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, under voltage 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 an the output pins, which allows the device to be optimized in the application.
The A1365 sensor IC is provided in an extremely thin case (1 mm thick), 4-pin SIP (single inline package, suffix KT) that is lead (Pb) free, with 100% matte-tin leadframe plating. The thin package allows for better magnetic coupling because the smaller the air gap in the core is, the higher the coupling from current to magnetic field will be.
