11-MD127 Low-saturation, Low-voltage 2 Channels Bi-directional Motor Driver
General Specifications
The device is a two-channel low-saturation bi-directional motor driver IC. The design is optimal for 2-dc motor or stepper-motor applications, such as driving shutter/iris on cameras and other motor applications on portable devices.
Features and Benefits
Low voltage operation ( VDD min = 2.0V ) Low saturation voltage ( Upper transistor + low transistor residual voltage; 0.46V typ. at 400mA) Low input current Low operating current High output sinking and driving capability Ultra-small, thin, highly reliable package (WLCSP, MSOP-10 and DFN-10) Thermal shutdown protection

Application Notes
The power dissipated by the IC varies widely with the supply voltage, the output current, and loading. It is important to ensure the application does not exceed the allowable power dissipation of the IC package. The recommended motor driver power dissipation versus temperature is depicted as follows: Pdmax VS Ta
