To avoid malfunctions or permanent damage to the IC, observe the following guidelines for layout of the PCB:
• W1 and W2, as well as V1 and V2 must be externally connected to each other.
• If not using the Current Limiter (OCL) function, leave the OCL and SD pins open, but the SD pin should be connected to
GND if significant external noise is observed.
• Place a pull-up resistor, RFO, between the 5 V or 3.3 V supply and the IC, selected according to anti-noise characteristics,
¯¯Ō
¯ pin. Note that connecting to the 5 V or 3.3 V supply without a pull-up
even though a 1 MΩ pull-up resistor is built-in at F̄
resistor disables the TSD function (however, low-side UVLO protection and OCP function remain active).
¯¯Ō
¯
• To avoid malfunctions resulting from noise interference, place a 0.001 to 0.01 μF ceramic capacitor (C1) between the F̄
and COM2 pins.
• To avoid malfunctions resulting from noise interference, the traces must be as short as possible between the IC and the
bootstrap capacitors, CBOOTx (≈1 μF).
• One of the bootstrap capacitors for the W phase can be populated between pin 24 (W1) and pin 25 (VB31). Also, because
pin 27 (VB32) and pin 25 are internally connected, pin 27 can be left open.
• To avoid malfunctions resulting from noise interference, place a 0.01 to 0.1 μF ceramic capacitor between the VCC1 and
COM1 (C2), as well as the VCC2 and COM2 (C3) pins. Also, the traces between them must be as short as possible.
• To avoid malfunctions resulting from noise interference, the traces between the current sense resistor RS, which is placed
between the LS and COM2 pins, and the IC must be as short and wide as possible.
• If the generated voltage on the LS pin exceeds 7 V, add a Zener diode between the LS and COM2 pins.

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 the
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
the product pins, and wrong connections. Ensure all test
parameters are within the ratings specified by Sanken for
the products.
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, using soldering iron
SX68000MH-DS
Electrostatic Discharge
• When handling the products, the operator must be
grounded. Grounded wrist straps worn should have at
least 1 MΩ of resistance from the operator to ground to
prevent shock hazard, and it should be placed near the
operator.
• 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 order to prevent
leak voltages generated by them from being applied to the
products.
• The products should always be stored and transported in
Sanken shipping containers or conductive containers, or
be wrapped in aluminum foil.

any other rights of Sanken or any third party which may result from its use.
• 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

• In the case that you use Sanken products or design your products by using Sanken products, 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 products. 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 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.
