The TLI4971-A120T5 is a core-less openloop current sensor based on Infineon´s proven Hall technology. It offers a high level of flexibility as customers can individually program product parameters. It addresses industrial applications such as electric drives up to 30 kW. The offers an accurate and stable current measurement – provided as an analog output voltage. Based on Infineon’s market-proven temperature and stress compensation the sensitivity error is as low as 2 percent at room temperature. Furthermore, differential measurement with two Hall cells ensures high accuracy even in a noisy environment with cross-talk from adjacent current lines or magnetic stray fields.

Infineon has extended its portfolio of coreless current sensors with the new TLI4971. It relies on a Hall-based magnetic sensing principle with an integrated current rail offering smallest footprint resulting in an overall system size reduction.
In addition a differential measurement principle makes the current sensor stray-field robust, furthermore an ultra- fast analog output path offers a bandwidth of up to 120kHz. Paired with 2 programmable overcurrent channels the current sensor is a perfect fit for industrial applications such as drives and inverters.
