Mx1616 Motor Driver Datasheet |link|

The MX1616 breaks out all its pins to standard 0.1" spaced headers on most modules.

Up to 1.5A / 1.6A per channel (under optimized thermal conditions) 3.0A per channel max MOSFET On-Resistance (

: A chip‑level temperature sensor continuously monitors the die temperature. When it exceeds the preset threshold (typically around 150–160°C), the driver shuts down all outputs, protecting the IC from overheating. Once the temperature falls back to a safe level (with hysteresis), the driver automatically resumes operation. Mx1616 Motor Driver Datasheet

The MX1616 is commonly found in a SOP16 package, often pre-soldered onto breakout boards. VDDcap V sub cap D cap D end-sub (Pin 5): Power Supply Input (2V - 8.6V). Ground Connection. IN1, IN2 (Pins 6, 7): Control Inputs for Motor A. IN3, IN4 (Pins 10, 11): Control Inputs for Motor B. OUT1, OUT2 (Pins 2, 3): Outputs for Motor A. OUT3, OUT4 (Pins 14, 15): Outputs for Motor B.

2.0V to 10.0V DC (ideal for Li-ion, LiPo, and AA battery packs). Once the temperature falls back to a safe

The MX1616 is typically housed in an 8-pin SOP (Small Outline Package) or DIP (Dual In-line Package). Below is the pin assignment and functional description: Pin Number Function Description OUTA1 H-Bridge A Output 1 (Connects to Motor 1 Terminal A) 2 VCC Power Supply Input for Logic and Motors (2.0V - 10.0V) 3 OUTA2 H-Bridge A Output 2 (Connects to Motor 1 Terminal B) 4 INA1 Control Input 1 for H-Bridge A 5 INA2 Control Input 2 for H-Bridge A 6 GND Ground Reference Connection 7 INB1 Control Input 1 for H-Bridge B 8 INB2 Control Input 2 for H-Bridge B 3. Control Logic and Truth Table

The MX1616H is a dual-channel motor drive circuit primarily designed for toys, smart locks, and compact robotic platforms. It consists of two full H-bridge drivers capable of controlling two brushed DC motors independently.
