A1160 with external startup diagnostic function is a unipolar hall effect switch.Working in normal mode, A1160 can be used as a standard unipolar hall effect switch.If there is enough magnetic field (> BThe OP(Max)), the output transistor will start (output signal switching to low).If cancel the magnetic field (< BThe RP(minimum)), A1160 output transistor will be closed (output signal switching to high).
A1160 with conductive coil, the coil near the hall element.When the diagnosis function starts, these coil electricity.Electric coil can be hall element internal magnetic field induction.In the diagnosis of mode, A1160 can provide square wave output, this can be confirmed, IC right induction magnetic field is generated inside it.Diagnosis model can be run inside the IC of the electromagnetic signal path, fully confirmed its functionality.Therefore, for safety critical applications need redundant sensors (line control system, etc.), if use A1160, you should use redundant sensor, can improve the relevant application robustness.
A1160 hall effect sensor IC at various temperatures are extremely stable and compressive properties, especially suitable for temperature up to 150 ° C.Advanced dynamic offset cancellation technique to ensure the good performance under high temperature, can reduce usually by supermodel pressure device, temperature dependency and the thermal stress caused by the residual offset voltage.The devices on a single silicon chip is equipped with the following components: voltage regulator, hall voltage generator, small signal amplifier, a stable chopper device, Schmitt trigger and maximum infusion 25 mA current open collector output.On-board regulator allows the use of 3.8 to 24 V power supply voltage.
A1160 SOT23W encapsulation using 5 needle.Fog the encapsulated as lead-free packaging, with 100% of tin plating pin frame.
