Keep the input voltage range see Fig12 in mind. Be careful not to change the Datasheer wiring pattern of any external parts, either. If change is made to the constant of an external circuit, please allow a sufficient margin considering variations of the characteristics of the Products and external components, including transient characteristics, as well as static characteristics.

However, semiconductor products can fail or malfunction at a certain rate. If the chip becomes the following temperature, coil output to the motor will be open. Before you use our Pro ducts, you are requested to care fully read this document and fully understand its contents. Do not continue to use the IC after operating this circuit or use the IC in an environment where the operation of the TSD circuit is assumed.

In principle, the reflow soldering method must be used; if flow soldering method is preferred, please consult with the ROHM representative ba6664f advance.

The formation of parasitic elements as a result of the relationships of the potentials of different pins is an inevitable result of the IC’s architecture. Otherwise bent leads may occur due to excessive stress applied when dropping of a carton.

Output will be open when the reverse rotation ba6664ffm the motor is detected. It is strongly recommended to confirm solderability before using Products of which storage time is exceeding the recommended storage time period. Want to gain comprehensive data for BAFM to optimize the supply chain include cross references, lifecycle, parametric, counterfeit risk, obsolescence management forecastsplease contact to our Tech-supports team.

Shorts between output pins or between output pins and the power supply and GND pins caused by the presence of a foreign object may result in damage to the IC.


ROHM shall not be in an y way responsible or liable for an y damages, expenses or losses incurred b y you or third parties resulting from inaccur acy or errors of or concerning such information. You agree that application notes, reference designs, and associated data and information contained in this document are presented only as guidance for Products use.

Be sure that there is no problem with each property such as emptied capacity at lower datasheeet regarding electrolytic capacitor to decide bba6664fm value. Pin name Function 1 N.

Use Products within the specified time after opening a humidity barrier bag. Depending on how the torque control reference terminal voltage, ECR is specified, there may be a case when the output current for the motor does not go up to the torque limit value. Keep the input voltage range in mind. Baking is required before using Products of which storage time is exceeding the recommended storage time period. However, damage may result if absolute maximum ratings such as applied voltage and operating temperature range are exceeded.

Please take proper caution in your manufacturing process and storage so that voltage exceeding the Products maximum rating will not be applied to Products.

BA6664FM Datasheet PDF

Our Products are designed and manufactured for application in ordinary electronic equipments such as AV equipment, OA equipment, telecommunication equipment, home electronic appliances, amusement equipment, etc. All information contained in this docume nt is current as of the issuing date and subj ect to change without any prior notice.

So, it is suitable for the slow speed rotation detection. When used in sealed area, confirm the actual ambient temperature. Please log in to request free sample. A physical safety measure such as a fuse should be implemented when ga6664fm of the IC in a special mode where the absolute maximum ratings may be exceeded is anticipated. Avoid applying power exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect dztasheet performance and reliability.


V OH [V] Circuit current: Precaution Regarding Intellectual Property Rights 1. For example, when the resistors and transistors are connected to the pins as shown in Fig. The output frequency of FG2 signal is three times higher than the FG frequency signal output. Please review product page ba66644fm for detailed information, including BAFM price, datasheets, in-stock availability, technical difficulties.

ROHM shall not be in any way responsible or liable for infringement of any intellectual property rights or other damages arising from use of such information or data.: In particular, if a transient load a large amount of load applied in a short period of time, such datasyeet pulse. b6664fm

Our Products are designed and manufactured for use under standard conditions and not under any special or extraordinary environments or conditions, as exemplified below.

It is not designed to protect the IC or guarantee its operation. Precaution for Disposition When disposing Products please dispose them properly using an authorized industry waste company. Smooth rotation characteristic performance is ensured.

Precaution for Foreign Exchange and Foreign Trade act Since our Products might fall under controlled goods prescribed by the applicable foreign exchange and foreign trade act, please consult with ROHM representative in case of export.
