Notes on Contents

1. Block Diagrams

Some of the functional blocks, circuits, or constants in the block diagrams may be omitted or simplified for

explanatory purposes

.

2. Equivalent Circuits

The equivalent circuit diagrams may be simplified or some parts of them may be omitted for purposes.

3. Timing Charts

4. Maximum Ratings

The absolute maximum ratings of a semiconductor device are a set of specified parameter values which must

not be exceeded during operation, even for an instant.

If any of these ratings are exceeded during operation, the device electrical characteristics may be irreparably

altered and the reliability and lifetime of the device can no longer be guaranteed.

Moreover, these operations with exceeded ratings may cause breakdown, damage and/or degradation to other

equipment. Applications using the device should be designed so that each maximum rating will never be

exceeded in any operating conditions.

Before using, creating and/or producing designs, refer to and comply with the precautions and conditions set

forth in this document.

5. Application Circuits

The application circuits shown in this document are provided for reference purposes only.

Thorough

evaluation is required, especially at the mass production design stage.

Toshiba does not grant any license to any industrial property rights by providing these examples of application

circuits.

6. Test Circuits

Components in the test circuits are only used to obtain and confirm the device characteristics. These

components and circuits are not guaranteed to prevent malfunction or failure from occurring in the application

equipment.

About the handling of ICs

Install the product correctly to avoid breakdown, damage and/or degradation to the product or equipment.

About over-current protection and heat protection circuits

These protection functions are intended to guard against certain output short circuits or other abnormal

conditions with only temporary effect, and are not guaranteed to prevent the IC from being damaged.

These protection features may not be effective if the product is operated outside the guaranteed operating

ranges, and some output short circuits may result in the IC being damaged.

The overcurrent protection feature is only intended to protect the IC from a temporary short circuit.

Short circuits of longer duration may damage the IC through undue stress. The systems must be configured

so that any overcurrent condition will be eliminated as soon as possible.
