TPS7H3xx4EVM-CVAL Evaluation Modules

Introduction

Texas Instruments TPS7H3xx4EVM-CVAL evaluation modules are development platforms for assessing the TPS7H3xx4 family of radiation-hardened power-supply supervisor ICs. These modules help engineers evaluate voltage-monitoring, reset, watchdog, and power-good functions in demanding high-reliability power systems.

Part Description

The TPS7H3xx4EVM-CVAL evaluation modules are designed to support evaluation of four-channel power-supply supervisory devices in the TPS7H3xx4 family. They provide a practical board-level environment for testing how the supervisor responds to multiple monitored voltage rails.

Key supported functions include:

• Four-channel voltage monitoring
• Programmable voltage thresholds
• Adjustable timing behavior
• Reset output evaluation
• Power-good indication
• Watchdog functionality
• Multi-rail power sequencing and fault-response testing
• Evaluation of radiation-hardened supervisory solutions

These evaluation modules are particularly useful when validating system behavior during startup, shutdown, brownout, overvoltage, undervoltage, or watchdog timeout events. Engineers can use the board to characterize supervisory settings before integrating the corresponding IC into a final design.

Applications

Potential applications for the TPS7H3xx4EVM-CVAL include:

• Multi-rail power-supply monitoring
• Power-on reset validation
• Power sequencing verification
• Undervoltage and overvoltage fault detection
• Processor watchdog testing
• Power-good signal generation
• Fault-management circuit development
• High-reliability embedded power systems
• Radiation-tolerant electronic system prototyping
• Remote power-control and status-monitoring designs

Industries

Possible industries for these evaluation modules include:

• Aerospace
• Space and satellite systems
• Defense electronics
• Avionics
• Scientific instrumentation
• Nuclear and radiation-exposed systems
• Industrial automation
• Telecommunications infrastructure
• High-reliability computing
• Research and development laboratories

Usage Ideas

1. Satellite Power-Rail Monitor
   Build a prototype that monitors core, memory, I/O, and communication power rails, issuing a reset or fault signal whenever one rail falls outside its allowed operating range.

2. Radiation-Hardened Controller Reset System
   Evaluate reset timing and watchdog behavior for a processor-based control board intended for aerospace, defense, or other radiation-prone environments.

3. Multi-Voltage Power Sequencing Test Bench
   Connect programmable bench supplies to the four monitored inputs and simulate startup, brownout, and shutdown events to verify power-good and reset responses.

Conclusion

The Texas Instruments TPS7H3xx4EVM-CVAL evaluation modules provide a convenient platform for exploring the TPS7H3xx4 family of radiation-hardened power-supply supervisors. With support for four-channel monitoring, configurable thresholds and timing, reset control, power-good signaling, and watchdog functions, they are well suited for developing dependable multi-rail power-management systems used in high-reliability applications.
