IFXTLE4946-2K
Overview
The TLE4946-2K is a high-precision Hall effect latch designed for commutation in brushless DC (BLDC) motors and position sensing in automotive and industrial environments. It operates from a wide supply voltage range of 2.7V to 18V and features an open-collector output with active error compensation to minimize mechanical stress effects. The sensor provides superior temperature stability and integrated reverse battery protection, making it suitable for harsh operating conditions.
Why Choose This Part
This sensor offers high sensitivity with a typical 3.5mT trip point and integrated temperature compensation for consistent switching performance up to 150 degrees Celsius. Its active error compensation circuit significantly reduces jitter and offset drift caused by mechanical stress on the SC59 package.
Applications
Key Specifications
Getting Started
To implement this sensor, connect a pull-up resistor (typically 1k to 10k ohms) between the open-collector output and the logic supply. Ensure a bypass capacitor of at least 100nF is placed close to the VDD and GND pins to filter supply noise in motor-heavy environments.
