Infineon TLE7242-2G: Dual-Channel High-Current Proportional Solenoid Driver

In the realm of automotive and industrial automation, precise control of proportional solenoids is critical for applications such as advanced valve control, hydraulic systems, and fuel injection. The Infineon TLE7242-2G stands out as a highly integrated, dual-channel solenoid driver IC engineered to meet these demanding requirements. Combining robust performance with diagnostic capabilities, this driver is designed to enhance system reliability and efficiency.

Key Features and Architecture

The TLE7242-2G is a dual-channel high-current proportional driver, capable of delivering up to 2.5A per channel. It operates from a supply voltage range of 5.5V to 28V, making it suitable for both 12V and 24V automotive systems. Each channel incorporates a pulse-width modulation (PWM) current controller with adjustable frequency and duty cycle, allowing for precise linear current control—essential for proportional solenoid actuation.

The device integrates protected MOSFET outputs with low RDS(on), ensuring minimal power dissipation and high efficiency. Its built-in diagnostics include over-current detection, over-temperature shutdown, and open-load detection, which contribute to enhanced system safety and longevity. Communication via a SPI interface enables real-time configuration and monitoring of parameters such as current setpoints and fault status.

Applications and Advantages

The TLE7242-2G is ideal for applications requiring accurate proportional control, such as transmission control units (TCUs), hydraulic valves, and exhaust gas recirculation (EGR) systems. Its ability to provide smooth and precise current regulation reduces mechanical stress on solenoids, improving response times and overall system performance. The dual-channel design also allows for compact PCB layouts, reducing both cost and space.
