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.
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
