Description

The AH1883 micropower Omnipolar Hall Effect switch IC is designed for portable and battery powered equipment such as cellular phones, cordless phones, camcorders, PDA’s, and portable PC’s. Based on two high sensitivity Hall Effect plates and chopper stabilized architecture, the AH1883 provides reliable solution over the whole operating range. To support portable and battery powered equipment the design has been optimized to operate from 1.65V to 3.3V and consumes 13uW typical with a supply of 1.8V. To minimize PCB space the AH1883 incudes a push-pull output structure, therefore does not require an external pull up resistor, and is packaged in small low profile SOT553 and DFN2020-3 packages Either North or South pole of sufficient strength will turn the output on. When the magnetic flux density (B) is larger than operate (Bop) the output is switched on. The output is turned off when B becomes lower than the release point (Brp). The output will remain off when there is no magnetic field.

Application(s)

• Cellular phones • PDA • Portable PCs - Netbook, Notebook, Tablets and PDAs • Camcorders • Handhel game consoles • Cordless phone • Contact-less switch in portable and battery powered applications
