This compact breakout board for Maxim’s MAX14870 motor driver offers a wide operating voltage range of 4.5 V to 36 V and can deliver a continuous 1.7 A (2.5 A peak) to a single brushed DC motor. It features a simple two-pin speed/direction interface and built-in protection against reverse-voltage, under-voltage, over-current, and over-temperature.

The MAX14870 from Maxim Integrated is a tiny H-bridge motor driver IC that can be used for bidirectional control of one brushed DC motor at 4.5 V to 36 V. It can supply up to about 1.7 A continuously and can tolerate peak currents up to 2.5 A for a few seconds, making it a good choice for small motors that run on a wide range of voltages. The MAX14870 is a great IC, but its small surface-mount package makes it difficult for the typical student or hobbyist to use; the breakout board makes it easy to use with standard solderless breadboards and 0.1″ perfboards. Since this board is a carrier for the MAX14870. The board ships are populated with SMD components, including the MAX14870 and a reverse battery protection circuit.

Single-channel H-bridge motor driver with shoot-through protection and internal 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 is needed; inputs are 3V- and 5V-compatible
Simple two-pin DIR/PWM interface (one pin controls direction and another controls speed)
Under-voltage lockout and protection against over-current/short-circuit and over-temperature
Carrier board adds reverse-voltage protection
Active-low fault output indicates an over-current or over-temperature condition
Surface-mount resistor can optionally be added to enable automatic current limiting
Compact size (0.6″×0.5″)
