OVERVIEW
The PL392P is a variable speed DC fan motor pre-driver IC with built-in Hall sensor. The built-in dynamic offset cancellation of pre-amplifier stage achieves optimal symmetrical magnetic sensing. The pre-driver provides the controls and driving of High/Low side power MOSFET of motor. PL392P 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.
