AN488xx principle of operation

High sensitivity, ultra low current Hall effect position and proximity sensingHall sensor IC - AN488xx series

OverviewPanasonic hall effect position and proximity sensor ICs “AN488xx series” achieve industry leading sensitivity / power consumption performance. The average supply current can be kept as low as 3μA by using intermittent sensing and CMOS output latch. The high sensitivity of the AN488xx series sensors allow the use of reasonable ferrite magnets. Omnipolar switch (AN48836) and bipolar latch (AN48841/AN48846) variants support a variety of applications including open / close detection, proximity detection, position detection of rotating objects.

Features and benefits• Very high sensitivity, supports reasonable magnet• Industry leading low power consumption down to 3 μA• CMOS latch output.• Space saving SMINI-5DE package 2.0 × 2.1 × 0,7mm³• RoHS compliant.

ApplicationsOpen/close detection, Proximity detection,Position detection of rotating parts, Battery powered electronic devices, Power tools, white goods.
