset and all outputs are disabled.
18. Output Fault Detect Threshold with outputs programmed OFF. Output fault detect thresholds are the same for output opens and shorts.
19. Output OFF Open Load Detect Current is the current required to flow through the load for the purpose of detecting the existence of an
open load condition when the specific output is commanded to be OFF.
