PT392V-A
Single-phase Motor Driver with 2 Modes PWM speed control
OVERVIEW
The PT392V-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. Further, the linear driving of PT392V-A will benefit EMI performance. PT392V-A is also featuring with jump start protection according to ISO16750-2. This IC is an optimal solution with PWM speed control for Automotive DC brushless fan motor application.
