HALL EFFECT LATCH IC
DESCRIPTION
The UTC UH277 is a Latch-Type Hall Effect sensor with built-in
complementary output drivers. It’s designed with internal temperature
compensation circuit and built-in protection diode prevent reverse
power fault. The application is aimed for brush-less DC Fan

The UH277 Outputs operate as the Hysteresis Characteristics.
The Outputs alternately ON and OFF when either the magnetic flux
density larger than threshold B_OP or the magnetic flux density lower
than B_RP.
SIP-4
FEATURES
* Widen Power Supply range from 3V ~ 20V.
* On-chip Hall sensor with excellent hysteresis.
* Open Collector outputs had the sinking capability up to 300mA.
* Output Clamping Diodes reduce the peak output voltages during
switching.
* Build-in reverse protection diode.
*Pb-free plating product number: UH277L
