Introduction
This EVM helps design engineers evaluate the operation and performance of the TPS3831yxx family of
supervisors for possible use in their own circuit application. This particular EVM configuration contains the
TPS3831G33 supervisor with an internal push-pull RESET output, in a 1 × 1 mm DQN µSON package.
The TPS3831yxx is an ultra- low quiescent current, supervisory circuit with a fixed threshold voltage. The
threshold voltage is indicated by the last two digits of the part number, with 33 indicating the fixed 3.3-V
version and other values indicating various fixed thresholds. This document describes the configuration
and set up of the EVM board.
