Magnetic Current Sensor

Miniature Magnetic Digital Current Sensor ±50A (AC/DC), up to ±1%, Digital SPI Interface

The TLI4970 is a high-precision current sensor based on Infineon´s proven Hall technology. The coreless concept significantly reduces footprint compared with existing solutions.

An easy-to-use, fully digital solution, the TLI4970 does not require external calibration or additional parts such as A/D converters, OP amps or reference voltage. It significantly reduces overall implementation effort as well as PCB space and cost.


Product Features

 

 TLI4970 is more accurate than existing open- or closed-loop systems with magnetic cores. It also provides additional functions such as overcurrent detection and programmable filters yet has a significantly smaller footprint and lower power consumption.

 TLI4970 is extremely robust against external magnetic fields thanks to implemented strayfield suppression and is also suitable for fast overcurrent detection at a pre-configurable level. This allows the control unit to switch off independently of the main measurement path and protect power consumers from damage.

   TLI4970 Current Rail
  • AC & DC measurement range up to ±50A
  • Highly accurate over temperature range and lifetime (max. 1.0% (0 h), 1.6% (over lifetime) of indicated value)
  • Low offset error (max. 75mA over temperature and lifetime)
  • High magnetic stray field suppression
  • Fast over current detection with configurable threshold
  • Galvanic isolation up to 2.5kV max. rated isolation voltage (UL1577)
  • 16-bit digital SPI output (13-bit current value)
  • Small 7.0 x 7.0 mm SMD package
