Freescale Semiconductor, Inc. MOTOROLA SEMICONDUCTOR TECHNICAL DATA Document order number: MC33880/D Rev 3.0, 01/2004 Advance Information Configurable Octal Serial Switch with Serial Peripheral Interface I/O The 33880 device is an eight-output hardware configurable high-side/lowside switch with 8-bit serial input control. Two of the outputs may be controlled directly via microprocessor for PWM applications. The 33880 incorporates SMARTMOS technology, with CMOS logic, bipolar/MOS analog circuitry, and DMOS power MOSFETs. The 33880 controls various inductive or incandescent loads by directly interfacing with a microcontroller.
