TPS3842 Evaluation Module
Description
The TPS3842EVM is an evaluation module (EVM)
for the TPS3842-Q1 and TPS3842 family of voltage
supervisors. The purpose of the this EVM is to provide
a sample design and test point for all input and output
pins of the TPS3842 and TPS3842-Q1 device to
capture measurements and gain familiarity with the
device.
