  DRV5053 器件是一款斬波穩(wěn)定霍爾 IC,能夠在整個(gè)溫度范圍內(nèi)提供具有出色靈敏度穩(wěn)定性和集成保護(hù)特性的磁場(chǎng)感測(cè)解決方案。
  0V 2V 模擬輸出可對(duì)施加的磁感應(yīng)強(qiáng)度做出線性響應(yīng),并且能夠辨別磁場(chǎng)方向的極性。 反向極性保護(hù)高達(dá) -22V 的寬工作電壓范圍(2.5V 38V)使得此器件適用于廣泛的工業(yè)和消費(fèi)類應(yīng)用。
  針對(duì)反向電源情況、負(fù)載突降和輸出短路或過(guò)流提供內(nèi)部保護(hù)功能。
  The DRV5053 device is a chopper-stabilized hall sensor with an analog output for magnetic sensing applications. The DRV5053 device can be powered with a supply voltage between 2.5 and 38 V, and will survive –22 V reverse battery conditions continuously. Note that the DRV5053 device will not be operating when approximately –22 to 2.4 V is applied to VCC (with respect to GND). In addition, the device can withstand supply voltages up to 40 V for transient durations.
  The output voltage is dependent on the magnetic field perpendicular to the package. The absence of a magnetic field will result in OUT = 1 V. A magnetic field will cause the output voltage to change linearly with the magnetic field.
  The field polarity is defined as follows: a south pole near the marked side of the package is a positive magnetic field. A north pole near the marked side of the package is a negative magnetic field.
  For devices with a negative sensitivity (that is, DRV5053RA: –40 mV/mT), a south pole will cause the output voltage to drop below 1 V, and a north pole will cause the output to rise above 1 V.
  For devices with a positive sensitivity (that is, DRV5053EA: +40 mV/mT), a south pole will cause the output voltage to rise above 1 V, and a north pole will cause the output to drop below 1 V.
