Product Overview
The BTS724G is a quad-channel smart high-side power switch from Infineon Technologies (Classic PROFET 24V family), integrating four independent N-channel power MOSFETs with comprehensive protection and diagnostic circuitry in a single PG-DSO-20 package. Each channel provides 3.3A nominal load current with 70mOhm typical on-resistance at 25°C. It features overtemperature, overcurrent, and ESD protection, CMOS-compatible inputs, and digital status feedback for automotive and industrial applications.
