AH1388中文资料ULTRA SENSITIVE DUAL OUTPUT UNIPOLAR HALL EFFECT SWITCH数据手册Diodes规格书

描述 Description

The AH1388 is a miniature micropower magnetic Unipolar Hall effect switch IC with dual outputs specifically designed for portable and battery-powered consumer equipment to home appliances and industrial applications. To support battery-powered equipment and low voltage microcontrollers, the AH1388 can operate over the supply range of 1.6V to 3.6V and uses a sleep function to give an average supply current of only 12μA at 1.85V. To minimize PCB space, the AH1388 is packaged in small low profile X2-DFN1410-4.

A North pole of sufficient strength will turn Output1 on and a South pole of sufficient strength will turn on Output2. The Output1 is turned on (pulled low) when the magnetic flux density (B), perpendicular to the part marking surface, falls below North field operate point BOPN (-17G typical). The Output1 is held low until B rises above the North field release point BRPN (-11G typical). Similarly, the Output2 will operate (pulled low) when B to the part marking surface rises above South field operate point BOPS (17G typical) and is held low until B falls below the South field release point BRPS (11G typical).
