Notes on Contents
Block Diagrams
Some functional blocks, circuits, or constants may be omitted or simplified in the block diagram for
explanatory purposes.
Equivalent Circuitry
Some parts of the equivalent circuitry may have been omitted or simplified for explanatory purposes.
Maximum Ratings
The absolute maximum ratings of a semiconductor device are a set of specified parameter values that must
not be exceeded during operation, even for an instant.
If any of these ratings are exceeded during operation, the electrical characteristics of the device may be
irreparably altered and the reliability and lifetime of the device can no longer be guaranteed.
Moreover, any exceeding of the ratings during operation may cause breakdown, damage and/or degradation in
other equipment. Applications using the device should be designed so that no maximum rating will ever be
exceeded under any operating conditions.
Before using, creating and/or producing designs, refer to and comply with the precautions and conditions set
forth in this document.
Application Examples
The application examples provided in this data sheet are provided for reference only. Thorough evaluation and
testing should be implemented when designing your application's mass production design.
In providing these application examples, Toshiba does not grant the use of any industrial property rights.
Handling of the IC
Ensure that the product is installed correctly to prevent breakdown, damage and/or degradation in the
product or equipment.
Short circuiting between output and line to ground faults may result in damage to the IC. Please exercise
precaution in designing the output line, power line and GND line so as to prevent such damage.
Be careful to insert the IC correctly. Inserting the IC the wrong way (e.g., wrong direction) may result in
damage to the IC.
Please exercise precaution in handling external components as shorting and opening such components may
cause an overcurrent, which in turn may result in power overcurrent and/or in damage to the IC.
Overcurrent and Thermal Protection
Toshiba does not guarantee that these protection functions will prevent damage to the product. These
functions are only intended as a temporary means of preventing output short circuiting and other abnormal
conditions.
If the guaranteed operating ranges of this product are exceeded, these protection functions may not function
as intended and this product might be damaged due to output short circuiting.
The overcurrent protection function is intended to protect this product from temporary short circuiting only.
Short circuiting that last for a long time may cause excessive stress and damage to this product.
