AH1883 MICROPOWER, ULTRA-SENSITIVE HALL EFFECT SWITCH Description The AH1883 micropower Omnipolar Hall Effect switch IC is designed for portable and battery powered equipment such as cellular phones, cordless phones, camcorders, PDA’s, and portable PC’s. Based on two high sensitivity Hall Effect plates and chopper stabilized architecture, the AH1883 provides reliable solution over the whole operating range. To support portable and battery powered equipment the design has been optimized to operate from 1.65V to 3.3V and consumes 13uW typical with a supply of 1.8V. To minimize PCB space the AH1883 incudes a push-pull output structure, therefore does not require an external pull up resistor, and is packaged in small low profile SOT553 and U-DFN2020-3 packages.
