MC33880PEG 8 series switches with serial peripheral interface I/O configuration
The 33880 device is a serial peripheral interface (SPI) used for 8-bit serial input control of high/low-side switches with 8 output hardware configurations. The two outputs can be controlled directly through the application's microcontroller via pulse width modulation (PWM). The 33880 controls a variety of inductive or incandescent lamp loads directly interfaced with the microcontroller. The circuit's innovative monitoring and protection features include very low standby current, "cascadable fault reporting, 40 V output voltage clamping in the internal low-side configuration, -20 V output clamping in the internal high-side configuration, output-specific diagnostics, and independent shutdown outputs."
