Product Specification
| Description | SIP-4 Linear, Compass (ICs) RoHS | Mfr. Part # | A1366LKTTF-10-T |
| Package | SIP-4 | Model Number | A1366LKTTF-10-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 for virtually flat sensitivity and offset across its operating temperature range. This device is ideal for demanding applications such as HEV inverters, DC-to-DC converters, and electric power steering (EPS). With a ratiometric voltage output proportional to the applied magnetic field, it offers industry-leading sensing resolution at a 120 kHz bandwidth. Integrated features like broken ground wire detection and undervoltage lockout enhance reliability in automotive environments.
