The TB67H420FTG Dual/Single Motor Driver Carrier breaks out the H-bridge motor driver IC onto a simple to use board. Capable of bidirectional control of up to two DC motors between 10-47V. Able to supply a continuous current of 1.7A to two seperate motors or around 3.4A to a single motor, it can also cope with peak currents of  4.5A per channel or 9A to a single motor for a few seconds. This is an excellent choice when running small or medium sized motors which run at high voltages!

Dual/Single Motor Driver Carrier Features

  • Single- or dual-channel H-bridge motor driver (can drive one or two DC motors)
  • Motor supply voltage: 10 V to 47 V
  • Output current:
    • up to 1.7 A continuous (4.5 A peak) per motor in dual-channel mode
    • up to 3.4 A continuous (9 A peak) in single-channel mode
  • Configurable current chopping actively limits motor current to 4.5 A per channel (dual) or 9 A (single) by default; can be lowered with external resistors or voltage sources
  • No separate logic supply needed; inputs are 3V- and 5V-compatible
  • Flexible input interface provides several options for control
  • Under-voltage lockout and protection against over-current/short-circuit and over-temperature
  • Open-load detection
  • Carrier board adds reverse-voltage protection up to 40 V
  • Active-low error outputs indicate over-current, over-temperature, or open-load condition
  • Compact size (1.0″ × 1.2″)
  • Exposed solderable ground pad below the driver IC on the bottom of the PCB

Pinout

TB67H420FTG Dual/Single Motor Driver Carrier

PINDefault StateDescription – dual channel mode
(HBMODE = LOW)
Description – single channel mode
(HBMODE = HIGH)
VIN10 V to 47 V board power supply input (reverse-protected up to 40 V).
GNDGround connection points for the motor and logic supplies. The control source and the motor driver must share a common ground.
VMThese pins give access to the motor power supply after the reverse-voltage protection MOSFET (see the board schematic below). They can be used to supply reverse-protected power to other components in the system. VM is generally intended as an output, but it can also be used to supply board power, and some of the VM and GND holes are spaced for the addition of an optional through-hole capacitor.
A+Motor A output +.Motor output A (connect together).
A−Motor A output −.
B+Motor B output +.Motor output B (connect together).
B−Motor B output −.
VCCRegulated 5 V output: this pin gives access to the voltage from the internal regulator of the TB67H420FTG. The regulator can only provide a few milliamps, so the VCC output should only be used for logic inputs on the board, not for powering external devices.
INA1LOWControl input for A+. PWM can be applied to this pin (typically done with PWMA high).Control input for A+ and A−. PWM can be applied to this pin (typically done with PWMA high).
INA2LOWControl input for A−. PWM can be applied to this pin (typically done with PWMA high).Control input for B+ and B−. PWM can be applied to this pin (typically done with PWMA high).
PWMALOWPWM input for channel A.PWM input.
INB1LOWControl input for B+. PWM can be applied to this pin (typically done with PWMB high).Not used.
INB2LOWControl input for B−. PWM can be applied to this pin (typically done with PWMB high).Not used.
PWMBLOWPWM input for channel B.Not used.
LO1HIGHError output 1: drives low when an over-current or over-temperature fault occurs. Otherwise, the board pulls this pin up to VCC.
LO2HIGHError output 2: drives low when an open-load or over-temperature fault occurs. Otherwise, the board pulls this pin up to VCC.
VREFACurrent chopping threshold reference for channel A.Current chopping threshold reference.
VREFBCurrent chopping threshold reference for channel B.Not used.
TBLKABLOWBlanking time configuration input (see datasheet). This input should not be changed while the board is powered.
HBMODELOWH-bridge drive mode configuration input: LOW selects dual-channel mode; HIGH selects single-channel mode. This input should not be changed while the board is powered.
