Hall-Effect Sensors Integrate MCUs

Chiseled for automotive and mechatronic designs, the HAL 28xy series Hall-effect sensors are reportedly the first to include a microcontroller (MCU), temperature sensor, on-chip compensation, and a digital interface. The Hall-effect and temperature sensors each have their own a/d converter, allowing the MCU to perform spinning-current offset compensation and first-order temperature compensation for Hall offset error and second-order temperature compensation. The sensors also integrate EEPROM for storing applications and the digital interface drives the serial bus directly. Series members include devices with a LIN bus, SENT, and PWM. For design support, an application kit is available containing a programmer board, LabVIEW programming software, and all necessary source code. All HAL 28xy sensors are available in TO-92UT packages with an operating temperature range from -40°C to +140°C. MICRONAS USA INC., Santa Clara, CA. (408) 625-1200.
