BTN7930PAKSA1

Overview

The BTN7930PAKSA1 is a high-current half-bridge driver from Infineon's NOVALITHIC™ family, designed for automotive and industrial motor control applications. It integrates power MOSFETs in a single package to drive DC motors or ignition coils. The device features a compact SOIC-7 surface-mount package with an exposed thermal pad for efficient heat dissipation. It operates within a supply voltage range of 8 V to 18 V and supports peak output currents up to 42 A. Built-in protection mechanisms include overcurrent, overvoltage, undervoltage, and thermal shutdown to ensure robust system reliability under harsh operating conditions.

Feature Summary

• Integrates high-side and low-side power stages in a single compact package
• Includes comprehensive protection against overcurrent, overvoltage, undervoltage, and thermal faults
• Optimized for high-efficiency switching with low on-resistance power MOSFETs
• Designed for direct interface with standard microcontroller logic levels

Applications

• Automotive DC motor control systems
• Ignition coil drivers
• Industrial motion control actuators
• General-purpose high-current switching loads

Procurement Notes

Verify the complete orderable part number BTN7930PAKSA1 against official Infineon documentation to confirm package type and suffix specifications. Ensure compatibility with your system's voltage and current requirements before procurement. Check for any specific handling instructions related to the exposed thermal pad during assembly. Confirm that the component meets the necessary automotive or industrial qualification standards required for your application environment.

Selection Notes

Select this component when a compact, high-current half-bridge solution is required for driving inductive loads. Consider its integrated protection features for simplified design and enhanced reliability. Evaluate the thermal performance capabilities relative to your expected duty cycle and ambient temperature conditions. Compare it against other NOVALITHIC™ devices if different current ratings or pin configurations are needed for your specific board layout constraints.

Part Context

This part belongs to Infineon's NOVALITHIC™ series, which combines gate driver and power MOSFETs in a single package. This integration reduces component count, PCB area, and parasitic inductances compared to discrete solutions. The family is widely used in automotive electronics due to its robustness and efficiency. The BTN7930 variant specifically targets applications requiring moderate to high current switching capabilities in a small form factor.

Replacement Considerations

Consult Infineon's official cross-reference tools for verified substitutes. Ensure any replacement matches the SOIC-7 package, voltage rating, and current capability. Verify pinout compatibility to avoid redesigning the PCB. Check for equivalent protection features and thermal performance characteristics.
