This document describes the EVAL2293Q demonstration board for the L2293Q push-pull four channel driver with integrated diodes. The L2293Q is designed to drive inductive loads such as DC and stepping motors, or relays and solenoids. The board implements a typical application which can be used as a reference design to drive two-phase bipolar stepper motors with currents up to 0.6 A DC, multiple DC motors and a wide range of inductive loads. Housed in a QFN 5 x 5 mm 32-lead package, the small footprint of the L2293Q makes the PCB very compact (24.5 x 24.5 mm).
The document details the EVAL2293Q demonstration board, which serves as a reference design for driving two-phase bipolar stepper motors with currents up to 0.6 A DC, as well as multiple DC motors and various inductive loads. The board utilizes the L2293Q chip, housed in a compact QFN 5 x 5 mm 32-lead package, to implement a typical application circuit.
