■Recommended Operating Range
Parameter Symbol Range Unit
Supply voltage VCC 2.5 to 3.5 V
■Absolute Maximum Ratings
Parameter Symbol Rating Unit
Supply voltage VCC 5V
VOUT 5V
Output current IO15 mA
Power dissipation PD60 mW
Operating ambient temperature Topr −20 to +75 °C
Storage temperature Tstg −55 to +125 °C
Note) 1. Except for the operating ambient temperature and storage temperature, all ratings are for Ta = 25°C.
2. The reverse insertion of this IC will cause its breakdown.
3. It will operate normally in several tens of ms after power on.
4. This IC is not suitable for car electrical equipment.
Note) 1. Symbol BH-L stands for the operating magnetic flux density where its output level varies from high to low.
2. Symbol BL-H stands for the operating magnetic flux density where its output level varies from low to high.
3. ICCON is a consumption current when the magnetism detection system is on, and ICCOFF is that when the magnetism detection
system is off. One magnetism detection cycle is On = 200 µs and Off = 51 ms. ICCAVE is an average consumption current.
