Analog interface and dual fast over-current detection output, UL certified – for industrial applications
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.
