Overview
The IPS161H is a monolithic high-side switch produced by STMicroelectronics. It is designed to drive capacitive, resistive, or inductive loads with one side connected to ground. This device is particularly suited for applications requiring high safety integrity levels (SIL) due to its comprehensive set of protective features and diagnostic capabilities. The IPS161H operates within an 8 V to 60 V voltage range and has a minimum output current limitation of 0.7 A. It features built-in overload and thermal shutdown protections, ensuring the device, the application, and the load are protected against electrical and thermal overstress.
