IC
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,
even though a 1 M pull-up resistor is built-in at ¯
F
¯
¯¯
O
¯
pin. Note that connecting to the 5 V or 3.3 V supply without a pull-up
resistor disables the TSD function (however, low-side UVLO protection and OCP function remain active).
• To avoid malfunctions resulting from noise interference, place a 0.01 to 0.1 F ceramic capacitor (C1) between the ¯
F
¯
¯¯
O
¯
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 F).
• 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 F 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.

WARNING — These devices are designed to be operated at lethal voltages and energy levels. Circuit designs
that embody these components must conform with applicable safety requirements. Pre cau tions must be
taken to prevent accidental contact with power-line potentials. Do not connect ground ed 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 Suppliers
G746 Shin-Etsu Chemical Co., Ltd.
YG6260 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, using soldering iron
• Soldering iron should be at a distance of at least 1.5 mm from the
body (resin case) of the products
Electrostatic Discharge
• When handling the products, operator must be grounded.
Grounded wrist straps worn should have at least 1 M 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.
