, which minimizes heat generation compared to older bipolar-junction transistor (BJT) drivers. Standby Power: Extremely efficient standby mode drawing less than Thermal Protection: Mx1616 Motor Driver Datasheet

The Mx1616 requires proper heat sinking. At 1.6A continuous, the driver can reach 85°C within minutes. An active cooling fan or a glued-on aluminum heat sink is strongly recommended. | Symbol | Parameter | Min | Max

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.
