A1363LLUTR-2-T

• Product Introduction

The A1363LLUTR-2-T is a low-noise, high-precision, programmable linear Hall-effect sensor IC with advanced temperature compensation and high-bandwidth (120 kHz) analog output

A1363LLUTR-2-T Low-noise, high-accuracy, programmable linear Hall-effect sensor with advanced temperature compensation and high-bandwidth (120 kHz) analog output The Allegro A1363 programmable linear Hall-effect current sensor IC is designed for high accuracy and resolution without sacrificing bandwidth. This is achieved through a new patented linear interpolated temperature compensation technology that is programmed at the Allegro factory and provides virtually uniform sensitivity and offset over the entire operating temperature range. Temperature compensation is done using integrated EEPROM technology within the digital domain without sacrificing the 120 kHz bandwidth of the analog signal path, making the device ideal for HEV inverter and DC-to-DC converter applications.

This proportional Hall-effect sensor IC provides a voltage output proportional to the applied magnetic field. Customers can configure sensitivity and static (zero field) output voltages through VCC and output pin programming to optimize performance in end applications. The quiescent output voltage can be adjusted by the user to approximately 50% of the supply voltage (VCC), and the output sensitivity can be adjusted from 0.6 to 14 mV/G.

The sensor IC contains a highly sensitive Hall element with a BiCMOS interface integrated circuit that uses a low-noise, low-signal, high-gain amplifier, clamping, low-impedance output stage, and high-bandwidth dynamic offset cancellation proprietary technology. These Hall-effect technological advancements guarantee industry-leading sensing resolution while maintaining full bandwidth of 120 kHz. The device also has built-in ground wire break detection and user-selectable output voltage clamping to meet the high reliability requirements of automotive applications.

The device parameters are suitable for a wider ambient temperature range: –40°C to 150°C. The A1363 sensor IC is available in an ultra-thin (1 mm thick) 4-pin SIP (single in-line package, suffix: KT) in a lead-free package with 100% matte tin plating on the pin frame.
