This IC is intended to be used for general electronic equipment [Shutter, Mirror and Lens for Camera]. 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. Any applications other than the standard applications intended. (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 It is to be understood that our company shall not be held responsible for any damage incurred as a result of or in connection with your using the IC described in this book for any special application, unless our company agrees to your using the IC in this book for any special application. 2. Pay attention to the direction of LSI. When mounting it in the wrong direction onto the PCB (printed-circuit-board), it might smoke or ignite. 3. Pay attention in the PCB (printed-circuit-board) pattern layout in order to prevent damage due to short circuit between pins. In addition, refer to the Pin Description for the pin configuration. 4. Perform a visual inspection on the PCB before applying power, otherwise damage might happen due to problems such as a solderbridge 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. 5. Take notice in the use of this product that it might break or occasionally smoke when an abnormal state occurs such as output pinVCC short (Power supply fault), output pin-GND short (Ground fault), or output-to-output-pin short (load short) . 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. 6. When designing your equipment, comply with the range of absolute maximum rating and the guaranteed operating conditions (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. 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. Be sure to read the notes to descriptions and the usage notes in the book. 9. Due to unshielded structure of this IC, under exposure of light, function and characteristic of the product cannot be guaranteed. During normal operation or even under testing condition, please ensure that IC is not exposed to light. 10. Basically, chip surface is ground potential. Please design to ensure no contact between chip surface and metal shielding. Ver. AEB 15 AN41402A Usage Notes (continued) Notes of Power LSI 1. The protection circuit is for maintaining safety against abnormal operation. Therefore, the protection circuit should not work during normal operation. Especially for the thermal protection circuit, if the area of safe operation or the absolute maximum rating is momentarily exceeded due to output pin to VCC short (Power supply fault), or output pin to GND short (Ground fault), the LSI might be damaged before the thermal protection circuit could operate. 2. Unless specified in the product specifications, make sure that negative voltage or excessive voltage are not applied to the pins because the device might be damaged, which could happen due to negative voltage or excessive voltage generated during the ON and OFF timing when the inductive load of a motor coil or actuator coils of optical pick-up is being driven. 3. The product which has specified ASO (Area of Safe Operation) should be operated in ASO. 4. Verify the risks which might be caused by the malfunctions of external components. Ver. AEB 16 AN41402A Usage Notes (continued) Notes of This LSI 1. Make sure to power on, off, and switching under the standby mode (STBY = Low). 2. Apply voltage from a low-impedance source to VDD and VM. Connect a bypass capacitor to each as near the IC as possible. 3. In case of that the output is changed into Hi-Z (IN1A = IN1B = Low, IN2A = IN2B = Low) in the rotation of motor, due to the motor current to flow back into a power source, the supply voltage might rise. 4. If the error detection circuit is active, all outputs are fixed in Hi-Z during the specified time (470 μs ±30%). The function is for safety improvements and is not guaranteed nondestructive control. 5. Check the characteristics carefully before using this IC. Preserve sufficient margin in consideration of dispersion of external components and our ICs including not only static characteristics but transition characteristics when using this IC changing external circuit constants. 6. Prohibit mounting with solder dipping and mounting to a flexible cable. 7. The heat thermal resistance is variable due to the mounted status of this IC. To reduce the heat thermal resistance, it is recommended that the power supply and GND pins are connected to a wide metal layer as short as possible. Refer to the following figure shown an example of a wiring pattern. The heat thermal resistance value (for simulation) in case of the following wiring pattern example Rth(j-a) = 88 °C / W Condition : Glass-epoxy PWB, 50×50×0.8t (mm), 4-ply Wiring pattern example 1 A GND 2 IN1A 3 IN2A 4 VM11 5 RO1 6 PG1 B STBY IN1B IN2B VM12 FO1 IC (Top View) C VDD VPU MP BC4 BC2 VM21 RO2 D BC3 BC1 VM22 FO2 PG2 Via Wiring Ver.
