SCM1106M High Voltage 3 Phase Motor Driver
Features and Benefits
▪ 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 ▪ 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
Description
The SCM1106M 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 10 A (continuous) output current. They can withstand voltages of up to 600 V (IGBT breakdown voltage). 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 flyback 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

NOTE: ▪ All of the input pins are connected to GND with internal pull-down resistors rated at 100 kΩ, however, an external pull-down resistor may be required to secure stable condition of the inputs if high impedance conditions are applied to them. ▪ To use the OCP circuit, an external shunt resistor, RS, is needed. The RS value can be obtained from the formula: RS(Ω) = 0.5 V / Overcurrent Detection Set Current (A) . ▪ A blanking timer is built-in to mask the noise generated on RS at turn-on. ▪ The external electrolytic capacitors should be placed as close to the IC as possible, in order to avoid malfunctions from external noise interference. Put a ceramic capacitor in parallel with the electrolytic capacitor if further reduction of noise susceptibility is necessary.

WARNING — These devices are designed to be operated at lethal voltages and energy levels. 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 products that have 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 products from power surges from the testing device, shorts between adjacent products, and shorts to the heatsink. Remarks About Using Silicone Grease with a Heatsink • When silicone grease is used in mounting this product on a heatsink, it 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. • Our recommended silicone greases for heat radiation purposes, which will not cause any adverse effect on the product life, are indicated below: Type G746 YG6260 SC102 Suppliers Shin-Etsu Chemical Co., Ltd. GE Toshiba Silicone Co., Ltd. Dow Corning Toray Silicone Co., Ltd.
Heatsink Mounting Method Torque When Tightening Mounting Screws. The recommended tightening torque for this product package type is: 58.8 to 78.4 N•cm (6.0 to 8.0 kgf•cm). Soldering • When soldering the products, please be sure to minimize the working time, within the following limits: 260±5°C 10 s 380±5°C 5s
•
Soldering iron should be at a distance of at least 1.5 mm from the body of the products
Electrostatic Discharge • When handling the products, 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 products are 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 products, 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 products. The products should always be stored and transported in our shipping containers or conductive containers, or be wrapped in aluminum foil.
