The Products are datasheey subject to radiation-proof design. Use the BR pin within the permissible input range. 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. 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.

If the chip becomes the following temperature, coil output to the motor will be open.

ROHM shall not be in any way responsible or liable for any damages, expenses or losses incurred by you or third parties arising from ba6664gm use of such information. Otherwise bent leads may occur due to excessive stress applied when dropping of a carton. In principle, the reflow soldering method must be used; if flow soldering method is preferred, please consult with the ROHM representative in advance. Be careful not to change the GND wiring pattern of any external parts, either.

This product has a minimum quantity of Deceleration forward rotation H: 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. Therefore, the reverse rotation detection circuit operates, and the output is turned off and open.

Baking is required before using Products of which storage time is exceeding the recommended storage time period. No license, expressly or implied, is granted hereby under any intellectual property rights or other rights of ROHM or any third parties with respect to the information contained in this document. If the connected power supply does not have sufficient current ba666f4m capacity, regenerative current will cause the voltage on the power supply line to rise, which combined with the product and its peripheral circuitry may exceed the absolute maximum ratings.

Ground the IC during assembly steps as an antistatic measure, and use similar caution when transporting or storing the IC. Assumptions should not be made regarding the state of the IC short mode or open mode when such damage is suffered. The proper names of companies or products described in this document are trademarks or registered trademarks of ROHM, its affiliated companies or third parties. Product performance and soldered connections may deteriorate if the Products are stored in the places where: Our Products are designed and manufactured for use under standard conditions and not under any ba6664mf or extraordinary environments or conditions, as exemplified below.

So, it is suitable for the slow speed rotation detection. For example, when the resistors and transistors are connected to the pins as shown in Fig.

ROHM designs and manufactures its Products subject to strict quality control system. Documents Flashcards Grammar checker.

Output will be open when the reverse rotation of the motor is detected. However, damage may result if absolute maximum ratings such as applied voltage and operating temperature range are exceeded. You agree that application notes, reference designs, and associated data and information contained in this document are presented only as guidance for Products use. Keep the input voltage range see Fig12 in mind.

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. Quickly Enter the access of compare list to find replaceable electronic parts. Precaution for Disposition When disposing Products please dispose them properly using an authorized industry dattasheet company.

In particular, if a transient load a large amount of load applied in a short period of time, such as pulse.

Confirm that operation temperature is within the specified range described in the product specification. Precaution for Electrostatic This Product is electrostatic sensitive product, which may be damaged due to electrostatic discharge. Please take proper caution in your manufacturing process and storage so that voltage exceeding the Products maximum rating will not be applied to Products.
