LINEAR INTEGRATED CIRCUIT

COMPLEMENTARY OUTPUT

HALL EFFECT LATCH

ꢀ

DESCRIPTION

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.

SIP-4

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.

*Pb-free plating product number: H654L

ꢀ

FEATURES

* 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.(Note1)
