SMA6851M High Voltage 3-Phase Motor Driver Features and Benefits ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ Built-in pre-drive IC MOSFET power element CMOS compatible input (5 V) High-side gate driver using bootstrap circuit or floating power supply Built-in protection circuit for controlling power supply voltage drop Built-in overtemperature detection circuit (TD) Output of fault signal during operation of protection circuits Output current 2 A Small SIP (SLA 24-pin) Description The SMA6851M 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 an input voltage of 120 VAC, and provide 2 A (continuous) output current. They can withstand voltages of up to 250 V (MOSFET breakdown voltage). The SLA6800M power package includes an IC with all of the necessary power elements (six MOSFETs), pre-driver ICs (two), and flyback diodes (six), needed to configure the main circuit of an inverter. This enables the main circuit of the inverter to be configured with fewer external components than traditional designs. Applications include residential white goods (home applications) and commercial appliance motor control: • Air conditioner fan • Refrigerator compressor • Dishwasher pump Packages: Power SIP Not to scale Leadform 2451 Leadform 2452 Functional Block Diagram VB 1 VB 2 VB3 VCC1 VBB 1 VBB 2 UVLO HIN1 HIN2 HIN3 COM1 U V W1 W2 UVLO Input Logic Low Side Driver LS 3 LS 2 LS1 Input Logic UVLO UVLO UVLO High Side Level Shift Driver VCC2 VREG LIN1 LIN2 LIN3 COM2 FO Thermal Detect 7.5V Reg.

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 to 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 in the following table: Type G746 YG6260 Suppliers Shin-Etsu Chemical Co., Ltd. Momentive Performance Materials, Inc. SC102 Dow Corning Toray Silicone Co., Ltd. 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 5 s • 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.
