Integrated DC Motor Driver: The Current Is Only 15μA In low-power Sleep Mode
The TMI8150 is an Integrated DC Motor Driver, applied to a low input voltage working system. The TMI8150 uses serial communication to control 5 channels of motors, which supports PTZ motor and IR cut filter change the motor. 1~4CH can drive 2 stepper motor of PTZ (X andY axis), X-axis and Y-axis are controlled by orthogonal SPWM and support forward and reverse rotation. 5CH control IR-cut. The current consumption can be held at quite a low level during standby or operation. In low-power sleep mode, the current is only 15μA. The package form of TMI8150 is QFN3x3-20, which conforms to ROHS specifications, and the frame is 100% lead-free.
