Product description: TB67H453FTG QFN - single-channel brushed motor controller 44 V / 1.1 A - Pololu 4972
The TB67H453FTG controller is a high-quality system designed to precisely and efficiently control a single DC brushed motor . With a wide supply voltage range from 4.5 V to 44 V and a continuous current of 1.1 A , it is ideal for a variety of robotic and automation projects. The built-in active current regulation function prevents overloads, and reverse polarity protection increases application safety. The controller supports three control modes : phase / enable, PWM (IN / IN) and independent half-bridges, which provides flexibility of use and easy integration with microcontrollers.

Connecting the TB67H453FTG QFN engine controller.Connecting the controller
Connecting the TB67H453FTG controller is simple and intuitive. Connect the motor supply voltage to the VIN pin, and ground to GND , which must be common with the control logic. The OUT1 and OUT2 outputs are connected directly to the brush motor terminals. The EN / IN1 and PH / IN2 pins are used to control the direction and speed using PWM signals or phase / enable mode. The PMODE pin sets the controller's operating mode, while the SLEEP pin allows the device to sleep. The VREF and IMODE pins allow you to adjust the current limit, and the CS pin allows you to monitor the motor current . If an error is detected, the FAULT pin reports a warning signal that should be monitored by the microcontroller.
Driver pins
The controller has the following pins to facilitate connection and control:
- VIN: 4.5V to 44V motor power supply with reverse polarity protection
- GND: common ground for the engine and control logic
- VM: power output after reverse voltage protection, can power other system components
- OUT1, OUT2: outputs for connecting the motor
- EN/IN1, PH/IN2: phase/enable control inputs
- PMODE: control mode selection (phase / enable, PWM (IN / IN), independent half-bridges)
- SLEEP: Sleep input – low level puts the controller into power saving mode
- VREF: Voltage reference for setting current limit
- IMODE: current regulation mode (default cycle by cycle)
- FAULT: error signal output (overload, overheat, low voltage)
- CS: Analog output of motor current measurement (2.5 V/A)
