Description:

motor drive module is very suitable for use in the above battery-powered smart car, toy cars, robots, power supply voltage of 2V ~ 10V , can drive two DC motors or 1 Ge 4 wire 2 -phase stepping motor can be realized Reversible speed and functionality, current each way to go to 1.5A continuous current, peak current up to 2.5A , thermal protection and can be automatically restored.

Product Highlights :

• professional motor driver chip, built-in low on-resistance MOS switch, fever small, no heat sink, small size, low power consumption, is ideal for battery powered.
• (L298N internal transistor switch, low efficiency, high fever, need heat, bulky, market L298N very easy to burn, do not use the original chip, the product can be a perfect substitute.)
• Dual 1.5A * 2, the peak current to be 2.5A, built-in thermal protection circuit, do not be afraid motor stall burned, automatic recovery after the temperature dropped. ( Currently on the market of the smart car is the voltage and current are within this range )
• Small size, light weight, 0 standby current, is the ideal choice for your model of vehicle 

Product parameters:

• Dual H-bridge motor driver, can drive two DC motors or a 4-wire two-phase stepper motors;
• Module supply voltage 2V-10V;
• Signal input voltage 1.8-7V;
• Single working current 1.5A, peak current up to 2.5A, low standby current (less than 0.1uA);
• Built-in common conduction circuit, the input terminal vacant, the motor does not malfunction;
• Built-in thermal protection circuit with hysteresis effects (TSD), without worrying about motor stall;
• Size: 24.7 * 21 * 5mm (length and breadth), ultra-small size, suitable for assembly and car;
• Mounting hole diameter: 2 mm.
• Weight: 5g
• INx connected microcontroller IO or other sources, MOTOR-the A and MOTOR-B termination motors.

Precautions:

• The power supply positive and negative reversed will certainly cause damage to the circuit.
• The output is shorted to ground or output short circuit, and the motor stall, the chip will heat protection, but in the near or exceeding 10V voltage and peak current is greater than 2.5A under conditions also cause chip burned.
