Description
The SCM1240M inverter power module (IPM) devices provide 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 V AC input voltage, and 10 to 30 A (continuous) output current. They can withstand voltages of up to 600 V (IGBT breakdown voltage). The high current SCM1240M 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 compressor motor ▪ Air conditioner fan motor ▪ Refrigerator compressor motor ▪ Washing machine main motor http://www.sanken-ele.co.jp/en/ SCM1240MDS-Rev. 5

SANKEN ELECTRIC CO., LTD. SCM1240MDS-Rev. 5 High Voltage, High Current 3-Phase Motor DriversSCM1240M ▪ To use the OCP circuit shown in the Typical Application drawing, an external shunt resistor, RS, is needed. The RS value depends on how many low-side IGBTs turn on simultaneously. ▪ To avoid malfunction, the wiring between the LS and COM pins should be as short as possible. ▪ To prevent surge destruction, put a 0.01 to 1 μF snubber capacitor, CS, in parallel with the electrolytic capacitor. ▪ To prevent surge destruction, put a 18 to 20 V Zener diode between the VCC and COM pins. ▪ To prevent surge malfunction, put a 0.01 to 0.1 μF ceramic capacitor between the VCC and COM pins and the VB and HS pins. ▪ To add an external low pass filter, place RO and CO between the A to D pin of the application controller and shunt resistor RS, ensuring that the time constant of this low pass filter is less than 0.2 μs. The internal OCP circuit has a 1.5 μs (min) filtering delay. However, the low pass filter causes an additional delay to detecting an overcurrent condition of the SCM1240M, and if the total delay exceeds 1.7 μs, permanent damage to the SCM1240M may result. ▪ To suppress noise, connect a resistor, RF, and capacitor, CF, to the ¯F¯ ¯¯O¯ x pins. Also, when an overcurrent condition is detected, the ¯F¯ ¯¯O¯ x pin goes low for 25 μs (typ) as an active low fault flag, and then returns up to its normal state. It is recommended to connect the ¯F¯ ¯¯O¯ x pin directly to an interrupt pin of the external controller, to ensure the 25 μs interval is detected. ▪ To provide the best thermal shutdown protection (TSD), it is strongly recommended that the three ¯F¯ ¯¯O¯ x pins be tied together. In this way an overtemperature event (internal temperature rise above 150°C) in any of the three phases will cause all three phases to shut down. If the ¯F¯ ¯¯O¯ x pins are not tied together, but are independently pulled up to +5 V , the TSD function for each phase shuts down only that phase. Notes for Typical Application Diagram

- Although Sanken undertakes to enhance the quality and reliability of its products, the occurrence of failure and defect of se miconductor products at a certain rate is inevitable. Users of Sanken products are requested to take, at their own risk, preventative measures including safety design of the equipment or systems against any possible injury, death, fires or damages to the society due to device failure or malfunction.
- Sanken products listed in this document are designed and intended for the use as components in general purpose electronic equ ipment or apparatus (home appliances, office equipment, telecommunication equipment, measuring equipment, etc.). When considering the use of Sanken products in the applications where higher reliability is required (transportation equipment and its control systems, traffic signal control systems or equipment, fire/crime alarm systems, various safety devices, etc.), and whenever long life expectancy is required even in general purpose electronic equipment or apparatus, please contact your nearest Sanken sales representative to discuss, prior to the use of the products herein. The use of Sanken products without the written consent of Sanken in the applications where extremely high reliability is required (aerospace equipment, nuclear power control systems, life support systems, etc.) is strictly prohibited.
- In the case that you use our semiconductor devices or design your products by using our semiconductor devices, the reliabilit y largely depends on the degree of derating to be made to the rated values. Derating may be interpreted as a case that an operation range is set by derating the load from each rated value or surge voltage or noise is considered for derating in order to assure or improve the reliability. In general, derating factors include electric stresses such as electric voltage, electric current, electric power etc., environmental stresses such as ambient temperature, humidity etc. and thermal stress caused due to self-heating of semiconductor devices. For these stresses, instantaneous values, maximum values and minimum values must be taken into consideration. In addition, it should be noted that since power devices or IC’s including power devices have large self-heating value, the degree of derating of junction temperature J) affects the reliability significantly.
- When using the products specified herein by either (i) combining other products or materials therewith or (ii) physically, ch emically or otherwise processing or treating the products, please duly consider all possible risks that may result from all such uses in advance and proceed therewith at your own responsibility.
