| Package | SIP-4 | Model Number | A1366LKTTF-1-T |
The Allegro A1366 is a factory-programmable linear Hall-effect current sensor IC designed for high accuracy and resolution in current sensing applications. It features proprietary linearly interpolated temperature compensation technology, ensuring virtually flat sensitivity and offset across its operating temperature range. This IC is ideal for demanding applications such as HEV inverters, DC-to-DC converters, and electric power steering (EPS). Its ratiometric analog output is proportional to the applied magnetic field, offering industry-leading sensing resolution at a 120 kHz bandwidth. The device also includes built-in broken ground wire detection for enhanced reliability in automotive environments.
