5 sanken electric co., ltd. SCM1240Mds-rev. 5 high voltage, high current 3-phase motor drivers SCM1240M ? 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 f 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 f 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 s. the internal ocp circuit has a 1.5 s (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 s, 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 s (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 s 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 150c) 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

SCM1240Mds-rev. 5 high voltage, high current 3-phase motor drivers SCM1240M 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. pre cau tions must be taken to prevent accidental contact with power-line potentials. do not connect ground ed 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 (5c to 35c) 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. ? the screwing torque for attaching a heatsink shall be 58.8 to 78.4 n?cm (6.0 to 8.0 kgf?cm). ? ensure there are no foreign objects between the heatsink and thermal pad; only silicone thermal grease is allowed. remarks about using silicone grease with a heatsink ? 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 momentive performance materials holding, inc. sc102 dow corning toray silicone co., ltd. soldering ? when soldering the product, please be sure to minimize the working time, within the following limits: 2605c 10 s 3805c 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 m 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.
