1 Introduction

The TPS3704Q1EVM is an evaluation module (EVM) for the TPS37044-Q1 voltage supervisor. This EVM can be used with any TPS3704x-Q1 device variant in DDF package. Test points are provided to give the user additional access, if needed, for oscilloscope or multi-meter measurements.

The TPS3704Q1EVM comes pre-populated with TPS37044A7OHDDFRQ1. This option is capable of monitoring four distinct input voltage rails and outputting an active low RESET signal on RESET1 and/or RESET2 depending on the state of the input voltages. If users need a different option, the existing device must be removed from the board and replaced. The EVM board is designed to support all possible options by changing jumper configurations.
