RT8725
Single-Phase BLDC Fan Driver IC
General Description
The RT8725 is a single-phase driver IC for fan motors.
Rotation speed is controlled by PWM input signal.
The RT8725 provides several protection features 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.
