The LV8162TT is a driver IC for single-phase fan motors that achieves low-noise operation by using BTL linear output

system. As it has a variable speed function in response to the external PWM input signal, it is best suited for driving CPU

cooling fans in notebook PCs and other applications that require low power consumption, low noise, and a variable speed

function.

• Single-phase full-wave operating by BTL output

• Hall bias output pin

• Standby mode and quick start function

• FG (rotation speed detection) signal pin and RD (lock detection) signal pin

• Built-in thermal-shutdown (TSD) circuit
