GX1791-GX 1791Micropower Dual HallOutput SwitchThe GX1791 micro power Omni-polar Hall Effect switch IC have two output options and designed for portable and battery powered equipment such as cellular phones, PDA' s and portable PC' s. Based on two sensitive Hall Effect plates and chopper stabilized architecture the GX1791 provides a reliable solution over the whole operating range. The outputs are switched with either a north or south pole of sufficient strength. When the magnetic flux density (B) is larger than operate point (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. The GX1791 has two outputs, output one pulls low when switched on and output two is inverted. The GX……
