LV8162TT
Overview
Fan Motor Driver
Single-Phase Full-Wave Driver
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.
Functions
- Single-phase full-wave operating by BTL output
- Speed control available by PWM pin
- Hall bias output pin
- Built-in lock protection and automatic return circuit
- Standby mode and quick start function
- Start auxiliary function (50% futy start)
- FG (rotation speed detection) signal pin and RD (lock detection) signal pin
- Built-in thermal-shutdown (TSD)...
