Product Descriptions
This driver module is designed based on the TB67H450 chip and is a PWM chopper type DC brushed motor driver. Dual channel drive, capable of achieving PWM constant current drive and direct PWM drive; Supports four working modes: forward rotation/reverse rotation/braking/stopping rotation; Built in VCC regulator for internal circuit operation.
Product Functions
Refer to the following table for the working mode:
| IN1 | IN2 | OUT1 | 0UT2 | 模式 Mode |
| L | L | OFF (Hi-Z) | OFF (Hi-Z) | 停止 Stop |
| 1毫秒后進(jìn)入待機(jī)模式 Enter standby mode after 1 millisecond | ||||
| H | L | H | L | 正向 Forward direction |
| L | H | L | H | 反向 Reverse |
| H | H | L | L | 制動(dòng)器 Brake system |
| 電流路徑:正向(0UT1-0UT2)，反向(0UT2-0UT1) Current path: forward (0UT1-0UT2), reverse (0UT2-0UT1) | ||||
Maximum output current 3A (total current of two channels)
Logical input VIN (H)/VIN (L)
VIN (H): 2.0V (minimum) to 5.5V (maximum)
VIN (L): 0V (minimum) to 0.8V (maximum)
Voltage range for VREF application: 0V to 4.0V
Motor power supply voltage (VM): DC 4.5V-50V
Output pin voltage (VO): DC 4.5V-50V
(6) After the program is successfully uploaded, you can see that the motor rotates forward and then backward.
(7) To control the motor braking, standby, and acceleration functions, please refer to the "Function Description Table" in the product parameters and write the program.
