Pololu MAX14870 Single Brushed DC Motor Driver Carrier

This compact carrier board for Maxim's MAX14870 motor driver offers a wide operating voltage range of 4.5 V to 36 V and can deliver 1.7 A of continuous current (2.5 A peak) to a single brushed DC motor. It features a simple two-pin interface for speed and direction, as well as built-in protection against reverse voltage, undervoltage, overcurrent, and overtemperature.

Features:

• Single H-bridge motor driver with shoot-through protection and integrated free-wheeling diodes (can drive one DC motor)
  
• Motor supply voltage: 4.5 V to 36 V
  
• Output current: up to 1.7 A continuous (2.5 A peak)
  
• No separate logic supply needed; inputs are 3V- and 5V-compatible
  
• Simple two-pin DIR/PWM interface (one pin controls direction, the other controls speed)
  
• Undervoltage lockout and protection against overcurrent, short-circuit, and overtemperature
  
• Carrier board provides reverse-voltage protection
  
• Active-low fault output indicates overcurrent or overtemperature conditions
  
• Can optionally add an SMD resistor to enable automatic current limiting
  
• Compact size (0.6″ × 0.5″)
