PT395V
5V Single-phase Motor Driver with PWM speed control
OVERVIEW
The PT395V 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 PT395V will benefit EMI performance. This IC is an optimal solution with speed control for DC brushless fan motor application.
