The controller monitors the hall cycle, and switches to 180° sinusoidal commutation drive when the hall cycle reaches or exceeds about 5-Hz over four consecutive cycles. Refer to the timing charts in figures 7 and 8. Table 1. 120° commutation (Six-state) truth table (CW) HU H H H L L L HV L L H H H L HW H L L L H H UH L VH PWM L L L L PWM L PWM L L PWM WH L PWM UL VL H -------------------- PWM L L -------------------- H WL PWM PWM L H -------------------- L -------------------- H L L -------------------- PWM L H L -------------------- H PWM L PWM PWM 2) Duty control The switching duty can be controlled by forcing DC voltage with value from VSPMIN to VSPMAX to the VSP pin. When the VSP voltage is higher than VSPTST, the controller forces PC pin voltage to ground (Testing mode, maximum duty and no lead angle). The VSP pin is pulled down internally by a 200 kΩ resistor. Therefore, note the impedance when setting the VSP voltage with a resistance voltage divider. 3) Carrier frequency setting The carrier frequency setting can be freely adjusted by connecting an external resistor between the RT pin and ground. The RT pin is biased to a constant voltage, which determines the charge current to the internal capacitor. Carrier frequencies can be set within a range from about 16 kHz to 50 kHz. Refer to the formula to the right. 4) FG signal output The number of FG output pulses can be switched in accordance with the number of poles and the rotational speed of the motor. The FG signal is output from the FG pin. The 12-pulse signal is generated from the three hall signals (exclusive NOR), and the 4-pulse signal is the same as hall U signal. It is recommended to pull up FGS pin to VREG voltage when malfunctioning because of the noise. 5) Direction of motor rotation setting The direction of rotation may be switched by the CCW pin. When CCW pin is “H” or open, the motor rotates at CCW direction. When the real direction is different from the setting, the commutation mode is 120° square wave drive (no lead angle). It is recommended to pull up CCW pin to VREG voltage when malfunctioning because of the noise. FOSC [kHz] = 400 RT [kΩ] FGS No. of pulse H 12 L 4 CCW Direction H CCW L CW 6) Hall signal comparator The hall comparator provides voltage hysteresis to prevent noise malfunctions. The bias current to the hall elements should be set to the input voltage amplitude from the element, at a value higher than the minimum input voltage, VHALLMIN. We recommend connecting a ceramic capacitor with value from 100 pF to 0.01 µF, between the differential input pins of the hall comparator. Note that the bias to hall elements must be set within the common mode input voltage range VHALLCM. http://www.rohm.com © 2015 ROHM Co., Ltd. All rights reserved.

The controller doesn’t output pulse of less than TMIN (0.8µs minimum). Dead time is forcibly provided to prevent external power transistors to turn-on simultaneously in upper and lower side in driver output (for example, UH and UL) of each arm. This will not overlap the minimum time TDT (1.6µs minimum). Because of this, the maximum duty of 120° square wave drive at start up is 90% (typical). 8) Phase control setting The driving signal phase can be advanced to the hall signal for phase control. The lead angle is set by forcing DC voltage to the PC pin. The input voltage is converted digitally by a 6-bit A/D converter, in which internal VREG voltage is assumed to be full-scale, and the converted data is processed by a logic circuit. The lead angle can be set from 0° to +40° at 1° intervals, and updated fourth hall cycle of phase W falling edge. Phase control function only operates at sinusoidal commutation mode. However, the controller forces PC pin voltage to ground (no lead angle) during testing mode. The VSP offset voltage (Figure 29) is buffered to PCT pin, to connect an external resistor between PCT pin and ground. The internal bias current is determined by PCT voltage and the resistor value - VPCT / RPCT -, and mixed to PC pin. As a result, the lead angle setting is followed with the duty control voltage, and the performance of the motor can be improved. Please select the RPCT value from 50 kΩ to 200 kΩ in the range on the basis of 100 kΩ, because the PCT pin current capability is a 100 µA or less. VPCT = VSP-VSPMIN VSP VSPMIN L.A.

Phase control setting example 2 9) Overcurrent protection (OCP) circuit The over current protection circuit can be activated by connecting a low value resistor for current detection between the external output stage ground and the controller IC ground. When the RCL pin voltage reaches or surpasses the threshold value, the controller forces all the upper switching arm inputs low (UH, VH, WH = L, L, L), thus initiating the overcurrent protection operation. When the RCL pin voltage swings below the ground, it is recommended to insert a resistor - 1.5 kΩ or more - between RCL pin and current detection resistor to prevent malfunction. Since this protection circuit is not a latch type, it returns to normal operation - synchronizing with the carrier frequency - once the RCL pin voltage falls below the threshold voltage. A filter is built into the overcurrent detection circuit to prevent malfunctions, and does not activate when a short pulse of less than TRCL is present at the input. 10) Under voltage lock out (UVLO) circuit To secure the lowest power supply voltage necessary to operate the controller, and to prevent under voltage malfunctions, an UVLO circuit is built into this controller. When the power supply voltage falls to VUVL or below, the controller forces all driver outputs low. When the voltage rises to VUVH or above, the UVLO circuit ends the lock out operation and returns the chip to normal operation. The voltage monitor circuit (4.0V nominal) is built-in for the VREG voltage. Therefore, the UVLO circuit does not release operation when the VREG voltage rising is delayed behind the VCC voltage rising even if VCC voltage becomes VUVH or more. http://www.rohm.com © 2015 ROHM Co., Ltd.

