Typical Application

Description

The SY21605 is an H-bridge motor driver solution for cameras, consumer products, toys, and other low-voltage or battery-powered 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 SY21605 operates with a power-supply voltage range from 2.5V to 16V, and 1.8A maximum output current.
To be compatible with industry-standard devices, the SY21605 use the PWM (IN/IN) input interface.
The SY21605 provides over current protection, short circuit protection, under voltage lockout and over temperature protection.
