11-MD152
Multi-Channels Motor Driver For DSC
General Specifications
The 11-MD152 is all in one actuator driver for Digital Still Camera. It contains constant
current control for M-shutter and constant voltage control for zoom DC motor. It has
multiple channels, which can apply to DSC or DV zooming Lens.
Features and Benefits
Low voltage operation (VDD Min = VB Min = 2.7V)
Low saturation voltage (Upper transistor + lower transistor residual voltage 0.25V
typically at 200mA, VDD = VB = 3V)
z
z
Low input current
Constant current control and constant voltage control
Zero standby current
Reference Voltage inside (Vref=1.23V)
Thermal shutdown protection
Thin, highly reliable package:QFN-32(4.75mmX4.75mm) ,SSOP24 and TSSOP-24

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.