At this time, the controller forces all driver outputs low. Since thermal hysteresis is provided in the TSD circuit, the chip returns to normal operation when the junction temperature falls below the preset temperature (150°C nominal). The 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 in the presence of extreme heat. Do not continue to use the IC after the TSD circuit is activated, and do not use the IC in an environment where activation of the circuit is assumed. 12) Motor lock protection (MLP) circuit When the controller detects the motor locking during fixed time of 4 seconds nominal when each edge of the hall signal doesn't input either, the controller forces all driver outputs low under a fixed time 20 seconds nominal, and self-returns to normal operation. This circuit is enabled if the voltage force to VSP is over the duty minimum voltage VSPMIN, and note that the motor cannot start up when the controller doesn’t detect the motor rotation by the minimum duty control. 13) External fault signal input pin (FIB pin, low active) The FIB pin can force all controller driver outputs low at any time. The FIB pin is pulled up to VREG internally by a 100 kΩ resistor. Therefore, an open drain output can be connected directly. It is recommended to pull up FIB pin to VREG voltage when this function is not used or malfunctioning because of the noise. 14) Hall signal wrong input detection Hall element abnormalities may cause incorrect inputs that vary from the normal logic. When all hall input signals go high or low, the hall signal wrong input detection circuit forces all driver outputs low. And when the controller detects the abnormal hall signals continuously for four times or more motor rotation, the controller forces all driver outputs low and latches the state. It is released if the duty control voltage VSP is forced to ground level once. 15) Internal voltage regulator The internal voltage regulator VREG is output for the bias of the hall element and the phase control setting. However, when using the VREG function, be aware of the IOMAX value. If a capacitor is connected to the ground in order to stabilize output, a value of 1 µF or more should be used. In this case, be sure to confirm that there is no oscillation in the output. VCC VREG R1 HUP HU HUN HV HVN HW HWN HVP HWP Controller IC Figure 6.

PC, PCT 17/20 TSZ02201-0828ABB00340-1-2 03.JUN.2016 Rev.002 Datasheet BD62014AFS Notes for Use 1) Absolute maximum ratings Devices may be destroyed when supply voltage or operating temperature exceeds the absolute maximum rating. Because the cause of this damage cannot be identified as, for example, a short circuit or an open circuit, it is important to consider circuit protection measures, such as adding fuses, if any value in excess of absolute maximum ratings is to be implemented. 2) Electrical potential at GND Keep the GND terminal to the minimum potential under any operating condition. In addition, check to determine whether there is any terminal that provides voltage below GND, including the voltage during transient phenomena. However, note that even if the voltage does not fall below GND in any other operating condition, it can still swing below GND potential when the motor generates back electromotive force at the RCL terminal. The chip layout in this product is designed to avoid this sort of electrical potential problem, but pulling excessive current may still result in malfunctions. Therefore, it is necessary to observe operation closely to conclusively confirm that there is no problem in actual operation. If there are small signal GND and high current GND, it is recommended to separate the patterns for the high current GND and the small signal GND and provide a proper grounding to the reference point of the set not to affect the voltage at the small signal GND with the change in voltage due to resistance component of pattern wiring and high current. Also for GND wiring pattern of the component externally connected, pay special attention not to cause undesirable change to it. 3) Driver outputs The high voltage semiconductor generally driven by this product is connected to the next stage via the controller. If any special mode in excess of absolute maximum ratings is to be implemented with this product or its application circuits, it is important to take physical safety measures, such as providing voltage-clamping diodes or fuses. 4) Thermal design Use a thermal design that allows sufficient margin in light of the power dissipation (Pd) in actual operating conditions. 5) Inter-pin shorts and mounting errors Take 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. Also, connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when connecting the power supply lines, such as establishing an external diode between the power supply and the IC power supply pin. 6) Operation in strong electromagnetic fields Using this product in strong electromagnetic fields may cause IC malfunctions. Take extreme caution with electromagnetic fields. 7) Testing on application boards When testing the IC on an application board, connecting a capacitor to a low impedance pin 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. 8) Regarding the input pin of the IC This monolithic IC contains P+ isolation and P substrate layers between adjacent elements, in order to keep them isolated. P-N junctions are formed at the intersection of these P layers with the N layers of other elements, creating a parasitic diode or transistor. For example, the relation between each potential is as follows: When GND > 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, as well as operating malfunctions and physical damage. Therefore, do not use methods by which parasitic diodes operate, such as applying a voltage lower than the GND (P substrate) voltage to an input pin.
