TPS3700EVM-202 High voltage (18V) window voltage
This user's guide describes the operational use of the TPS3700EVM-202 Evaluation Module (EVM) as a
reference design for engineering demonstration and evaluation of the TPS3700EVM high voltage, over
and under voltage supervisory circuit. Included in this user's guide are setup instructions, a schematic
diagram, PCB layout drawings, and a bill of materials for the EVM.

Introduction
TI's TPS3700EVM-202 EVM helps design engineers evaluate the operation and performance of the
TPS3700 IC for possible use in their own circuit application. This particular EVM configuration contains an
over and under voltage supervisory circuit with a wide supply range, independent open drain outputs, very
low quiescent current, and high accuracy in a 1.5 mm × 1.5 mm DSE package. This document describes
the configuration and set up of the TPS3700EVM-202 EVM board.
