Freiburg, GermanyOptimized for automotive and mechatronic applications, Micronas announced the HAL 28xy series of Hall-effect sensors, which integrate a microcontroller (MCU), a temperature sensor, advanced on-chip compensation, and a digital interface.
With the programmable on-chip MCU, HAL 28xy devices are flexible and capable of providing diagnostics for additional reliability and ease of service. The digital interface reduces component and wiring costs, making HAL 28xy family members cost-effective for applications such as seat-track position and fuel-level sensing.
The Hall-effect sensor and on-chip temperature sensor each has its own A/D converter. This lets the MCU perform spinning-current offset compensation, plus first-order temperature compensation for Hall offset error and second-order temperature compensation for overall Hall-effect sensitivity. The on-chip EEPROM makes it possible to store custom individualized application parameters in each device.
The implemented bus interface can drive the serial bus directly because the bus-driver is fully integrated. Both the power supply and the serial bus connections are protected by over-voltage devices.
All HAL 28xy family members are offered in a TO-92UT package rated for use
from -40° to +140°C.
Pricing and availability vary with model.
