OVERVIEW
The PL393V 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. This IC is an optimal solution with speed controllable by PWM input signal for DC brushless fan application. The supply voltage range is from 4.5V to 30V.
