描述
DRV5023 器件是一款斬波穩定霍爾效應傳感器,能夠在整個溫度范圍內提供具有出色靈敏度穩定性和集成保護特性的磁場感測 解決方案。
當應用的磁通量密度超過 BOP 閾值時,DRV5023 開漏輸出變為低電平。輸出將保持低電平,直到磁通量密度降至 BRP 以下之后變為高阻抗。輸出灌電流能力為 30mA。反向極性保護高達 -22V 的寬工作電壓范圍(2.5 至 38V)使得此器件廣泛適用于各種工業 信號。
該器件提供針對反向電源情況、負載突降以及輸出短路或過流故障的內部保護功能。

7.1 Overview
The DRV5023 device is a chopper-stabilized Hall sensor with a digital output for magnetic sensing applications. The DRV5023 device can be powered with a supply voltage between 2.5 and 38 V, and will survive –22 V reverse-battery conditions. The DRV5023 device does not operate when –22 to 2.4 V is applied to the VCC pin (with respect to GND pin). In addition, the device can withstand supply voltages up to 40 V for transient durations.
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.
The output state is dependent on the magnetic field perpendicular to the package. A strong south pole near the marked side of the package causes the output to pull low (operate point, BOP), and a weak south pole causes the output to release (release point, BRP). Hysteresis is included in between the operate point and the release point therefore magnetic-field noise does not accidentally trip the output.
An external pullup resistor is required on the OUT pin. The OUT pin can be pulled up to VCC, or to a different voltage supply. This allows for easier interfacing with controller circuits.
