AH1803 Datasheet | Diodes Incorporated

Description The AH1803 has two Hall effect plates and a CMOS output driver. The device is primarily designed for battery-operated, handheld equipment (such as cellular and cordless phones, PDAs). The total operation power is down to 24µW in the 3V supply. Either the north or south pole turns the output on with sufficient strength. The output turns off under no magnetic field. While the magnetic flux density (B) is larger than operate point (Bop), the output turns on (low). The output is held until B is lower than release point (Brp) then turns off (high). Features - Micropower Operation - Operation with North or South Pole - 2.4 to 5.5V Battery Operation - Chopper Stabilized - Superior Temperature Stability - Extremely Low Switch-Point Drift - Insensitive to Physical Stress - Good RF Noise Immunity - -40°C to +85°C Operating Temperature - Low-Profile 3-Pin SC59 (monly Known as SOT23 in Asia) and DFN2020-6 Package - ESD (HBM) > 4KV for DFN2020-6 - SC59 (monly known as SOT23 in Asia) and DFN2020-6: Available in “Green” Molding pound (No Br, Sb) - Lead-Free Finish; Ro HS pliant (Notes 1 & 2) - Halogen and Antimony Free. “Green” Device (Note 3) Pin Assignments (Note 4) SC59 (monly known as SOT23 in Asia) ( Top View ) GND 3. 2.

See https://.diodes./quality/lead-free/ for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free. 3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm antimony pounds. 4. NC is “No Connection”, which is remended to be tied to ground. Document number: DS31193 Rev. 10 - 3 1 of 8 .diodes. April...
