STK672-080 Sanyo Semicon Device, STK672-080 Datasheet - Page 17

• Manufacturer Part Number: STK672-080
• Description: Stepping Motor Driver (Sine Wave Drive) Output Current : 2.8 A (No Heat Sink)
• Manufacturer: Sanyo Semicon Device

Notes • The above current ranges apply when the output voltage is not in the avalanche state.
• The above operating substrate temperatures (Tc) are measured when the motor is operating. Since Tc will vary depending on the ambient
temperature (Ta), the value of I
operating end product.

Specifications of any and all SANYO products described or contained herein stipulate the performance,
characteristics, and functions of the described products in the independent state, and are not guarantees
of the performance, characteristics, and functions of the described products as mounted in the customer’s
products or equipment. To verify symptoms and states that cannot be evaluated in an independent device,
the customer should always evaluate and test devices mounted in the customer’s products or equipment.
SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all
semiconductor products fail with some probability. It is possible that these probabilistic failures could
give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire,
or that could cause damage to other property. When designing equipment, adopt safety measures so
that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective
circuits and error prevention circuits for safe design, redundant design, and structural design.
In the event that any or all SANYO products (including technical data, services) described or contained
herein are controlled under any of applicable local export control laws and regulations, such products must
not be exported without obtaining the export license from the authorities concerned in accordance with the
above law.
