Description
The AH1804 is a micropower Omnipolar Hall effect switch IC
with a single output driver with internal pull up and pull down
capability. Designed for portable and battery powered
equipment such as cellular phones and portable PCs the
average supply current is only 12礎(chǔ) at 3.3V. To support
battery powered equipment the AH1804 can operate over the
supply range of 2.5V to 3.6V and uses a hibernating clocking
system to minimize the power consumption.
The output is activated with either a north or south pole of
sufficient strength. When the magnetic flux density (B) is
larger than operate point (Bop), the output will be turned on
(pulled low) and held until B is lower than release point (Brp).
The AH1804 is available in SC59 and small low profile
DFN1216-4 packages.
