Omnipolar Detection Hall IC
STH8103
■DESCRIPTION
Micro Power, Ultra-Sensitive, Hall Effect Switch
■FEATURE
STH8103 is a three-terminal Hall Effect sensor device with a output driver, mainly designed for battery–operation, hand-held equipment (such as Cellular and Cordless Phone, PDA). For STH8103, either north or South Pole of sufficient strength will turn the output on. The output will be turned off under no magnetic field. While the magnetic flux density (B) is larger than operate point (Bop), the output will be turned on (low), the output is latched
until B is lower than release point (Brp), then turned off.
2.4V to 5.
