1.8V to 7.0V (Compatible with 3.3V and 5V microcontrollers) Mx1616 Motor Driver Datasheet

The complete datasheet for the MX1616 (mostly in Chinese) can be obtained from several sources:

The Mx1616 is efficient, but driving 1A+ current through a tiny PCB generates heat. If you are enclosing the driver in a box with no airflow, consider soldering the module to a larger prototype board or adding a small adhesive heatsink if the load is heavy.

MX1616 vs. L298N vs. DRV8833

The SOP-16 package allows for extremely small board designs. The MX1616 uses two inputs per motor to

Troubleshooting and Common Issues

The following parameters are sourced from the MX1616H technical documentation and manufacturer summaries. 2V to 8.6V (some module variants support up to 10V). Continuous Output Current ( IOUTcap I sub cap O cap U cap T end-sub

Exceeding these values may destroy the IC.

The most common application uses an Arduino Uno (or similar) to control the Mx1616. Motor State 0 Stop/Coast (Idle) 1 0 0

Designing and implementing the Mx1616 motor driver in various applications requires careful consideration of several factors, including:

Built-in over-current protection, short-circuit protection, and thermal shutdown. Pinout and Functional Description

The is a compact, low-voltage dual H‑bridge motor driver IC. At its heart are two independent H‑bridge circuits built with integrated N‑channel and P‑channel power MOSFETs. This architecture allows the driver to control two brushed DC motors or one bipolar stepper motor directly from a microcontroller. Thanks to its all‑MOSFET design and built‑in protection features, the MX1616 is often promoted as a "mini L298" that is both more efficient and much smaller than its older bipolar counterpart.

2.0V to 10.0V DC (ideal for Li-ion, LiPo, and AA battery packs).

Excellent for battery-powered applications, with a standby current typically < 0.1μ A.
