Diodes Incorporated AH1388 Dual-Output Unipolar Hall Effect Switch

Diodes Incorporated AH1388 Dual-Output Unipolar Hall Effect Switch is optimized for portable and battery-powered consumer equipment. The AH1388 can operate from a 1.6V to 3.6V power supply range, and uses a sleep function to give an average supply current of only 12μA at 1.85V. These low-power attributes make the AH1388 ideal for battery-powered equipment and low voltage microcontrollers. To minimize PCB space, the AH1388 is packaged in small low profile X2-DFN1410-4.
