(2) recommended operating range this is the range within which it is possible to obtain roughly the expected characteristics. fo r electrical characteristics, it is those that are guaran teed under the conditions for each paramete r. even when these are within the recommended operating range, voltage and tem perature characteristics are indicated. (3) reverse connection of power supply connector there is a risk of damaging the lsi by reverse connection of t he power supply connector. for protection from reverse connection, take measures such as externally placing a diode between the power supply and the power supply pin of the lsi. (4) power supply lines in the design of the board pattern, make powe r supply and gnd line wiring low impedance. when doing so, although the digital power supply and analog po wer supply are the same potential, separate the digital power supply pattern and analog power supply pattern to deter digital noise from entering the analog power supply due to the common impedance of the wiring patterns. similarly take pattern design into acco unt for gnd lines as well. furthermore, for all power supply pins of the lsi, in conjun ction with inserting capacitors between power supply and gnd pins, when using electrolytic capacitors, determine constants upon adequately confirming that capacitance loss occurring at low temperatures is not a problem fo r various characteristics of the capacitors used. (5) gnd voltage make the potential of a gnd pin such t hat it will be the lowest potential ev en if operating below that. in addition, confirm that there are no pins for wh ich the potential becomes less than a g nd by actually including transition phenomena. (6) shorts between pins and misinstallation when installing in the set board, pay adequate attention to ori entation and placement discrepancies of the lsi. if it is installed erroneously, there is a risk of lsi damage. there also is a risk of damage if it is shorted by a foreign substance getting between pins or between a pin and a power supply or gnd. (7) operation in strong magnetic fields be careful when using the lsi in a strong magnetic field, since it may malfunction. (8) inspection in set board when inspecting the lsi in the set board, since there is a risk of stress to t he lsi when capacitors are connected to low impedance lsi pins, be sure to discharge for each process. moreover, when getting it on and off of a jig in the inspection process, always connect it after turning off t he power supply, perform the inspection, and remove it after turning off the power supply. furthermore, as countermeas ures against static electricity, use grounding in the assembly process and take appropriate care in transport and storage. (9) input pins parasitic elements inevitably are formed on an lsi struct ure due to potential relationships. because parasitic elements operate, they give rise to interference with ci rcuit operation and may be the cause of malfunctions as well as damage. accordingly, take care not to apply a lower volt age than gnd to an input pin or use the lsi in other ways such that parasitic elements operate. moreover, do not a pply a voltage to an input pin when the power supply voltage is not being applied to the lsi. furthermore, when the power supply voltage is being applied, make each input pin a voltage less than the power supply voltage as well as within the guaranteed values of electrical characteristics. (10) ground wiring pattern when there is a small signal gnd and a large current gnd, it is recommended that you separate the large current gnd pattern and small signal gnd pattern and provide single poi nt grounding at the referenc e point of the set so that voltage variation due to resistance components of the pattern wiring and large currents do not cause the small signal gnd voltage to change. take care that the gnd wiring pattern of externally attached components also does not change. (11) externally attached capacitors when using ceramic capacitors for externally attached ca pacitors, determine constants upon taking into account a lowering of the rated capacitance due to dc bias and capa citance change due to factors such as temperature. (12) thermal design perform thermal design in which there ar e adequate margins by taking into account the permissible dissipation (pd) in actual states of use. technical note 9/10 BD11600NUX www.rohm.com 2011.08 - rev. a ? 2011 rohm co., ltd. all rights reserved. power dissipation 0 0.2 0.4 0.6 0.8 1 1.2 1.4 1.6 1.8 2 2.2 2.4 0 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 ambient temperature :ta [] power dissipation :pd [w] pd=1.925w -15.4mw/ ta_max=85 fig.16 power dissipation technical note 10/10 BD11600NUX www.rohm.com 2011.08 - rev. a ? 2011 rohm co., ltd. all rights reserved. ordering part number b d 1 1 6 0 0 n u x - e 2 part no. part no. package nux:vson010x3020 packaging and forming specification e2: embossed tape and reel (unit : mm) vson010x3020 3.0 0.1 2.0 0.1 0.6max 0.02 +0.03 ? 0.02 s 0.05 s (0.12) 1pin mark +0.05 ? 0.04 2.0 0.1 2.39 0.1 0.5 0.1 0.64 0.1 0.4 0.1 1 10 5 6 c0.2 0.25 ? order quantity needs to be multiple of the minimum quantity. r1120 a www.rohm.com ? 2011 rohm co., ltd. all rights reserved. notice rohm customer support system http://www.rohm.com/contact/ thank you for your accessing to rohm product informations. more detail product informations and catalogs are available, please contact us. notes no copying or reproduction of this document, in part or in whole, is permitted without the consent of rohm co.,ltd. the content specied herein is subject to change for improvement without notice. the content specied herein is for the purpose of introducing rohm's products (hereinafter "products"). if you wish to use any such product, please be sure to refer to the specications, which can be obtained from rohm upon request. examples of application circuits, circuit constants and any other information contained herein illustrate the standard usage and operations of the products. the peripheral conditions must be taken into account when designing circuits for mass production. great care was taken in ensuring the accuracy of the information specied in this document. however, should you incur any damage arising from any inaccuracy or misprint of such information, rohm shall bear no responsibility for such damage. the technical information specied herein is intended only to show the typical functions of and examples of application circuits for the produc ts. rohm does not grant you, explicitly or implicitly, any license to use or exercise intellectual property or other rights held by rohm and other parties. rohm shall bear no responsibility whatsoever for any dispute arising from the use of such technical information. the products specied in this document are intended to be used with general-use electronic equipment or devices (such as audio visual equipment, ofce-automation equipment, commu- nication devices, electronic appliances and amusement devices). the products specied in this document are not designed to be radiation tolerant. while rohm always makes efforts to enhance the quality and reliability of its products, a product may fail or malfunction for a variety of reasons. please be sure to implement in your equipment using the products safety measures to guard against the possibility of physical injury, re or any other damage caused in the event of the failure of any product, such as derating, redundancy, re control and fail-safe designs. rohm shall bear no responsibility whatsoever for your use of any product outside of the prescribed scope or not in accordance with the instruction manual. the products are not designed or manufactured to be used with any equipment, device or system which requires an extremely high level of reliability the failure or malfunction of which may result in a direct threat to human life or create a risk of human injury (such as a medical instrument, transportation equipment, aerospace machinery, nuclear-reactor controller, fuel- controller or other safety device). rohm shall bear no responsibility in any way for use of any of the products for the above special purposes. if a product is intended to be used for any such special purpose, please contact a rohm sales representative before purchasing. if you intend to export or ship overseas any product or technology specied herein that may be controlled under the foreign exchange and the foreign trade law, you will be required to obtain a license or permit under the law. |
