SCM1103M High Voltage 3-Phase Motor Driver Features and Benefits Description ▪ Each half-bridge circuit consists of a pre-driver circuit that is completely independent from the others ▪ Protection against simultaneous high- and low-side turning on ▪ Bootstrap diodes with series resistors for suppressing inrush current are incorporated ▪ CMOS compatible input (3.3 to 5 V) ▪ Designed to minimize simultaneous current through both high- and low-side IGBTs by optimizing gate drive resistors ▪ Integrated Fast Recovery Diode (FRD) as freewheeling diode for each IGBT ▪ UVLO protection with auto restart ▪ Overcurrent protection with off-time period adjustable by an external capacitor ▪ Fault (FO indicator) signal output at protection activation: UVLO (low side only), OCP, and STP ▪ Proprietary power DIP package ▪ UL Recognized Component (File No.: E118037) The SCM1103M inverter power module (IPM) device provides a robust, highly-integrated solution for optimally controlling 3-phase motor power inverter systems and variable speed control systems used in energy-conserving designs to drive motors of residential and commercial appliances. These ICs take 85 to 253 VAC input voltage, and 5 A (continuous) output current. They can withstand voltages of up to 600 V (IGBT breakdown voltage). Package: Power DIP The SCM1100M series employs a new, small-footprint proprietary DIP package. The IC itself consists of all of the necessary power elements (six IGBTs), pre-drive ICs (three), and freewheeling diodes (six), needed to configure the main circuit of an inverter, as well as a bootstrap circuit (three bootstrap diodes and three boot resistors) as a high-side drive power supply. This enables the main circuit of the inverter to be configured with fewer external components than traditional designs. Applications include residential white goods (home appliances) and commercial appliance motor control, such as: ▪ Air conditioner fan motor ▪ Refrigerator compressor motor ▪ Washing machine main motor ▪ Air conditioner compressor motor Not to scale Functional Block Diagram HS VB VBB HO UV VCC Input Detect HIN Logic Level LIN & Shift Drive Circuit U, V, or W Shoot Through Prevention UV Detect COM FO O .C .

Circuit designs that embody these components must conform with applicable safety requirements. Precautions must be taken to prevent accidental contact with power-line potentials. Do not connect grounded test equipment. The use of an isolation transformer is recommended during circuit development and breadboarding. Because reliability can be affected adversely by improper storage environments and handling methods, please observe the following cautions. Cautions for Storage • Ensure that storage conditions comply with the standard temperature (5°C to 35°C) and the standard relative humidity (around 40 to 75%); avoid storage locations that experience extreme changes in temperature or humidity. • Avoid locations where dust or harmful gases are present and avoid direct sunlight. • Reinspect for rust on leads and solderability of product that has been stored for a long time. Cautions for Testing and Handling When tests are carried out during inspection testing and other standard test periods, protect the product from power surges from the testing device, shorts between adjacent product packages, and shorts to the heatsink. Remarks About Using Silicone Grease with a Heatsink • Ensure there are no foreign objects between the heatsink and thermal pad; only silicone thermal grease is allowed. • When silicone grease is used in mounting this product with a heatsink, grease shall be applied evenly and thinly. If more silicone grease than required is applied, it may produce stress. • Volatile-type silicone greases may permeate the product and produce cracks after long periods of time, resulting in reduced heat radiation effect, and possibly shortening the lifetime of the product. • Hard silicone greases may cause cracks in the product when screwing the product to a heatsink. • Our recommended silicone greases for heat radiation purposes, which will not cause any adverse effect on the product life, are indicated below: Type Suppliers G746 Shin-Etsu Chemical Co., Ltd. YG6260 SC102 Momentive Performance Materials Dow Corning Toray Silicone Co., Ltd. Soldering • When soldering the product, please be sure to minimize the working time, within the following limits: 260±5°C 10 s 380±5°C 5 s • Soldering iron should be at a distance of at least 1.5 mm from the body of the product Electrostatic Discharge • When handling the product, operator must be grounded. Grounded wrist straps worn should have at least 1 MΩ of resistance to ground to prevent shock hazard. • Workbenches where the product is handled should be grounded and be provided with conductive table and floor mats. • When using measuring equipment such as a curve tracer, the equipment should be grounded. • When soldering the product, the head of soldering irons or the solder bath must be grounded in other to prevent leak voltages generated by them from being applied to the product. • The product should always be stored and transported in our shipping containers or conductive containers, or be wrapped in aluminum foil.
