Diodes Incorporated | AH1802-WG-7

Diodes Incorporated designs, manufactures and markets high-quality discrete and analog semiconductor application-specific standard products with focus on high-growth applications in the consumer electronics, computing, communications, industrial and automotive markets.

Diodes' analog products include Hall Effect sensor integrated circuits for position and speed detection and, through acquisition of Zetex Inc., a comprehensive range of magnetoresistive sensors (with or without an internal magnet) for linear and angular position measurement.

AH1802 integrates two Hall Effect plates and an open-drain output driver and is 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, the output is held until B is lower than release point (Brp), and then turned OFF.

The AH1802 is rated for operating temperature range from -40°C to 85°C and is offered in surface mount device type packages SC59-3L, DFN2020-6, and DFN2020-3.

The AH1802-WG-7 is a SC59-3L Micropower Ultra-sensitive Omnipolar Hall-Effect Switch that comes in a 3000 piece reel.
