PL392S
Single Coil Smart Motor Driver IC with PWM speed control
OVERVIEW
The PL392S 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 soft switching to eliminate switching noise. PL392S is also featuring with Lead angle adjustment to get optimal motor efficiency. This IC is an optimal solution with speed controllable by DC voltage and direct PWM input signal for brushless DC fan motor application.
