STMicroelectronics' Intelligent Power Switch Automatically Adjusts to Handle Inrush Current

STMicroelectronics' IPS1050LQ low-side switch IC provides flexible overcurrent protection, including a static mode with fixed, programmable current limit and a dynamic mode that safely handles high inrush current.

With a maximum rating of 65V, for the output stage, the IC can be used in equipment such as programmable logic controllers (PLCs), factory automation, and CNC machines. The IC has three pins for selecting the static or dynamic mode and setting the operating current limit, allowing eight permissible values. In static mode, the activation level and threshold can be set using external re
