TPS272C45 Evaluation Module
The TPS272C45EVM is a hardware evaluation module (EVM) used to enable hardware engineers to evaluate
the full performance and functionality of the TPS272C45 industrial high side switch. The TPS272C45EVM
contains everything needed to test and assess the TPS272C45 before designing it 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 headers. A wide range of application features such as current sensing,
multiplexed current limiting, and transient suppression are enabled and visible through use of this evaluation
module.

  • Page 1: Table Of Contents

    TPS272C45 industrial high side switch. The TPS272C45EVM contains everything needed to test and assess the TPS272C45 before designing it 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 headers.
  • Page 2: Introduction

    TPS272C45 industrial high side switch. This evaluation board provides a seamless way to connect a set of power supplies to the inputs of the TPS272C45, 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 TPS272C45 and easily assert and deassert logic signals by the use of a set of external hardware jumpers.
  • Page 3: Compatibility Across Silicon Versions

    The A, C and D version of the device includes the ability to power the digital logic of the TPS272C45 from an external Vdd pin. While the Vdd input pin exists on the A version of the TPS272C45 it does not exist in the B versions.
  • Page 4: Boosterpack Operation

    Additionally the header labeled J18 can be used to configure how the FAULT pin is pulled up. This pin is an open drain output used to report faults on the TPS272C45 such as overcurrent or open load.
