OVERVIEW
The PL392F 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. Furth, the linear driving of PL392F will benefit EMI performance. PL392F is also featuring with jump start protection according to ISO16750-2. This IC is an optimal solution with speed controllable by direct PWM input signal for Automotive DC brushless fan application specifically.
