The (often labeled simply as MX1616) is a dual-channel brushed DC motor driver IC designed for low-voltage, high-efficiency applications such as battery-powered toys and small robotics. It utilizes an H-bridge structure with low-resistance MOSFETs to minimize heat dissipation and voltage drop. Core Technical Specifications Operating Voltage (VM) 2.0V – 10.0V DC (Standard modules typically 2V-10V) Logic Input Voltage 1.8V – 7.0V DC (Compatible with 3.3V and 5V MCUs) Continuous Output Current 1.3A – 1.5A per channel (depending on thermal conditions) Peak Output Current Up to 2.5A – 3.0A (short duration pulses) Internal Resistance ~0.4 ohms (low on-resistance MOSFETs) Standby Current Temperature Range -40°C to +80°C Pinout and Interface Core Technical Specifications Operating Voltage (VM) 2

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).
