Overview
The IPS161HFTR from STMicroelectronics is a high-side power switch IC designed to drive capacitive, resistive, or inductive loads with one side connected to ground. This monolithic device operates within an 8 V to 60 V voltage range and features a low on-state resistance (Rds(on)) of 60 mΩ. It is packaged in a PowerSSO12 format, making it suitable for various industrial and automotive applications. The IPS161HFTR is known for its fast start-up propagation delay, non-dissipative short-circuit protection, and comprehensive diagnostic capabilities, including open load, overload, and thermal shutdown detection.
