Mx1616 Motor Driver Datasheet _hot_ -

Do not rely on the "Peak Current" rating for your motor selection. If your motor draws 2A when stalled, the Mx1616 may overheat and trigger its internal thermal shutdown protection after a few seconds. Always size your driver based on the rating relative to your motor's load current.

Sometimes, late at night when other students had gone home, Mara would pick up the datasheet and read the footnotes aloud, as if the chip were a living ancestor. She would imagine the room where its designers had argued over pin spacing and protection thresholds, where someone decided the maximum current was not merely a number but a limit drawn from empathy for the parts that would be connected to the driver.

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. Do not rely on the "Peak Current" rating
