Hall effect integrated circuit current sensor A1365 series

PCBDC

The A1365 linear output Hall-effect sensor IC is specifically designed to provide a highly accurate output with improved resolution at high bandwidth for use in current-sensing applications. This device employs a segmented, linearly interpolated temperature compensation technology, which provides greater accuracy in sensitivity and offset voltage trimming and hence virtually zero temperature drift. This improvement greatly reduces the total error of the device across the operating temperature range. The highly programmable Over Field Fault signal (FAULT pin) can be used to detect a high magnetic field condition. Broken ground wire detection, undervoltage lockout for VCC below specification, and user-selectable output voltage clamps are also included, which are important for high reliability in automotive applications. The sensor accuracy and diagnostic capability make it ideally suited for automotive sockets such as HEV inverter and DC-to-DC converter applications. The A1365 Hall-effect sensor IC is extremely sensitive, fast, and temperature-stable. The accuracy and flexibility of this device is enhanced by user programmability, performed via the VCC supply and the output pins, which allows the device to be optimized in the application. This ratiometric Hall-effect sensor IC provides a voltage output that is proportional to the applied magnetic field. The quiescent output voltage is user-adjustable around 50% (bidirectional) of the supply voltage, VCC. The device sensitivity is adjustable within the range of 0.6 to 14 mV/G.
