Speed control is achieved by applying a Pulse Width Modulation (PWM) signal to the driving pin while keeping the other pin LOW. This unique "direct drive" architecture is a key advantage over drivers requiring a separate enable pin, as it allows for more advanced control techniques with fewer I/O pins.
If you are designing a custom PCB or layout for the MX1616, let me know: Your exact source The stall current of your selected motors
To control speed, apply a PWM signal to the input pin designated for direction while holding the other pin low (or use PWM on both for advanced braking).
The Mx1616 requires proper heat sinking. At 1.6A continuous, the driver can reach 85ยฐC within minutes. An active cooling fan or a glued-on aluminum heat sink is strongly recommended. Mx1616 Motor Driver Datasheet
โ prevents the MOSFETs from operating when the supply voltage is too low, which could cause erratic behaviour.
Excellent for battery-powered applications, with a standby current typically < 0.1ฮผ A.

Whether you are building a line-following robot or a small RC vehicle, understanding the Mx1616 datasheet is crucial for pushing the module to its limits without damaging your hardware. This article breaks down the key specifications, pinouts, and operating parameters found in the typical Mx1616 datasheet.
Allows independent control of two DC brushed motors.

The driver typically comes in a SOP-16 package or as a pre-soldered module. It features four control inputs and four motor outputs to manage two independent DC motors or one 4-wire stepper motor. Motor Output State Standby / Coast (High Impedance) Brake (Short circuit)
The motor behavior is dictated by the logic applied to the input pins (IN1-IN4). Motor State Stop / Standby Forward (Clockwise) Reverse (Counter-Clockwise) Brake (Short) Note: The same logic applies to IN3/IN4 for Motor B. 5. Application Circuit and Usage The MX1616 module is incredibly simple to implement. Typical Connections: Connect your battery (2.0V - 8.6V) to the VDDcap V sub cap D cap D end-sub and GND terminals. Motor A: Connect Motor A terminals to OUT1 and OUT2. Motor B: Connect Motor B terminals to OUT3 and OUT4.
