Double h-bridge stepper motor, DC motor drive module, 2 channels, forward and reverse PWM speed regulation wins L298N

2 DC motor drive modules, forward and reverse PWM speed regulation, double H bridge

  Stepping motor Mini wins L298N

Product introduction: The motor drive module is very suitable for use on battery-powered smart cars, toy cars, robots, etc. The power supply voltage is 2V~10V, and it can drive two DC motors or a 4-wire 2-phase stepper motor at the same time. The function of forward and reverse rotation and speed regulation, each current can reach 1.5A continuous current, peak current can reach 2.5A, thermal protection and automatic recovery.

        Factory direct sales, better than L298N, ideal replacement.

Product Highlights:

1. Adopt imported original professional motor driver chip, built-in low conduction internal resistance MOS switch tube, very small heat generation, no heat sink, small size, power saving, it is your ideal choice for battery power supply. (L298N is a transistor switch inside, which has low efficiency, high heat generation, heat dissipation, and bulky volume. The L298N on the market is extremely easy to burn out and does not use the original chip. This product can replace it.)

2. Dual-channel 1.5A*2, peak current can reach 2.5A, built-in overheating protection circuit, don't worry about the motor blocking and burning out, it will automatically recover after the temperature drops. (The voltage and current of the current smart cars on the market are within this range)

3. Small size, light weight, 0 standby current, ideal for your model car

Product parameters:

Dual H-bridge motor drive, can drive two DC motors or one 4-wire two-phase stepping motor at the same time;

Module power supply voltage 2V-10V;

The signal terminal input voltage is 1.8-7V;

Single-channel working current 1.5A, peak current up to 2.5A, low standby current (less than 0.1uA);

Built-in anti-common-state conduction circuit, when the input terminal is suspended, the motor will not malfunction;

Built-in overheating protection circuit (TSD) with hysteresis effect, no need to worry about motor blocking;

Product size: 24.7*21*5mm (length, width and height), ultra-small size, suitable for assembly and vehicle;

Mounting hole diameter: 2 mm.

Weight: 5g

Precautions:

1. Reverse connection of the positive and negative poles of the power supply will definitely cause circuit damage.

2. The chip will be thermally protected when the output is short-circuited to the ground or the output terminal is short-circuited, and the motor is blocked. However, the chip will be burned when the voltage is close to or exceeds 10V and the peak current exceeds 2.5A.

data:

INx is connected to MCU IO or other signal source, MOTOR-A and MOTOR-B are connected to motor.
