Digital Micropower Omnipolar Hall IC 9 Magnetic Behavior When the magnet (S or N pole) is close to the sensor (|B|≥|BOP|), the sensor outputs a low level; when the magnet is far away from sensor (|B|≤|BRP|), the sensor outputs a high level. Steady Hysteresis (BHX=|BOPX- BRPX|) ensures its stable switch status. The magnetoelectric conversion characteristics of AH3661 are shown in the figure: Vout switch to high Vout switch to high Omnipolar Switch Nanjing AH Electronic Science & Technology Co., Ltd.

Digital Micropower Omnipolar Hall IC Low Average Power Internal timing circuit activates the IC for 45 µs and deactivates it for the remainder of the period (45 ms). A short "awake" time allows for stabilization prior to the sampling and data latching on the falling edge of the timing pulse. The output during the "sleep" time is latched in the last sampled state. The supply current is not affected by the output state. IAWK Period Sleep Period Nanjing AH Electronic Science & Technology Co., Ltd.
