TPS281C100 Evaluation Module
Description
The TPS281C100EVM is a hardware evaluation
module (EVM) used to enable hardware engineers
to evaluate the full performance and functionality of
the TPS281C100 industrial high side switch. The
TPS281C100EVM contains everything needed to test
and assess the TPS281C100 before designing into
part of a greater application's power system. The
evaluation module is designed to either be used as a
standalone board with an attached voltage supply and
output load or in conjunction with an underlying Texas
Instruments microcontroller by using the standardized
BoosterPack
™
plug-in module headers. A wide range
of application features such as digital output module,
safe torque off (STO), and holding brake are enabled
and visible through use of this evaluation module.
This EVM is populated with the QFN version of
TPS281C100.

TPS281C100 industrial high side switch. This evaluation board provides a seamless way to connect a set of power supplies to the inputs of the TPS281C100, connect loads to the output channels, and switch on and off the device using the control pins of the chip itself. An on-board 3.3-V LDO is included on the EVM to simplify controlling signals to the TPS281C100 and easily assert and deassert logic signals by the use of a set of external hardware jumpers. -
Page 3: Connection Descriptions
Jumpers J6 through J8 are used to manually configure the control signals going into the TPS281C100. When using a microcontroller to control these signals, these jumpers must be unpopulated to allow for the microcontroller to drive them high or low. -
