SBOSAG1 July 2024 TMCS1133-Q1
PRODUCTION DATA
For a 3-phase current sensing application, make sure to provide linear sensing across the expected current range, and make sure that the device remains within working thermal constraints. A single TMCS1133-Q1 can be used to measure current in each phase if necessary. For this example, consider a nominal supply of 5V but a minimum of 4.9V to include for some supply variation. Maximum output swings are defined according to TMCS1133-Q1 specifications, and a full-scale current measurement of ±20A is required.
