PL3929-A
12V Single coil Motor Driver IC with PWM control
OVERVIEW
The PL3929-A 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 direct PWM input signal for DC brushless fan application.
