PT392V
Single-phase Motor Driver with 2 Modes PWM speed control
OVERVIEW
The PT392V is a variable speed DC fan motor driver IC with built-in Hall sensor. The built-in dynamic offset cancellation of pre-amplifier stage achieves optimal symmetrical magnetic sensing. The output driver provides a linear drive to eliminate switching noise. Further, the linear driving of PT392V will benefit EMI performance. This IC supports two modes of PWM speed control (Digital PWM & DC voltage) for a variety of DC brushless fan motor applications.
