Summary

TI’s TPS272C45C high-side switch is designed to be used in industrial applications. In industrial SELV systems, the bus voltage can be up to 60V. While TPS272C45C is designed for nominal 24 V industrial systems, with some modifications to the surrounding circuit, the device can survive 60 V without being damaged. An example of the circuit implementation, as well as the test results, are presented in this report. With the increasing demand for system safety compliance and requirements for 60 V tolerance, the variant of TPS272C45 that doesn’t have an internal VDS clamp is still suitable in typical industrial applications and can be protected from different faults cases including surge and 60 V VS.
