Product Introduction
The A4950 motor driver is designed for Pulse Width Modulation (PWM) control of DC motors. Considering factors such as heat generation, the module has a current limit of 2A. It provides input terminals for controlling the speed and direction of DC motors through external PWM control signals. An internal synchronous rectification control circuit is provided to reduce power consumption during PWM operations. Internal circuit protections include overcurrent protection, motor lead-to-ground or power supply short-circuit protection, hysteretic thermal shutdown, VBB undervoltage monitoring, and cross-conduction protection.
A4950 Parameter
| Function | Can control the forward and reverse rotation of 2 motors (for example, a balance car only needs one such module), and its driving current is much larger than that of the TB6612. |
| Voltage | 7.6~30V |
| Current | The module is equipped with current limiting protection of 2A (in case of overcurrent, it will not power off, but only limit the maximum output current). |
| Control | Requires 4 PWM pins. (If reverse rotation is not required, only 2 PWM pins are needed.) It is much simpler to use than the L298. |
| Weight (including pin headers) | 3.6g |
| Size | 23.0 * 18.3 mm |
| Lead out | 2 rows of 7-pin headers |
| Pitch | 2 rows of 2.54mm pitch pin headers, with a spacing of 20mm between the two rows. |
A4950 Pin Function
| Pin | Definition |
|---|---|
| AOUT1 | Connect to the positive pole of Motor A, and control the motor by output voltage. |
| AOUT2 | Connect to the negative pole of Motor A, and control the motor by output voltage. |
| BOUT1 | Connect to the positive pole of Motor B, and control the motor by output voltage. |
| BOUT2 | Connect to the negative pole of Motor B, and control the motor by output voltage. |
| AIN1 | Motor A PWM Input 1 |
| AIN2 | Motor A PWM Input 2 |
| BIN1 | Motor B PWM Input 1 |
| BIN2 | Motor B PWM Input 2 |
| VM | Positive pole of the motor drive power supply, input according to the motor parameters, with a range of 7.6~30V. |
| VCC | Connect to 5V input. Do not input 3.3V, otherwise it will affect the performance. |
| GND | Grounding |
Precautions for the Use of A4950 Module
1. When placing the product, due to the fact that some soldered components are individually protruding in height, do not place other heavy objects on top of it to prevent damage to the surface-mount components on the circuit board, which may further affect the board’s performance.
2. The storage temperature of the circuit board should not exceed 55℃, and the humidity should be less than 60%.
3. Do not place the board near damp areas to prevent moisture damage that may affect its use. If the board gets damp, place it in a well-ventilated and dry area for drying treatment, such as under an air conditioner, using the hot air from the air conditioner for drying.
4. Since the pins of the board are exposed, do not touch the relevant pins with your hands to prevent electrostatic damage to the chip pins, which may affect the board’s performance.
5. Before using the circuit board, it is necessary to check whether the connected power supply is within the range specified in the manual to prevent breakdown of key chips due to excessively high voltage, which may affect the board’s performance.
6. When using the circuit board, be careful not to reverse the power supply connection.
A4950 Application Scenario
1. Small robot mobile platform (wheeled/track-driven)
2. Conveyor belts in automated equipment
3. Axis drive for 3D printers and CNC engraving machines
4. Smart car and aircraft model servo replacement drive
5. Controllable moving components of industrial instruments
