AH180 – Micropower Omnipolar Hall-Effect Sensor Switch
AH180 integrates two Hall Effect plates and an open-drain output driver, mainly designed for battery-operation, hand-held equipment (such as Cellular and Cordless Phone, PDA). The total power consumption in normal operation is typically 24μW with a 3V power source.
Either north or south pole of sufficient strength will turn the output ON (Low). The output will be turned OFF (High) under no magnetic field. While the magnetic flux density (B) is larger than operating point (Bop), the output will be turned ON (Low), the output is held until B is lower than release point (Brp), and then turned OFF (High).
The AH180 is rated for operating temperature range from -40°C to 85°C. To accommodate different printed circuit board assembly needs the AH180 is offered in both through-hole (SIP-3L) and surface mount (SC59-3L, DFN2020-6, DFN2020-3) device type packages.
The AH180-SNG-7 is a DFN2020-6 Micropower Omnipolar Hall-Effect Sensor Switch that comes in a 3000 piece reel.
