What the GH1248 does
The GH1248 is a micropower, high-sensitivity omnipolar Hall-effect switch featuring a digital latched output. It operates across 1.8 to 5.5 V power supplies and supports both north and south magnetic poles. The device offers 1.8 V minimum supply voltage, 1.3 mA maximum awake current, and 1.5 μA sleep current. It includes a built-in pull-up resistor and stabilized chopper amplifier for superior temperature stability. Engineers typically use the GH1248 in cover switches for notebook PCs, handheld wireless devices, and low-duty-cycle magnet applications. Available in SIP-3L, SOT-23-3L, and DFN1616-3 packages, it optimizes battery operation for hand-held equipment.
