Quick Detail:
Eight-Output Switch with Serial Peripheral Interface I/O
Description:
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 applications, 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 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.
Applications:
• 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 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
• Pb-Free Packaging Designated by Suffix Code EG
