PT395V   5V Single-phase Smart DC Fan IC with 2 Modes 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. This IC is an optimal solution with PWM speed control for Automotive DC brushless fan motor application. The supply voltage range is from 2.2V to 8.0V.

FEATURE

  • Built-in high sensitivity hall sensor
  • Linear Soft switching output driver
  • Speed controllable by Digital PWM or DC voltage two modes, identified automatically
  • FG open drain output
  • Quick start
  • Protections
    • Motor locked protection and automatic restart
    • Over thermal protection
  • Built-in hysteresis comparator
  • Built-in Zener diode
  • High balance and low thermal drift magnetic sensing
  • Low power consumption and high driving efficiency
  • AEC Q100 qualified(PT395V-A only)

APPLICATIONS

    Single coils DC brushless motor
