Infineon BTS724G: High-Current PROFET™ Smart High-Side Power Switch

In the realm of automotive and industrial electronics, efficient and robust power management is paramount. The Infineon BTS724G stands out as a premier solution, integrating four independent high-side power switches into a single compact package. As part of Infineon’s PROFET™ (PROtected FET) family, this device is engineered to deliver high-current switching with advanced protection features, making it ideal for demanding applications such as driving resistive, capacitive, and inductive loads.

One of the key strengths of the BTS724G is its ability to handle continuous current up to 28 A per channel, with a maximum operating voltage of 40 V. This high-current capability, combined with low standby current and low on-state resistance (RDS(on)), ensures minimal power dissipation and enhances overall system efficiency. Each channel is controlled via a separate input pin compatible with CMOS and TTL logic levels, allowing seamless interfacing with microcontrollers.

The device excels in providing comprehensive diagnostic and protection functions. It features overtemperature shutdown, overcurrent limitation, and load current feedback for each channel. Additionally, the BTS724G includes short-circuit protection and overvoltage clamp mechanisms, safeguarding both the switch and the connected loads from potential damage. The open-drain diagnostic output pin provides real-time status information, enabling proactive system monitoring and fault detection.

Housed in a PG-DSO-20-37 package, the BTS724G offers excellent thermal performance and mechanical durability. Its automotive-grade qualification ensures reliability under harsh conditions, including wide temperature ranges and voltage transients.
