This catalog provides information as of November, 2003. Specifications and information herein are

subject to change without notice.

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.

No part of this publication may be reproduced or transmitted in any form or by any means, electronic or

mechanical, including photocopying and recording, or any information storage or retrieval system,

or otherwise, without the prior written permission of SANYO Electric Co., Ltd.

Any and all information described or contained herein are subject to change without notice due to

product/technology improvement, etc. When designing equipment, refer to the “Delivery Specification”

for the SANYO product that you intend to use.

Information (including circuit diagrams and circuit parameters) herein is for example only; it is not

guaranteed for volume production. SANYO believes information herein is accurate and reliable, but

no guarantees are made or implied regarding its use or any infringements of intellectual property rights

or other rights of third parties.

11. Power supply stabilization

This IC has a large output current and is driven by switching, resulting in ready oscillation of the power line. It is

therefore necessary to connect a capacitor with a sufficient capacity between the VCC pin and GND for stabilization.

When a diode is inserted in the power line to prevent breakdown due to reverse connection of power supply, the power

line is particularly readily oscillated. The larger capacity need be selected.

12. Constant of integrating amplifier parts

Arrange the integrating amplifier external parts as near as possible to IC to protect them from noise effects. Arrange

them by keeping the largest possible distance from the motor.
