January, 2013 Rev. 1.0 6/10 ©2013 Shaoxing Devechip Microelectronics Co., Ltd. www.sdc-semi.com Single-phase Full-wave Motor Driver SDC11168 Function Description Power Supply and Ground Lines P-GND is connected to the motor power supply system and S -GND is connected to the control circuit power supply system. These two systems should be formed from separate lines and the control system external components should be connected to S-GND. Regeneration Power Supply Stabilization Capacitor The capacitor CM provides power supply stabilization for both PWM drive and kickback absorption. A capacitor w i t h a v a l u e o f o v e r 0 . 1 μ F i s u s e d f o r C M . A l a r g e capacitor must be used when the coil inductance is large or when the coil resistance is low. Sin ce this IC adopts a technique in which switching is performed by the high side transistor and regeneration is handled by the low side transistor, the pattern connecting CM to VCC and P-GND must be as wide and as short as possible. Hall Input Lines that are as short as possible must be used to prevent noise from entering the system. The Hall sensor input circuit consists of a comparator with hysteresis (20mV). We recommend that the Hall sensor input level be at least three times this hysteresis, i.e. at least 60mV P-P PWM Oscillation Frequency Setting Capacitor If a value of 100pF is used for CP, the oscillator frequency will be f = 25kHz, and this will be the basic frequency of the PWM signal. RD Output This is an open collector output. It outputs a low le vel when the motor is turning and a high level when it is stopped. This pin must be left open if unused. FG Output This is an open collector output, and a rotation count detection function can be implemented using this FG output, which corresponds to the phase switching. This pin must be left open if unused. HB Pin This pin provides a Hall effect sensor bias constant-voltage output of 1.25V. RMI Pin Connect this pin to VTH if unused. Even if unused, the IC is set internally to operate at a 10% drive duty at the voltage corresponding to the lowest speed. (The capacitor is used to set up full-speed mode at startup.)
