GENERAL DESCRIPTION
The TMI8150 is an integrated DC motor driver,
applied to 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 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 TMI8150 is QFN3x3-20,
which conforms to ROHS specifications, and
the frame is 100% lead-free.
