MCZ33291EGR2 - Freescale Semiconductor, Inc - Eight-Output Switch with Serial Peripheral Interface I



Detailed Product Description


Quick Detail:


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 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.





• 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


• 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
