Application Notes z The 11-MD152 integrates saturation voltage, constant voltage, and constant current of motor driver. The range of supply voltage of 11-MD152, VDD and VB, is from 2.7V to 5.5V. The 11-MD152 input range is defined that logic “H” is from 0.8*VDD to VDD+0.4V and logic “L” is from –0.4V to 0.2*VDD. EN1, EN2 and EN3 are mode selection pins; IN1, IN2, IN3 and IN4 are motor rotation selection pins. z Normally VB should provide enough current for output loading, thus large value of C is suggested for the terminal VB. Besides, 0.01uF~0.1uF of capacitors, Cn, are also suggested between each output channel and output channel to ground. z VC provides the reference of output level at OUT4 and OUT8. If 3*VC < VB, OUT4/OUT8 gets 3 times of VC at logic “H”. And if 3*VC > VB, OUT4/OUT8 is saturated at logic “H”. z Constant current operation of 11-MD152 provides the current, which can be approximated by the following formula (See the depiction of application circuit 1 & 2. Ra+Rb is the resistance connected from Vref to ground): I PIM = I IM = (R PIM ( R IM 2900 + 0.1 )(Ra + Rb) 3150 + 0.1)(Ra + Rb) (unit : A) (unit : A) z Before switching the mode of actuator, make sure to pull low the motor rotation selection pins. Then, switch to next mode to drive the motor. z Considering of stability of function of constant current, compensation capacitor of Cc (0.1~1uF) is suggested to connect between pin OUT1 and IM.
