The UTC
H654
is integrated Hall sensors with complementary
output drivers designed for electronic commutation of brushless DC
Fan.
It composed 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
compensated operations and a wide operating supply range. An
on-chip protection diode is implemented to prevent reverse power
fault.
When the magnetic flux density larger than threshold B
OP
, DO
will be turned on(low) and DOB be turned off(high). The output state
is held until the magnetic flux density is lower than B
RP
, and then DO
is reversal to turned off and DOB turned on.
FEAT URES
* Operate from 3.5V ~ 20V supply voltage.
* On-chip Hall sensor with two different sensitivity and hysteresis
settings.
* High output sinking capability up to 300mA for driving large load.
* Lower current change rate reduces the peak output voltages during
switching.
* Build-in protecting diode for chip reversal power connecting.
