The TMCS1123 is an isolated, Hall-effect based, current-sense amplifier that provides ease-of-use and high performance. The TMCS1123xEVM is a family of EVMs intended to provide basic, functional evaluation of all TMCS1123 sensitivity variants.

The TMCS1123xEVMs are not laid out for electromagnetic compatibility (EMC) testing. The TMCS1123xEVM family consists of three separate orderable PCBs that can be snapped apart into five individual segments, with each segment populated with a separate sensitivity. Each PCB allows testability of all sensitivity variants across one of the three orderable reference points of 0.5 × VS (TMCS1123AEVM), 0.33 × VS (TMCS1123BEVM), or 0.1 × VS (TMCS1123CEVM).

Across all EVM variants, the parts that can be examined with the EVM are:

  • TMCS1123A1
  • TMCS1123A2
  • TMCS1123A3
  • TMCS1123A4
  • TMCS1123A5
  • TMCS1123B1
  • TMCS1123B2
  • TMCS1123B3
  • TMCS1123B4
  • TMCS1123B5
  • TMCS1123C1
  • TMCS1123C2
  • TMCS1123C3
  • TMCS1123C4
