6 / 12 page Low Current Ultrasensitive Two-Wire Chopper-Stabilized Unipolar Hall Effect Switches A1147 and A1148 6 Allegro MicroSystems, Inc. 115 Northeast Cutoff, Box 15036 Worcester, Massachusetts 01615-0036 (508) 853-5000 www.allegromicro.com Functional Description BHYS ICC(H) ICC(L) B+ B– I+ 0 (A) A1147 BHYS ICC(H) ICC(L) B+ I+ B– 0 (B) A1148 Operation The output, ICC, of the A1147 device switches low after the mag- netic field at the Hall sensor exceeds the operate point threshold, BOP. When the magnetic field is reduced to below the release point threshold, BRP, the device output goes high. The differ- ences between the magnetic operate and release point is called the hysteresis of the device, BHYS. This built-in hysteresis allows clean switching of the output even in the presence of external mechanical vibration and electrical noise. The A1148 device switches with opposite polarity for similar BOP and BRP values, in comparison to the A1147 (see figure 1). Figure 1. Alternative switching behaviors are available in the A114x device family. On the horizontal axis, the B+ direction indicates increasing south polarity magnetic field strength, and the B– direction indicates decreasing south polarity field strength (including the case of increasing north polarity). |
