Product Introduction
DRV8837 is an integrated motor driver solution designed for applications such as cameras, consumer products, toys, and other low-voltage or battery-powered motion control devices. It features a Sleep pin and comes with a low-power sleep mode.
Two Channel DRV8837 Feature
1. Input Voltage: 1.8V ~ 12V
2. Single H-Bridge Output Current: 1.8A
3. Built-in overcurrent protection, short-circuit protection, undervoltage lockout and overheat protection. Equipped with low-power sleep mode
4. This product integrates two chips and can drive two DC motors or two 4-wire stepper motors below 1.8A.
DRV8837 Pinout
1. Please connect the power supply, drive signals and motor circuits as shown in the figure above.
2. Please refer to the logic truth table and descriptions below. The microcontroller can control the motor operation by providing control signals.
3. The onboard LED indicator facilitates observation for users.
Note : Please check the positive and negative poles of the power supply and the voltage value. Incorrect connection will cause permanent damage to the module.
Two Channel DRV8837 Pin Description
| Pin | Description |
|---|---|
| INA1 | PWM input 1 of chip A, voltage range: -0.3 ~ 7 V |
| INA2 | PWM input 2 of chip A, voltage range: -0.3 ~ 7 V |
| INB1 | PWM input 1 of chip B, voltage range: -0.3 ~ 7 V |
| INB2 | PWM input 2 of chip B, voltage range: -0.3 ~ 7 V |
| OUTA1 | Motor drive output 1 of motor A, voltage range: -0.3 ~ 7 V |
| OUTA2 | Motor drive output 2 of motor A, voltage range: -0.3 ~ 7 V |
| OUTB1 | Motor drive output 1 of motor B, voltage range: -0.3 ~ 7 V |
| OUTB2 | Motor drive output 2 of motor B, voltage range: -0.3 ~ 7 V |
| INA1 and INA2 are the output ports of 1-channel H-bridge, which are connected to the two terminals of a DC motor. | |
| INB1 and INB2 are the output ports of the 2-channel H-bridge, which are connected to the two terminals of another external DC motor. | |
| SLEEPA | When the level is low, Chip A enters sleep mode. When the level is high, it operates normally. An internal pull-down resistor to GND is integrated, voltage range: -0.5 ~ 7 V. |
| SLEEPB | When the level is low, Chip B enters sleep mode. When the level is high, it operates normally. An internal pull-down resistor to GND is integrated, voltage range: -0.5 ~ 7 V. |
