PROFET™ Smart High-Side Switch Evaluation Boards

Introduction

Infineon PROFET™ Smart High-Side Switch Evaluation Boards provide a practical platform for evaluating protected power-switching solutions in 48 V electrical systems. Built around selected PROFET smart high-side switch devices, these daughterboards help engineers assess switching behavior, diagnostic functions, protection features, and load-control performance before developing a custom design.

The available boards support output voltages up to 60 V and are intended for use with a compatible motherboard.

Part Description

The PROFET™ Smart High-Side Switch Evaluation Board family includes the following product variants:

• D-BTH6035-1EPL-4
• D-BTH6070-2EPV-4
• D-BTH6080-1EPL-4
• D-BTH6100-2EPA-4
• D-BTH6200-1ENA-4
• D-BTH6200-4ESA-4

Each board is a daughterboard designed to demonstrate an Infineon smart high-side switch in a controlled test environment. A high-side switch is installed between the positive supply rail and the load, enabling the system to connect or disconnect power while retaining a common ground connection.

PROFET devices combine power switching with integrated monitoring and protection capabilities. Depending on the selected device, features may include overload protection, short-circuit protection, overtemperature shutdown, current sensing, diagnostic feedback, and controlled switching behavior. These capabilities can simplify the design of robust 48 V load-control channels compared with using discrete switches, drivers, and protection circuitry.

Because these are evaluation daughterboards, they require an appropriate compatible motherboard to supply power, provide control signals, and access diagnostic interfaces.

Applications

Potential applications for these evaluation boards include:

• 48 V power distribution testing
• High-side load switching
• Automotive lighting control
• LED and lamp load management
• Motor and actuator power control
• Solenoid and valve switching
• Industrial load switching
• Electronic fuse evaluation
• Battery-powered equipment load management
• Diagnostic and fault-response validation
• Automation control panels
• Vehicle body-electronics development

Industries

These boards can support development and prototyping in several industries:

• Automotive and electric vehicles
• Commercial vehicles
• Agricultural machinery
• Construction and off-highway equipment
• Industrial automation
• Factory equipment manufacturing
• Robotics
• Material-handling systems
• Energy storage systems
• Smart infrastructure
• Building automation
• Transportation and mobility equipment

Usage Ideas

1. 48 V Lighting Controller
   Build a prototype controller for LED work lights or exterior vehicle lamps, using the board to switch the lighting load and evaluate protection behavior during wiring faults.

2. Protected Motor Power Channel
   Use the evaluation board to control power to a small 48 V DC motor, pump, or fan while testing startup current, overload response, and thermal shutdown performance.

3. Industrial Load Distribution Module
   Create a multi-channel concept for distributing 48 V power to valves, sensors, and actuators, using PROFET diagnostics to identify open-load or short-circuit conditions.

Conclusion

Infineon PROFET™ Smart High-Side Switch Evaluation Boards are useful development tools for designers working with protected 48 V power distribution and load-control systems. Their smart switching architecture helps engineers investigate load behavior, fault handling, diagnostics, and protection functions in automotive and industrial environments. When paired with a compatible motherboard, these daughterboards provide a convenient starting point for evaluating high-side switching solutions rated for output voltages up to 60 V.
