Since this drive technique is a 180 power application technique, the phase that is neither the source phase nor the sink phase does not turn completely off. Note: 1. The "H" state for FR means a voltage of 2.75 V or higher, and the "L" state means a voltage of 2.25 V or lower. (When VCC = 5 V.) 2. For the Hall inputs, the input "H" state means the state in which the (+) input for that phase is at least 0.01 V higher than the (-) input for that phase. Similarly, the "L" state means the state in which the (+) input for that phase is at least 0.01 V lower than the (-) input for that phase.

Output current detection. Current feedback is applied to the control block by inserting the resistor Rf between these pins and ground. Also, both the lower side saturation Rf(POWER) prevention circuit and the torque ripple correction circuit operate according to Rf(SENSE) the voltage on this pin. In particular, since this voltage sets the oversaturation prevention level, the lower side oversaturation prevention operation can be degraded if the value of this resistor is set too low. Note that the PWR pin and the SENSE pin must be connected together. Speed control. This circuit implements constant current drive based on current feedback from the Rf pin.

Pin Function Forward/reverse selection. The direction (forward or reverse) is selected by the voltage applied to this pin. (Vth = 2.5 Vtyp at VCC = 5 V) External torque ripple correction ratio adjustment. To adjust the correction ratio, apply the stipulated voltage to the ADJ pin from a low-impedance external circuit. If the applied voltage is increased, the correction ratio falls, and if the applied voltage is lowered, the correction ratio increases. The range of variation is from 0 to two times the correction ratio when the pin is left open. (This pin is set to about VCC/2 internally, and has an input impedance of about 5 k.) Input used when the FG amplifier inverting input is used. Connect a feedback resistor between the FGOUT pin and this pin.

Specifications of any and all SANYO products described or contained herein stipulate the performance, characteristics, and functions of the described products in the independent state, and are not guarantees of the performance, characteristics, and functions of the described products as mounted in the customer's products or equipment. To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and test devices mounted in the customer's products or equipment. SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all semiconductor products fail with some probability. It is possible that these probabilistic failures could give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire, or that could cause damage to other property. When designing equipment, adopt safety measures so that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective circuits and error prevention circuits for safe design, redundant design, and structural design. In the event that any or all SANYO products (including technical data, services) described or contained herein are controlled under any of applicable local export control laws and regulations, such products must not be exported without obtaining the export license from the authorities concerned in accordance with the above law.
