SLA6870MZ Series High Voltage 3-Phase Motor Drivers Features and Benefits ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ Description Built-in pre-drive IC MOSFET power element Alleviate noise generation by adjusting an internal resistor 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 (UVLO on VCC) Overcurrent protection (OCP), overcurrent limiting (OCL), and thermal shutdown (TSD) Output of fault signal during operation of protection circuit Output current 3 A Small SIP (SLA 24-pin) Packages: Power SIP Not to scale Leadform 2171 The SLA6870MZ inverter power module (IPM) series 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 230 VAC input voltage, and up to 3 A (continuous) output current. They can withstand voltages of up to 500 V (MOSFET breakdown voltage). The SLA6870MZ power package includes an IC with all of the necessary power elements (six MOSFETs), pre-driver ICs (two), and bootstrap diodes (three), 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 • Small ventilation fan • Dishwasher pump Leadform 2175 Functional Block Diagram VB1 VB2 VB3 UVLO UVLO UVLO VCC1 UVLO HIN1 HIN2 HIN3 Input Logic VBB High-Side Level Shift Driver COM1 W1 W2 V U SD1 VCC 2 UVLO LIN1 LIN2 LIN3 COM2 SD2 Input Logic (OCP Reset ) Thermal Shutdown Low-Side Driver OCP LS 2 OCP and OCL LS1 OCL RC Figure 1.

If these pins are not tied when an OCL condition occurs, device operation continues in Normal mode. 2Returning to the Normal mode of operation from a V CC UVLO condition, a high-side MOSFET resumes switching on the rising edge of an HINx input. On the other hand, a low-side MOSFET resumes switching on the first logic high of a LINx input after release of the UVLO condition. 3Returning to the Normal mode of operation from a V UVLO condition, a high-side MOSFET resumes switching on the rising B edge of an HINx input. Note: To prevent a shoot-through condition, the external microcontroller should not drive HINx = LINx = H at the same time.

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 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.
