The exposed pad (ESOP-8) must be connected to GND for thermal dissipation.
The MX1616 (like IN1, IN2). Instead, the output pins (OA/OB) are directly driven by logic-level signals from a microcontroller. This is unusual but functional for low-side switching.
The MX1616 is typically available in an (surface mount) or DIP package. Mx1616 Motor Driver Datasheet
Based on typical technical documentation, here are the core specifications of the MX1616 IC:
MOS technology results in an internal resistance of approximately 0.4Ω, reducing heat generation. The exposed pad (ESOP-8) must be connected to
