H654 Key Features

  • Operate from 3.5V ~ 20V supply voltage
  • On-chip Hall sensor with two different sensitivity and hysteresis
  • High output sinking capability up to 300mA for driving large load
  • Lower current change rate reduces the peak output voltages during
  • Build-in protecting diode for chip reversal power connecting.(Note1)
  • Pb-free plating product number: H654L

H654 Description

The UTC H654 is integrated Hall sensors with plementary output drivers designed for electronic mutation of brushless DC Fan. It posed of an on-chip Hall voltage generator, a differential amplifier, Schmitt trigger, an open-collector output on a single chip. Furthermore, an internal bandgap regulator allows temperature pensated operations and a wide operating supply range.
