Pololu TB67H420FTG Dual/Single Motor Driver Carrier (1.7/3.4 A)

• Pololu TB67H420FTG Dual/Single Motor Driver Carrier
• Can drive one or two DC motors
• Output current: 1.7 A (dual-channel mode) or 3.4 A (single-channel mode)
• Motor supply voltage: 10 V to 47 V
• Requires assembly

The Pololu TB67H420FTG Dual/Single Motor Driver Carrier (1.7/3.4 A) 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; the carrier board also adds reverse-voltage protection (up to 40 V).

Features

• 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
