RT8723 - Single-Phase Full-Wave Fan Motor Driver

Description

The RT8723 is a single-phase driver IC for fan motors.

Rotation speed is controlled by supply voltage modulation and PWM input signal.

In the supply voltage control application, the fan speed slope is adjustable by the external voltage input.

Features

  • including the standby mode, thermal shutdown, lock protection, the over-current protection and also the under-voltage protection. In standby and thermal shutdown mode, supply current is less than 100μA. The rotation frequency is generated by FG output. Features z Low Supply Current z PWM Supply Voltage Control Fan Speed z Adjustable Voltage Control Fan Speed z Smart Force Start-Up Function z Built-In Lock Protection z Built-In Thermal Shutdown z Built-In Over-Current Protection z Built-In Frequ.
