Product description
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, which can drive two DC motors or a 4-wire 2-phase stepper motor at the same time. The function of forward and reverse and speed regulation, each current can reach 1.5A continuous current, the peak current can reach 2.5A, has thermal protection and can automatically recover. Product Highlights: 1. Imported original professional motor driver chip, built-in low-conductance internal resistance MOS switch tube, with minimal heat generation, no heat sink, small size, power saving, ideal for your battery power supply. (L298N is a transistor switch, which has low efficiency, high heat generation, heat dissipation, bulky volume, and the L298N on the market is extremely easy to burn out. None of the original chips are used. This product can be a perfect replacement. 2. Dual 1.5A * 2, peak current can reach 2.5A, built-in overheating protection circuit, don't be afraid of motor stalling and burning, it will recover automatically when temperature drops. (The voltage and current of 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 a 4-wire two-phase stepper motor at the same time; Module power supply voltage 2V-10V; Signal terminal input voltage 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 floating, the motor will not malfunction. Built-in overheat protection circuit (TSD) with hysteresis effect, no need to worry about motor stalling; Product size: 24.7 * 21 * 5mm (length, width, height), ultra-small size, suitable for assembly and vehicle; Mounting hole diameter: 2 mm. Weight: 5g data: INx is connected to the microcontroller IO or other signal source, and MOTOR-A and MOTOR-B are connected to the motor. DC motor drive logic truth table: Precautions: 1. The positive and negative poles of the power supply are reversed, which will definitely cause circuit damage. 2. The output is short-circuited to ground or the output terminal is short-circuited, and the motor is blocked, the chip will be thermally protected, but the chip will be burned when the voltage is close to or exceeds 10V and the peak current greatly exceeds 2.5A.
The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.
In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.
All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.
This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
