The UDN2580A-16PIN is a component from Generic, which is a 16-pin integrated circuit (IC) designed to help drivers control two-phase bipolar stepper motors. This component features a four-bit addressable latch, allowing for it to be easily interfaced with a microcontroller. It also features two inputs for controlling the speed of the motor, and two outputs for controlling the direction. This component is designed to be compatible with most standard stepper motor configurations.
