    The SY21603 is a dual H-bridge motor driver solution for toys, printers, and other mechatronic applications. The SY21603 operates with a power-supply voltage range from 2.5V to 16V, and 1.5A RMS maximum output current.

    The device can drive two DC brush motors, a bipolar stepper motor, solenoids, or other inductive loads. The highly integrated H-bridge driver block consists of two H-bridges with internal logic control, gate drive, over current protection and charge pump circuit. Each H-bridge includes circuitry to regulate or limit the winding current.

    The SY21603 provides internal shutdown functions with a fault output pin are provided for over current protection, short circuit protection, under voltage lockout and thermal shutdown. A low-power sleep mode is also provided.
