TB67H420FTG Dual/Single Motor Driver Carrier

This breakout board makes it easy to use Toshiba?s TB67H420FTG brushed DC motor driver, which can operate in either dual-channel mode for independent bidirectional control of two motors or single-channel mode for driving one motor with increased current. It has a wide operating voltage range of 10 V to 47 V and can deliver a continuous 1.7 A to each motor channel, or 3.4 A in single-channel mode. A configurable current chopping threshold allows the TB67H420 to actively limit the motor current, and it features built-in protection against under-voltage, over-current, and over-temperature conditions; This carrier board also adds 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 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 3cm x 2,54cm
• Exposed solderable ground pad below the driver IC on the bottom of the PCB

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