SY67221 Datasheet | Silergy

General Description The SY67221 is a four half-bridge driver solution for DC brush motors, bipolar stepper motors, solenoids, or other inductive loads. The highly integrated half H-bridge driver block consists of half-H-bridge with internal logic control, gate driver, over current protection and charge pump circuit. I2C munication is also supported. The SY67221 provides plete protection functions with a fault output pin for open circuit detection (OCD), over current protection (OCP), short circuit protection (SCP), under voltage lockout (UVLO) and thermal shutdown (TSD). A low-power sleep mode is also provided. The device is packaged in a 16-pin TSSOP.
