GENERAL DESCRIPTION
E.g. as an On/Off switch in Cellular Flip-Phones, with battery operating voltages of 2.4V-5.5V. Either north or south pole of sufficient strength will turn the output on. While the magnetic flux density (B) is larger than operate point (Bop), the output will be turned on (low), the output is held until B is lower than release point (Brp), then turned off.● Typical Application Circuit VDD 1uF LN4912 VOUT GND
