3 说明
DRV5053 器件是一款斩波稳定霍尔 IC,能够在整个温度范围内提供具有出色灵敏度稳定性和集成保护特性的磁场感测解决方案。
0V 至 2V 模拟输出可对施加的磁感应强度做出线性响应,并且能够辨别磁场方向的极性。 反向极性保护高达 -22V 的宽工作电压范围(2.5V 至 38V)使得此器件适用于广泛的工业和消费类应用。
针对反向电源情况、负载突降和输出短路或过流提供内部保护功能。
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.
