板机接口霍耳效应/磁性传感器 POSITION&CURRENT; SENSORS
Description:
The TLE5009A16D is an angle sensor with analog outputs. It detects the orientation of a magnetic field by measuring sine and cosine components with Giant Magneto Resistive
GMR elements. It provides analog sine and cosine output voltages that describe the magnet angle in a range of 0° to 360°.
The differential GMR bridge signals are independent of the magnetic field strength, and the output voltages are designed to use the dynamic range of an A/D-converter using the same supply as the sensor as voltage reference.
The TLE5009A16D is a dual die sensor for safety applications that require redundancy. The two dies are supplied independently by separate supply and ground pins.
Summary of Features:
- .
- Dual die sensor with separate supplies for each die
- .
- Low current consumption and very fast power up
- .
- 360° contactless angle measurement
- .
- Immune to airgap variations due to MR based sensing principle
- .
- Operating temperature: -40°C to 125°C ambient temperature
Target Applications:
The TLE5009A16D angle sensor is designed for angular position sensing automotive applications. Its high accuracy and 360° measurement range combined with short propagation delay makes it suitable for systems with high speeds and high accuracy demands such as brush-less DC BLDC motors for actuators and electric power steering systems EPS. At the same time its fast power-up time and low overall power consumption enables the device to be employed for low-power turn counting. Extremely low power consumption can be achieved with power cycling, where the advantage of fast power on time reduces the average power consumption.
The TLE5009A16D is also used in various non-automotive applications.
