Pololu TB67H420FTG Dual/Single Motor Driver Carrier

This breakout board makes it easier to use Toshiba's TB67H420FTG DC motor driver either in dual-channel mode for independent bidirectional control of two motors or in single-channel mode for one motor with increased drive power. The breakout has a wide operating voltage range of 10 V to 47 V and can deliver a continuous 1.7 A for each motor channel or 3.4 A for a single channel. A configurable current-chopping threshold allows the TB67H420 to actively limit the motor current. Protection against undervoltage, overcurrent and overtemperature is also provided. The carrier board also offers reverse-voltage protection (up to 40 V).

Features:

• Single- or dual-channel H-bridge motor driver (can drive one or two DC motors)
• Motor supply voltage: 10 V to 47 V
• Up to 1.7 A continuous (4.5 A peak) per motor in dual-channel operation
• up to 3.4 A continuous (9 A peak) in single-channel mode
• The configurable current chopping will by default limit the active motor current to 4.5 A per channel or 9 A (single). This can be lowered with external resistors or voltage sources
• No separate logic supply required; inputs are compatible with 3 V and 5 V
• Flexible input interface offers multiple control options
• Undervoltage lockout and protection against overcurrent, short circuit and overtemperature
• Open-load detection
• Carrier board provides up to 40 V reverse-voltage protection
• Dimensions: 3 cm x 2.54 cm
• Active-low fault outputs indicate overcurrent, overtemperature or open load
• Ground contact on the underside of the PCB

Note: The motor supply capacitors are rated for 50 V. This is less than on most Pololu motor drivers, which have ICs rated for 40 V or less. Please keep this in mind if you want to push the high-voltage limit of this driver.
