Figure 20. PWM Input Application Application Design Note (1) The bypass capacitor connected must be more than the recommended constant value because there is a possibility of the motor start-up failure etc. due to IC malfunction. Substrate Design Note (1) IC power(Vcc), motor outputs(OUT1, 2), and motor ground lines are made as wide as possible. (2) IC ground (GND) line is common with the application ground except motor ground (i.e. hall ground etc.), and arranged near to (–) land. (3) The bypass capacitor and/or Zener diode are placed near to VCC pin. (4) H+ and H– lines are arranged side by side and made from the hall element to IC as short as possible, because it is easy for the noise to influence the hall lines. www.rohm.com © 2015 ROHM Co., Ltd.

Variable Speed Operation The rotational speed of the motor changes by the PWM duty of the motor outputs (OUT1 and OUT2 terminals). However, it provides for the motor's output not by the rotational speed but by the duty in the BD61243FV, because the rotational speed is not uniquely decided by the motor output duty. The changeable speed operation is controlled by these two input terminals. (1) PWM Operation by Pulse Input in PWM Terminal (2) PWM Operation by DC Input in MIN Terminal (Note) PWM frequency of output is 50kHz (Typ). Hence, input PWM frequency is not equal to PWM frequency of output. HALL BIAS (1) PWM Operation by Pulse Input in PWM Terminal The PWM signal from the controller can be input directly to IC in Figure 22. The output duty is controlled by the input PWM duty (Figure 23). Refer to recommended operating conditions (P.3) and electrical characteristics (P.4) for the input condition. Internal power-supply voltage (INTERNAL REG; typ 5.0V) is impressed when the PWM terminal is open, it becomes 100% input of the duty and equivalent, and a full torque is driven. There must be a pull- down resistance outside of IC to make it to torque 0 when the PWM terminal opens (However, only at the controller of the complimentary output type.). Insert the protective resistance and capacitor for noise removal if necessary.

PWM Input Application Zero Figure 23. PWM Input Operation Timing Chart Full torque (VPWM>2.5V) and zero torque( Pin A and GND > Pin B, the P-N junction operates as a parasitic diode. When GND > Pin B, the P-N junction operates as a parasitic transistor. Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should be avoided.

Example of monolithic IC structure 13. Ceramic Capacitor When using a ceramic capacitor, determine the dielectric constant considering the change of capacitance with temperature and the decrease in nominal capacitance due to DC bias and others. 14. Area of Safe Operation (ASO) Operate the IC such that the output voltage, output current, and power dissipation are all within the Area of Safe Operation (ASO). 15. Thermal Shutdown (TSD) Circuit This IC has a built-in thermal shutdown circuit that prevents heat damage to the IC. Normal operation should always be within the IC’s power dissipation rating. If however the rating is exceeded for a continued period, the junction temperature will rise which will activate the TSD circuit that will turn OFF all output pins. When the junction temperature falls below the TSD threshold, the circuits are automatically restored to normal operation. Note that the TSD circuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from heat damage. www.rohm.com © 2015 ROHM Co., Ltd.
