RT8725 Datasheet Single-phase Bldc Fan Driver

Manufacturer: Richtek

Overview: ® RT8725 Single-Phase BLDC Fan Driver IC General.

Datasheet Details

The RT8725 is a single-phase driver IC for fan motors.

Rotation speed is controlled by PWM input signal.

The RT8725 provides several protection

including standby mode, thermal shutdown, lock protection, overcurrent protection and under-voltage protection. The Builtin smart force start-up function overcomes and avoids wrong status when electrical noise occurs during startup. In the standby and thermal shutdown mode, the supply current is less than 100μA. The rotation frequency is generated by FG output. Ordering Information RT8725 Package Type QU : UDFN-8L 2x3 (U-Type) Note : Lead Plating System G : Green (Halogen Free and Pb Free).
