The SY21607B is an H-bridge motor driver solution for motion-control applications. The device can drive one winding of a stepper motor or one brush DC motor. The highly integrated H-bridge driver block consists of two half-bridges with internal logic control, gate drive, over current protection and charge pump circuit. The device is packaged in SO8E package.

The SY21607B operates with a power-supply voltage range from 8V to 40V, and 3.5A maximum output current.

To be compatible with industry-standard devices, the SY21607B uses the PWM (IN/IN) input interface.

The SY21607B provides over current protection, short circuit protection, under voltage lockout and over temperature protection.
