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)

Small SIP (SMA 24-pin)
The SMA6850MX/MZ 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 2.5 A (continuous)
output current. They can withstand voltages of up to 500 V
(MOSFET breakdown voltage).
The SMA6850MX/MZ power package includes an IC with all
of the necessary power elements (six MOSFETs) and pre-driver
ICs (two), 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
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.
▪ This IPM does not have an overcurrent detection feature. It is recommended to implement the feature externally. When an
overcurrent condition occurs, the application MCU must stop driving the IPM within 2 μs.
▪ Snubber capacitors should be surge suppressor film capacitors with sufficient rating to suppress surge voltavges. To determine
the capacitance for an application, please verify the surge voltage in the actual application.

1The
Thermal Detection function drives the FO pin output to logic high. The external microcontroller should detect
this condition.
2Returning to the Normal mode of operation from a V
CC UVLO condition, a low-side MOSFET resumes switching on the first
logic high of a LINx input.
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.

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:

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.

• Although Sanken undertakes to enhance the quality and reliability of its products, the occurrence of failure and defect of semiconductor 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 equipment 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 reliability 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
(TJ) affects the reliability significantly.
• When using the products specified herein by either (i) combining other products or materials therewith or (ii) physically, chemically 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.
• Anti radioactive ray design is not considered for the products listed herein.
• Sanken assumes no responsibility for any troubles, such as dropping products caused during transportation out of Sanken’s distribution network.
• The contents in this document must not be transcribed or copied without Sanken’s written consent.
