TLI4970 Current Sense

In stock


TLI4970 is a high-precision current sensor based on Infineon´s proven Hall technology. The coreless concept significantly reduces footprint compared with existing solutions. TLI4970 is an easy-to-use, fully digital solution that does not require external calibration or additional parts such as A/D converters, 0 pAmps or reference voltage. It thus significantly reduces overall implementation efforts as well as PCB space and cost.
