Analog, Mixed Signal and Power Management MC33882 Six Output Low Side Switch with SPI and Parallel Input Control Applications MC33882 Simplified Application Diagram • Farm Equipment • Industrial Equipment • Fractional Horsepower DC Motor Controls • Marine Systems • Incandescent Lamp Control in Control Panels • Robotic Systems • Automotive Injectors VDD 33882 MCU Overview The MC33882 is a smart six output low side switch able to control system loads up to 1.0 A. The six outputs can be controlled via both serial peripheral interface (SPI) and parallel input control, making the device attractive for fault tolerant system applications. There are two additional 30 mA low side switches with SPI diagnostic reporting (with parallel input control only). The MC33882 is designed to interface directly with industry standard microcontrollers via SPI to control both inductive and incandescent loads. Outputs are configured as open-drain power MOSFETs incorporating internal dynamic clamping and current limiting. The device has multiple monitoring and protection features, including low standby current, fault status reporting, internal 52 V clamp on each output, outputspecific diagnostics, and protective shutdown. In addition, it has a mode select terminal affording a dual means of input control.
