TPS4141Q1EVM Hardware Evaluation Module (EVM)

Introduction

The Texas Instruments TPS4141Q1EVM is a hardware evaluation module for assessing the TPS4141-Q1 power-management IC. It provides a practical development platform for exploring configurable voltage monitoring and amplifier-gain settings, with board-level access to key signals and supplies.

The module is intended as a specialized power-management development tool rather than an end-product power supply. Its combination of configurable monitoring modes, an onboard 5 V LDO regulator, and a 2.05 V reference supports evaluation of the TPS4141-Q1 in voltage-sensing and ADC-connected designs.

What it does

The TPS4141Q1EVM enables evaluation of the TPS4141-Q1 with configurable bidirectional or unidirectional voltage monitoring. Its amplifier gain can be configured to optimize the signal presented to an ADC, allowing developers to examine how gain selection and monitoring direction affect an intended measurement arrangement.

The board includes:

• An onboard 5 V LDO regulator
• A 2.05 V voltage reference
• Test points for every pin and voltage supply
• Terminal blocks for high-voltage wired connections
• Jumpers and accessible connections for configuration and test

It can operate as a standalone evaluation board or alongside an external microcontroller. In the latter arrangement, the microcontroller can drive enable and configuration signals for the evaluation setup.

Applications

Potential uses for the TPS4141Q1EVM include:

• Evaluating TPS4141-Q1 voltage-monitoring configurations
• Developing bidirectional or unidirectional voltage-sensing circuits
• Assessing amplifier-gain settings before connecting a monitored signal to an ADC
• Prototyping microcontroller-controlled enable and configuration interfaces
• Characterizing accessible power-management and sensing signals using the board test points

Design considerations

The EVM provides terminal blocks for high-voltage wired connections, so system-level evaluation should account for the required external wiring arrangement. Test points are available for every IC pin and voltage supply, which can simplify probing and measurement during development.

For ADC-connected designs, the configurable amplifier gain is a central integration consideration. The board’s selectable bidirectional and unidirectional monitoring modes also allow the measurement approach to be matched to the intended signal direction. The onboard 5 V LDO and 2.05 V reference should be considered when planning the surrounding evaluation circuitry and measurement setup.

When using external control, the board supports an external microcontroller for enable and configuration signals, providing a path to evaluate firmware-controlled operating conditions.
