Keep the input voltage range in mind. ROHM designs and manufactures its Products subject to strict quality control system. Use the Datasheft pin within the permissible input range. Before you use our Pro ducts, you are requested to care fully read this document and fully understand its contents. The following are examples of safety measures: Please take proper caution in your manufacturing process and storage so that voltage exceeding the Products maximum rating will not be applied to Products.

If change is datasehet to the constant of an external circuit, datashfet allow a sufficient margin considering variations of the characteristics of the Products and external components, including transient characteristics, as well as static characteristics.

Pin name Function 1 N. If the connected power supply does not have sufficient current absorption 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. However, semiconductor products can fail or malfunction at a certain rate.

Shorts between output pins or between output pins and the power supply and GND pins caused by the presence of a vatasheet object may result in damage to the IC. Quickly Enter the access of compare daasheet to find replaceable electronic parts.

It is recommended to implement a physical safety measure such as the insertion of a voltage clamp diode between the power supply and GND pins. Insert external diodes between the power supply and the IC’s power supply pins as well as the motor coil to protect against damage from backward connections. However, damage may result if absolute maximum ratings such as applied voltage and operating temperature range are exceeded.


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

You agree that application notes, reference designs, and associated data and information contained in this document are presented only as guidance for Products use.

BAFM – Deus Ex Silicium

A physical safety measure such as a fuse should be implemented when use of the IC in a special mode where the absolute maximum ratings may be exceeded is anticipated.

Please take special care under dry condition e. Dataaheet operation of parasitic elements can cause interference with circuit operation as well as IC malfunction and damage. For example, when the resistors and transistors are connected to the pins as shown in Fig. STMicroelectronics’ datsaheet new microcontroller product lines enhance the energy efficiency, functional integration and design flexibility of the STM32F4 basic product line high-end products to meet the technical requirements of high-performance embedded design.

Baking is required before using Products of which storage time is exceeding the recommended storage time period. V OH [V] Circuit current: Always discharge capacitors after each process or step.

The output frequency of FG2 signal is three times higher than the FG frequency signal output. Therefore, the reverse rotation detection circuit operates, and the output is turned off and open.

If the chip becomes the following temperature, coil output to the motor will be open. The recommended value is 0. Please verify and confirm characteristics of the final or mounted products in using the Products.

This document may not be reprinted datashee reproduced, in whole or in part, without prior written consent of ROHM. Product performance and soldered connections may deteriorate if the Products are stored in the places where: Output will be open when the reverse rotation of the motor is detected.
