Abstract
Apparatuses, devices, and systems for detecting open pins are described. A controller can control at least one power stage. The controller can include a first set of interface pins, a digital communication bus and a circuit configured to switch connections between a reference voltage and the first set of interface pins. The controller can read a pin status of the at least one power stage via the digital communication bus. The pin status can indicate whether the reference voltage is detected at a second set of interface pins of the at least one power stage. The controller can, based on the pin status, detect a presence or an absence of an open pin condition between the first set of interface pins and the second set of interface pins.
