TMI8150B Datasheet | TOLL

FEATURES - Built-in 5-channel Motor Driver - 1~4CH Control Two Stepper Motors or Four DC Motor, and the 5CH Channel Control One DC Motor or Coil - 1CH/2CH & 3CH/4CH are Capable of Micro-steps Mode to Drive Maximum 512 Resolution Micro-steps - 2.4V to 5.5V Operating Voltage - Maximum Continuous Current: 0.7A - VM Under-voltage Lockout (UVLO) - Thermal Shutdown (TSD) - Low-power Sleep Mode - Automatic Fault Recovery - A Small 20-pin QFN Package Type Has Been Adopted APPLICATIONS - DC motor & STM motor - PTZ of IPC - Robot TYPICAL APPILCATION GENERAL DESCRIPTION The TMI8150Bis an integrated DC motor driver, applied to low input voltage working system. The TMI8150B uses serial munication 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 TMI8150B is QFN3x3-20L, which conforms to ROHS specifications, and the frame is 100% lead-free. TMI8150B_V0.5 2024 Figure 1. Application Circuit .toll-semi.
