Unipolar Hall Effect IC In SMD Package
Order Information
PN
OH543
Operate temperature
-40～150℃
Package 1000pcs/reel
General Description: OH543 is a switched Hall-Effect IC which is for
contactless switching applications. The device includes an on-chip Hall voltage
generator for magnetic sensing, an amplifier that amplifies the Hall voltage, a
schmitt trigger to provide switching hysteresis for noise rejection, and an
open-collector output.

Caution:
1)when installing, please minimize mechanical stress on the IC shell and leads.
2)Welding temperature should be lower than 260 ℃, less than 3 seconds.
3)IC is OC output, so a pull-up resistor connected pin 1 (power) and pin 3 (output) is
necessary.
