For engineers using the Mx1616 in SPI mode (available on some variants), the internal registers allow fine-grained control.

The Mx1616 is a dual H-bridge motor driver. An H-bridge is an electronic circuit that allows a voltage to be applied across a load in either direction. This functionality is what allows a motor to spin forward and backward.

Unlike older motor drivers like the L298N, which are bulky and inefficient due to high internal resistance, the Mx1616 utilizes modern MOSFET technology (often based on the MX1616 chip or similar architecture) to offer high efficiency and low heat dissipation in a tiny form factor.

| Input A (IN1) | Input B (IN2) | OUT1 vs OUT2 | Mode | |---------------|---------------|---------------|-----------------------| | 0 | 0 | High-Z / Floating | Coast / Standby | | 0 | 1 | OUT1 = L, OUT2 = H | Reverse (Motor CCW) | | 1 | 0 | OUT1 = H, OUT2 = L | Forward (Motor CW) | | 1 | 1 | OUT1 = L, OUT2 = L | Brake (Low-side short) | | Parameter | Symbol | Min | Max

Note: When both inputs are HIGH, both outputs are driven LOW, creating a dynamic braking condition. Avoid simultaneous high-current braking for >5 seconds without heatsinking.
