Mx1616 Motor Driver Datasheet Portable [ Popular ⚡ ]

When the community garden festival came, their booth smelled of soil and solder flux. The arm hummed, picking peat pellets and lowering them into a tray with a motion both mechanical and oddly graceful. Children clustered, eyes wide; the mayor smiled for a photo. An elderly volunteer poked the PCB and asked what that little black thing was. Mara offered the datasheet and a story.

| Pin # | Name | Type | Description | | :--- | :--- | :--- | :--- | | 1 | | Input | Enable driver (Low = driver ON; High = all outputs disabled) | | 2 | MS1 | Input | Microstep selection bit 1 (see truth table) | | 3 | MS2 | Input | Microstep selection bit 2 | | 4 | MS3 | Input | Microstep selection bit 3 (for 1/16 step) | | 5 | RST | Input | Reset active low – resets the translator to home position | | 6 | SLP | Input | Sleep mode (Low = sleep; High = normal operation) | | 7 | STP | Input | Step clock input (each rising edge advances the motor) | | 8 | DIR | Input | Direction control (High = CW, Low = CCW) | | 9 | VDD | Power | Logic supply voltage (3.3-5V) | | 10 | GND | Ground | Logic ground (must connect to system ground) | | 11 | VM | Power | Motor power supply (8-36V) | | 12 | PGND | Ground | Power ground (for motor return path) | | 13 | 1B | Output | Motor coil B – Phase 1 | | 14 | 2B | Output | Motor coil B – Phase 2 | | 15 | 2A | Output | Motor coil A – Phase 1 | | 16 | 1A | Output | Motor coil A – Phase 2 |

Note: Some datasheets show a slightly different arrangement; always check the exact pinout for your specific MX1616 variant. The key functional groups remain: power supply (VCC, GND), logic inputs (INx), and motor outputs (OUTx).

This article serves as an of the Mx1616. We will cover its pin configuration, electrical characteristics, wiring diagrams, programming logic, thermal specs, application use-cases, and troubleshooting tips.

2V – 10V DC (VDD), making it perfect for 3.7V Li-ion or 5V-9V battery packs.

The MX1616 is a highly efficient, dual-channel DC motor driver integrated circuit (IC) widely used in robotics, smart home devices, and battery-powered toys. It serves as an excellent, low-cost alternative to older drivers like the L298N, offering better efficiency and a much smaller form factor. When the community garden festival came, their booth

– the chip can withstand up to 4 kV HBM , making it resistant to handling damage during assembly.

The MX1616 is housed in a standard . It partitions power management, logic input, and high-current motor outputs symmetrically across its 16 pins. MX1616 1.5A Dual Motor Driver Module - Art of Circuits

Supports Pulse Width Modulation (PWM) on the input pins to control motor speed smoothly. Usage Notes An elderly volunteer poked the PCB and asked

void loop() // Forward at 50% speed analogWrite(IN1, 127); // if using direct PWM digitalWrite(IN2, LOW); delay(2000);

Outside, the garden rustled in a wind that smelled like rain and copper. The arm, powered down now, rested in a cradle of foam. Somewhere beneath the circuits, a datasheet slept—no longer just a sheet of numbers but a small instruction manual for care, for curiosity, and for the delicate art of making motors move without breaking things.

"You know," the volunteer said, fingers tracing the printed lines, "my father used to fix radios by reading manuals like that. He said a datasheet is like a person's instructions. Respect them and they’ll show you what they can do."

Up to 1.5A per channel (depending on thermal dissipation) Peak Output Current: 2.5A per channel (surge protection)
