When input voltage level is low, output PWM duty is low. The voltage range of output duty changes is between OSC L voltage and OSC H voltage. When the input voltage is around OSC L (about 0.5V), rotational speed of the motor may fluctuate because of the low duty start-up function operates repeatedly. The recommend voltage is higher than 0.7V.

When the hall element output signal is small, the gradient of switching of output waveform is gentle. When it is large, the gradient of switching of output waveform is steep. Gain of 55dB (560 times) is provided between input and output, therefore enter an appropriate hall element output to IC where output waveform swings sufficiently.

In this case, place a capacitor like C1 in Fig.16. In addition, when wiring from the hall element output to IC hall input is long, noise may be loaded on wiring. In this case, place a capacitor like C2 in Fig.16. H+ H- HB C2 Hall bias current = Vhb / (RH + R1) C1 RH R1 Fig.16 Application near of hall signal www.rohm.com © 2013 ROHM Co., Ltd.

H+ PWM OUT1 OUT2 FG Fig.17 Timing chart in PWM control When the voltage input to PWM terminal applies H logic : normal operation L logic : H side output is off 4-2) DC voltage speed control Output ON duty is controlled by the input voltage to PWM terminal, comparing with internal triangular wave (OSC). PWM terminal voltage become higher, output ON duty become wide. Timing chart is shown in Fig.18. PWM voltage PWM voltage > < OSC voltage : High side output ON OSC voltage : High side output OFF OSCH voltage OSC OSCL voltage PWM OUT Output ON duty Output ON duty High Low Fig.18 DC input speed control mode Setting example 1. Output ON duty 60% on Vcc=5V. PWM setting voltage equation: Setting voltage = Voscl + { ( Vosch - Voscl ) × ( Target Duty ) / 100 } + 0.2(*1) = 0.5 + { ( 2.5 - 0.5 ) × 60 / 100 } + 0.2 = 1.9 [V] (*1 The constant of delay inside IC) 4-3) Rotational speed adjusting application OSC H and OSC L voltage is generated by dividing resistance of internal power supply (REF terminal), and the ratio of those voltage are designed to be hard to fluctuate. When the input voltage at PWM terminal is constant, the affection to change output ON duty by fluctuation of OSC H and OSC L voltage is large. However, by setting that voltage input via PWM terminal is generated by dividing resistance of REF terminal voltage, application can be made hard to be affected by voltage fluctuation of triangle wave. For an application which requires strict precision, determine a value with sufficient margin after full consideration of external constant is taken. Notice : If the resistors value is too large, output ON duty is affected with a bias current to PWM. The recommend value is less than 100kohm. www.rohm.com © 2013 ROHM Co., Ltd. All rights reserved.

When H level duty of PWM input signal is close to 0%, lock protection function does not work at input frequency is slower than 1kHz , therefore enter a frequency faster than 2kHz . 6) Low duty start up function When motor start-up from stop condition, the output is driven in output duty 50%(33kHz, max.250ms). The output duty doesn’t depend on the PWM terminal input. Even if input duty is low, the motor can be started. Timing chart at the Power ON is shown in Fig.19.

Power that can be consumed by IC begins to attenuate at certain ambient temperature. this gradient is determined by thermal resistance θja. Thermal resistance θja depends on chip size, power consumption, package ambient temperature, packaging condition, wind velocity, etc., even when the same package is used. Thermal derating curve indicates a reference value measured at a specified condition. Fig.25 shows a thermal derating curve.

If any over rated values will expect to exceed the absolute maximum ratings, consider adding circuit protection devices, such as fuses. Connecting the power supply connector backward Connecting of the power supply in reverse polarity can damage IC. Take precautions when connecting the power supply lines. An external direction diode can be added. Power supply line Back electromotive force causes regenerated current to power supply line, therefore take a measure such as placing a capacitor between power supply and GND for routing regenerated current. And fully ensure that the capacitor characteristics have no problem before determine a capacitor value. (when applying electrolytic capacitors, capacitance characteristic values are reduced at low temperatures) GND potential It is possible that the motor output terminal may deflect below GND terminal because of influence by back electromotive force of motor. The potential of GND terminal must be minimum potential in all operating conditions, except that the levels of the motor outputs terminals are under GND level by the back electromotive force of the motor coil. Also ensure that all terminals except GND and motor output terminals do not fall below GND voltage including transient characteristics. Malfunction may possibly occur depending on use condition, environment, and property of individual motor. Please make fully confirmation that no problem is found on operation of IC. Thermal design Use a thermal design that allows for a sufficient margin in light of the power dissipation(Pd) in actual operating conditions. Inter-pin shorts and mounting errors Use caution when positioning the IC for mounting on printed circuit boards. The IC may be damaged if there is any connection error or if pins are shorted together. Actions in strong electromagnetic field Use caution when using the IC in the presence of a strong electromagnetic field as doing so may cause the IC to malfunction. ASO When using the IC, set the output transistor so that it does not exceed absolute maximum rations or ASO. Thermal shut down circuit The IC incorporates a built-in thermal shutdown circuit (TSD circuit). Operation temperature is 175ºC (typ.) and has a hysteresis width of 25ºC (typ.). When IC chip temperature rises and TSD circuit works, the output terminal becomes an open state. TSD circuit is designed only to shut the IC off to prevent thermal runaway. It is not designed to protect the IC or guarantee its operation. Do not continue to use the IC after operation this circuit or use the IC in an environment where the operation of this circuit is assumed. Testing on application boards When testing the IC on an application board, connecting a capacitor to a pin with low impedance subjects the IC to stress. Always discharge capacitors after each process or step. Always turn the IC’s power supply off before connecting it to or removing it from a jig or fixture during the inspection process. Ground the IC during assembly steps as an antistatic measure. Use similar precaution when transporting or storing the IC. GND wiring pattern When using both small signal and large current GND patterns, it is recommended to isolate the two ground patterns, placing a single ground point at the ground potential of application 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. Capacitor between output and GND When a large capacitor is connected between output and GND, if Vcc is shorted with 0V or GND for some cause, it is possible that the current charged in the capacitor may flow into the output resulting in destruction. Keep the capacitor between output and GND below 100uF. IC terminal input When Vcc voltage is not applied to IC, do not apply voltage to each input terminal. When voltage above Vcc or below GND is applied to the input terminal, parasitic element is actuated due to the structure of IC. Operation of parasitic element causes mutual interference between circuits, resulting in malfunction as well as destruction in the last. Do not use in a manner where parasitic element is actuated. In use We are sure that the example of application circuit is preferable, but please check the character further more in application to a part which requires high precision. In using the unit with external circuit constant changed, consider the variation of externally equipped parts and our IC including not only static character but also transient character and allow sufficient margin in determining. www.rohm.com © 2013 ROHM Co., Ltd.
