TPS7H2140-SEP Evaluation Module (EVM)
Description
The TPS7H2140EVM provides a platform to
demonstrate the operation and features of the
TPS7H2140-SEP eFuse. The EVM provides test
points, jumpers, connection terminals, and labeled
easy-to-access components allowing for customized
configurations of device features. The board also
includes a voltage regulator to enable device
functionality without the need for secondary power
sources for IO configuration.
