SMA6850M Series
High Voltage 3-Phase Motor Drivers
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 1.5, 2, and 2.5 A
▪ Small SIP (SMA 24-pin)
Description
TheSMA6850Minverterpowermodule(IPM)seriesprovides
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 2.5 A (continuous)
output current. They can withstand voltages of up to 500 V
(MOSFET breakdown voltage).
The SMA6850M 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.
Packages: Power SIP
Not to scale
Applications include residential white goods (home
applications) and commercial appliance motor control:
• Air conditioner fan
• Small ventilation fan
• Dishwasher pump

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.
▪ 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
thatembodythesecomponentsmustconformwithapplicablesafetyrequirements. Precautionsmustbe
takentopreventaccidentalcontactwithpower-linepotentials. Donotconnectgroundedtestequipment.
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
YG6260
SC102
Momentive Performance Materials, Inc.
Dow Corning Toray Silicone Co., Ltd.
•
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.
Soldering
•
When soldering the products, please be sure to minimize the
working time, within the following limits:
•
•
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.
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
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.
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.
Remarks About Using Silicone Grease with a Heatsink
•
•
•
Workbenches where the products are handled should be
grounded and be provided with conductive table and floor mats.
•
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.
When using measuring equipment such as a curve tracer, the
equipment should be grounded.
•
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.
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.
•
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:
•
The products should always be stored and transported in our
shipping containers or conductive containers, or be wrapped in
aluminum foil.
