The IPS1050LQ from STMicroelectronics is a Single-Channel Low-Side Solid-State Switch IC designed for industrial applications such as numerical control machines, industrial PC peripheral I/O, and programmable logic control systems. It requires a supply voltage of 5.8-10 V and an input current of 1-1.4 mA. This IC can drive resistive, capacitive, or inductive loads and integrates smart overload protection with configurable inrush and steady-state current limitation levels. It supports inrush currents up to 25 A and a very low on-state resistance of less than 50 milli-ohms.

This power switch features fast demagnetization of inductive loads, junction over-temperature protection, and an over-temperature diagnostic pin (OVT) for fault monitoring. It complies with IEC 61000-4-2, IEC 61000-4-4, and IEC 61000-4-5 standards, ensuring robust EMC performance. This power switch is available in a surface-mount package that measures 6 x 6 mm.
