This application note introduces Fairchild's Motion-SPM Smart Power Module in Mini-DIP, a highly compact switch-mode power module with low power consumption and high reliability. It features low on-resistance power MOSFETs, an integrated high-voltage MOSFET switch and driver circuit. This makes it ideal for use in inverters, DC/DC converters and other power electronic applications.
The document describes the Fairchild AN-9035 Smart Power Module (Motion-SPM) in a Mini-DIP package, designed for low-power motor control applications such as washing machines and air conditioners. It highlights the module's compact size, high power density, and integrated protection features like under-voltage and short-circuit protection. The technology combines optimized IGBTs and FRDs with built-in HVIC and LVIC drivers to eliminate the need for opto-couplers and negative bias supplies.
The guide provides technical details on the product's design concept, including its transfer mold packaging and 3-N terminal structure for individual phase current sensing. It covers internal circuit features, interface circuit examples, protection mechanisms, bootstrap circuit selection, and thermal considerations. The note also includes ordering information and package specifications.
