Description

• SL1603 is a Honeywell switch sensor with low power consumption, which is specially designed for systems with compact spaces and that with sensitive electric quantity in batteries. 

• The chip can provide various magnetic field threshold values,switching working frequencies and package forms, so as to adapt to varied types of applications.
  When the applied S-pole or N-pole magnetic induction intensity is higher than the working point Bor, the chip outputs low level and keeps it,until the S-pole or N-pole magnetic induction intensity is lower than the release point Ba, when the chip outputs high level.

• The chip is installed with a temperature compensation circuit and a clock logic circuit intemally, to ensure stable working point and switching frequency of the chip.The chip can provide omnipolar magnetism response with extremely low current consumption.

• SL1603 can work during the power supply ranges of 1.6V to 5.5V.with standard SOT-23 package.
