The TMI8151 is an integrated DC motor driver, applied to low input voltage working system. The TMI8151 uses serial communication to control 5 channels of motors, which supports PTZ motor and IR cut filter change motor. 1~4CH can drive 2 stepper motor of PTZ (X and Y 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 hold at quite low level during standby or operation. In low-power sleep mode, the current is only 16μA.
The package form of TMI8151 is QFN3x3-20L, which conforms to ROHS specifications, and the frame is 100% lead-free.
