AH1381/2/3 Digital Unipolar Hall-Effect Switch ICs

Diodes Incorporated AH1381, AH1382, and AH1383 Digital Unipolar Hall-Effect Switch ICs are high-sensitivity, ultra-low-power components with a hibernating clocking system. This system allows an average supply current of 1.6μA at 3V, making the AH138x ICs perfect for battery-powered consumer products, gas/water meters, smoke detectors, and Internet of Things (IoT) devices. A wide 1.6V to 5.5V supply voltage extends battery operating times and supports low-voltage system microcontrollers. The advanced chopper stabilized design provides superior stability on the switch operating point over temperature and supply voltage, while the high 8kV ESD level ensures system robustness. AH138x ICs are available in a SOT23 (Type S), a small low-profile X2-DFN1410-4, or X2-DFN1010-4 (Type B) package type.
