Infineon BTS710336ESAXUMA1 High-Current PROFET™ Smart High-Side Switch: Powering Next-Generation Automotive and Industrial Applications

The Infineon BTS710336ESAXUMA1 represents a significant advancement in the realm of high-side power switches, integrating robust performance with intelligent protection features. As part of Infineon's renowned PROFET™ (Protected MOSFET) family, this device is engineered to handle high-current loads up to 35A, making it an ideal solution for demanding automotive and industrial systems, including body control modules, powertrain systems, and solenoid/valve control.

A key strength of the BTS710336ESAXUMA1 lies in its advanced diagnostic and protection capabilities. It offers comprehensive real-time feedback on operational status, including over-current detection, over-temperature shutdown, and load short-circuit protection. This ensures unparalleled system reliability by preventing catastrophic failures and enabling predictive maintenance. The device also features reverse battery protection, a critical requirement in automotive environments where electrical transients are common.

The integration of a charge pump allows for efficient control of the internal N-channel MOSFET using standard logic-level signals from a microcontroller, even at low battery voltages. This results in low quiescent current and minimal power dissipation, enhancing overall energy efficiency. Furthermore, its ESD robustness and AEC-Q100 qualification guarantee performance under harsh conditions, meeting stringent automotive industry standards.

Packaged in a DSO-14 housing, the component is optimized for space-constrained applications while providing effective thermal management. Its serial diagnostic interface (SPI) enables detailed system monitoring and fault logging, simplifying design-in and debugging processes for engineers.
