Manufacturer Part Number
UH378G-G04-K
Description
COMPLEMENTARY OUTPUTS HALL EFFECT LATCH IC
Manufacturer
UTC [Unisonic Technologies]
Datasheet
UH378
COMPLEMENTARY OUTPUTS
HALL EFFECT LATCH IC
built-in complementary output drivers. It’s composed of internal
temperature compensation circuit and built-in protection diode to
prevent reverse power fault. It is aimed for brush-less DC Fan.
Characteristics. The Outputs alternately switch between ON and
OFF when either the magnetic flux density is larger than threshold
B
* Widen Power Supply range from 3V ~ 20V.
* On-chip Hall sensor with excellent hysteresis.
* Build-in reverse protection diode.
* TTL and MOS IC are directly drivable by the output
* The life is semi permanent because it employs contact-less parts
