BTS724GXUMA1: High-Current PROFET™ Smart High-Side Power Switch

In the realm of automotive and industrial electronics, managing high-current loads with precision, protection, and intelligence is a fundamental requirement. The BTS724GXUMA1, a member of Infineon’s PROFET™ (Protected FET) family, stands out as a robust and highly integrated quad-channel smart high-side power switch engineered to meet these demanding challenges. Combining four independent channels into a single package, this device delivers superior performance for driving resistive, capacitive, and inductive loads—such as lamps, valves, motors, and heaters—with exceptional reliability.

A key strength of the BTS724GXUMA1 lies in its high-current capability, with each channel capable of handling up to 4.5 A continuous current. Housed in a thermally enhanced PG-TSDSO-14 exposed pad package, the device ensures efficient heat dissipation, making it suitable for high-power applications in harsh environments. Its integrated protection features significantly enhance system durability. These include advanced diagnostic functions such as load current feedback, overtemperature shutdown, overvoltage protection (including load-dump survival), and short-circuit protection. Crucially, the switch provides open-load detection both in on-state and off-state, adding a vital layer of diagnostic capability for safety-critical systems.

The intelligence of this PROFET™ device is further highlighted by its multiplexed analog current sense feedback pin. This feature allows the microcontroller to monitor the load current of each channel sequentially, optimizing pin usage on the MCU and reducing overall system cost and complexity. Additionally, the low standby current and compatibility with 3.3 V and 5 V logic-level CMOS inputs make it ideal for modern electronic architectures, particularly in automotive body control modules, power distribution units, and industrial automation systems.

ICGOOODFIND: The BTS724GXUMA1 exemplifies the evolution of power switching, merging high-current handling, comprehensive embedded protection, and detailed diagnostic reporting into a compact form factor. It provides designers with a reliable, space-saving solution that enhances system functionality while ensuring operational safety and longevity.
