Notes on Contents
1. Block Diagrams
Some of the functional blocks, circuits, or constants in the block diagram 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 explanatory
purposes.
3. Timing Charts
Timing charts may be simplified for explanatory purposes.
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 used only 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 overcurrent 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.
Counter-electromotive force
When the motor reverses or stops, counter-electromotive force in the motor may influence the current to flow
to the power source. If the power source lacks sink capability, the IC power and output pins may exceed the
rating. The counter-electromotive force of the motor varies depending on the conditions of use and the features
of the motor.
Therefore ensure that there is no damage to the IC or problem in operation, and no error in or damage to
peripheral circuits resulting from counter-electromotive force.
