During operating mode, PS pin should be High-level. (See the Electrical Characteristics; p.2/9) 2) Control input (1) INA and INB pin (BD65491FV) IN1A, IN1B, IN2A and IN2B pin (BD65492MUV) These pins are used to program and control the motor drive modes. (See the Electrical Characteristics; p.2/9, and I/O Truth Table; p.7/9) (2) PWM pin When the High-level voltage is applied to the PWMEN pin (PWM pin), the I/O logic can be set to EN/IN mode. However, when the Low-level voltage is applied, the I/O logic can be set to IN/IN mode. (See the Electrical Characteristics; p.2/9, and I/O Truth Table; p.7/9) (3) TR1 and TR2 pin (BD65491FV) These pins are used to control the turn on time and turn off time for H-bridge transistors. (See the Electrical Characteristics; p.2/9, and I/O Truth Table; p.7/9) 3) VM pins The 2-channel H-bridges (BD65492MUV) can be controlled independently. But control two motors at same voltage, because each VM pin is internally short-circuited.

All rights reserved. 7/9 2011.02 - Rev.A Technical Note BD65491FV,BD65492MUV ●Notes for use 1) Absolute maximum ratings Use of the IC in excess of absolute maximum ratings such as the applied voltage or operating temperature range (Topr) may result in IC damage. Assumptions should not be made regarding the state of the IC (short mode or open mode) when such damage is suffered. The implementation of a physical safety measure such as a fuse should be considered when use of the IC in a special mode where the absolute maximum ratings may be exceeded is anticipated. 2) Power supply pins and lines None of the VM line for the H-bridge is internally connected to the VCC power supply line, which is only for the control logic or analog circuit. Therefore, the VM and VCC lines can be driven at different voltages. Although these lines can be connected to a common power supply, do not open the power supply pin but connect it to the power supply externally. Regenerated current may flow as a result of the motor's back electromotive force. Insert capacitors between the power supply and ground pins to serve as a route for regenerated current. Determine the capacitance in full consideration of all the characteristics of the electrolytic capacitor, because the electrolytic capacitor may loose some capacitance at low temperatures. 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. It is recommended to implement a physical safety measure such as the insertion of a voltage clamp diode between the power supply and ground pins. For this IC with 2 power supplies and a part consists of the CMOS block, it is possible that rush current may flow instantaneously due to the internal powering sequence and delays, and to the unstable internal logic, respectively. Therefore, give special consideration to power coupling capacitance, width of power and ground wirings, and routing of wiring. 3) Ground pins and lines Ensure a minimum GND pin potential in all operating conditions. Make sure that no pins are at a voltage below the GND at any time, regardless of whether it is a transient signal or not. When using both small signal GND and large current PGND patterns, it is recommended to isolate the two ground patterns, placing a single ground point at the application's reference point so that the pattern wiring resistance and voltage variations caused by large currents do not cause variations in the small signal ground voltage. Be careful not to change the GND wiring pattern of any external components, either. The power supply and ground lines must be as short and thick as possible to reduce line impedance. 4) Thermal design Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating conditions. 5) Actions in strong magnetic field Use caution when using the IC in the presence of a strong magnetic field as doing so may cause the IC to malfunction. 6) ASO When using the IC, set the output transistor for the motor so that it does not exceed absolute maximum ratings or ASO. 7) Thermal shutdown circuit This IC incorporates a TSD (thermal shutdown) circuit. If the temperature of the chip reaches the following temperature, the motor coil output will be opened. The TSD circuit is designed only to shut the IC off to prevent runaway thermal operation. It is not designed to protect the IC or guarantee its operation. Do not continue to use the IC after operating this circuit or use the IC in an environment where the operation of this circuit is assumed. TSD ON temperature [℃] (Typ.) Hysteresis temperature [℃] (Typ.) 175 20 8) N.C. PIN Always keep N.C. pins open. 9) Thermal PAD Connect the Thermal PAD with a small signal GND terminal. 10) Application example The application circuit is recommended for use. Make sure to confirm the adequacy of the characteristics. When using the circuit with changes to the external circuit constants, make sure to leave an adequate margin for external components including static and transitional characteristics as well as dispersion of the IC.
