Worcester, MA – Allegro MicroSystems, LLC announces a new factory-programmable linear Hall-effect current sensor IC. Allegro’s A1366 has been designed to achieve high accuracy and resolution. The goal is achieved through new proprietary linearly interpolated temperature compensation technology that is programmed at the Allegro factory, which provides sensitivity and offset that are virtually flat across the full operating temperature range. The flat performance over temperature makes this IC ideally suited for current sensing applications. Temperature compensation is done in the digital domain with integrated EEPROM technology without sacrificing the analog signal path bandwidth. The A1366 high frequency operation was designed for HEV inverter, DC-to-DC converter, and electric power steering (EPS) applications, but can be used for any current sensing system requiring high bandwidth operation.

This ratiometric Hall-effect sensor IC provides a voltage output that is proportional to the applied magnetic field. Sensitivity and quiescent (zero field) output voltage are factory programmed with high resolution providing an accuracy of less than ±1%, typical, over the full operating temperature range. The sensor IC incorporates a highly sensitive Hall element with a BiCMOS interface integrated circuit that employs a low noise, small-signal high-gain amplifier, as well as a low-impedance output stage, and a propri¬etary, high bandwidth dynamic offset cancellation technique. These advances in Hall-effect technology provide an industry leading sensing resolution at the full 120 kHz bandwidth. The device’s broken ground wire detection is also built into the device for high reliability in automotive applications.

Device parameters are specified across an extended ambient temperature range: –40°C to 150°C. The A1366 sensor IC is provided in an extremely thin case (1 mm thick), 4-pin SIP (single in-line package, suffix KT) that is lead (Pb) free, with 100% matte tin lead frame plating.
