The BU52777GWZ is an omnipolar Hall effect IC with dual CMOS outputs for detecting both north and south magnetic poles, used in applications such as smart phones, tablets, and wireless earphones for cover detection. It operates from 2.5 V to 4.5 V with a typical supply current of 1.7 µA and a 50 ms period. The device has a typical operate point of ±15 mT and hysteresis of 2 mT, with an operating temperature range of -40 °C to +85 °C. It is packaged in an ultra-compact UCSP35L1 measuring 0.80 mm x 0.80 mm x 0.40 mm. The -E2 suffix indicates tape and reel packaging, which is consistent with the series description.
