ROHM Hall Effect Sensor Surface, CMOS Output, Block Body 4.5V

The ROHM Omni polar detection Hall IC incorporating a polarity determination circuit enables separate operation (output) of both the South and North poles. Using a magnet and the Hall IC, detection of open and close of the cover are possible in smart phones and tablets, and detection of putting wireless earphones in a case, and detection of front/back side or rotational direction are possible in digital cameras and other applications involving display panels.

• Omni polar detection (OUT1 = S-pole detection; OUT2 = N-pole detection)
• Micro power operation (small current using intermittent operation method)
• Ultra-compact package
