Special attention and precaution in using
1. This IC is intended to be used for general electronic equipment [cam corder].
2. Pay attention to the direction of LSI. When mounting it in the wrong direction onto the PCB (printed-circuit-board), it might
3. Pay attention in the PCB (printed-circuit-board) pattern layout in order to prevent damage due to short circuit between pins.
4. Perform a visual inspection on the PCB before applying power, otherwise damage might happen due to problems such as a solder-
5. Take notice in the use of this product that it might break or occasionally smoke when an abnormal state occurs such as output pin-
6. When designing your equipment, comply with the range of absolute maximum rating and the guaranteed operating conditions
7. When using the LSI for new models, verify the safety including the long-term reliability for each product.
8. When the application system is designed by using this LSI, be sure to confirm notes in this book.
9. Pay attention not to apply any voltage and current to Pins B3(VSS), Pin C3(SUB), Pin A2(capacitor 1 for charge pump) and Pin
10. Please carry out the thermal design with sufficient margin such that the power dissipation will not be exceeded, based on the
11. For The orders of power-on and power-off, the IC does not have any restrictions on operation. For power-on, Satisfy the
Usage Notes
Consult our sales staff in advance for information on the following applications:
Special applications in which exceptional quality and reliability are required, or if the failure or malfunction of this IC may
directly jeopardize life or harm the human body.
(1) Space appliance (such as artificial satellite, and rocket)
(2) Traffic control equipment (such as for automobile, airplane, train, and ship)
(3) Medical equipment for life support
(4) Submarine transponder
(5) Control equipment for power plant
(6) Disaster prevention and security device
(7) Weapon
(8) Others : Applications of which reliability equivalent to (1) to (7) is required

In addition, refer to the Pin Description for the pin configuration.
bridge between the pins of the semiconductor device. Also, perform a full technical verification on the assembly quality, because
the same damage possibly can happen due to conductive substances, such as solder ball, that adhere to the LSI during
transportation.

And, safety measures such as an installation of fuses are recommended because the extent of the above-mentioned damage and
smoke emission will depend on the current capability of the power supply.
(operating power supply voltage and operating environment etc.). Especially, please be careful not to exceed the range of absolute
maximum rating on the transient state, such as power-on, power-off and mode-switching. Otherwise, we will not be liable for any
defect which may arise later in your equipment.
Even when the products are used within the guaranteed values, take into the consideration of incidence of break down and failure
mode, possible to occur to semiconductor products. Measures on the systems such as redundant design, arresting the spread of fire
or preventing glitch are recommended in order to prevent physical injury, fire, social damages, for example, by using the products.
Be sure to read the notes to descriptions and the usage notes in the book.
