Motor Driver 15A DC Single (DFRobot) - DRI0042
The ultra-small DC motor driver is designed for projects with limited space, featuring the LM2575 IC to drive powerful 36V@15A motors efficiently. It includes UVLO (Under Voltage Latch-Out) for system safety and provides a 5V output for Arduino or other devices. With ESD protection on its interface, it ensures reliability. The driver accepts a voltage supply of DC 12 ~ 36V and has a voltage supply limit of 6.5 ~ 40V. It operates with control signals compatible with both 3.3V and 5V systems. The driver offers PWM speed control, with a minimum valid pulse width of 200 ns. It can handle a maximum continuous operating current of 12A (no heat sink), 15A (with simple heat sink), or 20A (with a thick heat sink/cooling system). The peak current is rated at 110A. Additionally, it has a maximum output current of 500mA at 5V and operates within a temperature range of -25 ~ 85°C. The driver has M3 mounting holes and dimensions of 55mm (Length) x 55mm (Width) x 20mm (Height), weighing 42g.
