Single P-channel high-side switch for 8 V to 60 V industrial loads
The STMicroelectronics IPS160HTR is a single-output, high-side power switch built around a P-channel MOSFET. It switches loads from 8 V to 60 V, delivers up to 2.5 A continuously, and presents a typical on-resistance of 60 mOhm — low enough that conduction loss stays manageable even at full load in a 12 V or 24 V industrial bus system. The switch is self-contained: it requires no external Vcc supply rail (the gate drive is derived from the load voltage), and its On/Off interface accepts a non-inverting logic-level input. That makes it a drop-in replacement for a discrete P-channel FET plus gate driver, saving board area and BOM count.
2.5 A output with 60 mOhm Rds(on) — thermal headroom for continuous duty
At 2.5 A the conduction loss is I² × R = 0.375 W typical at 25°C junction. The PowerSSO-12 package (3.90 mm width, exposed pad) can sink that without forced airflow, but the 60 mOhm figure rises with temperature — expect roughly 1.5× at 125°C junction. Budget the copper area on the PCB pad accordingly. Built-in over-temperature protection and undervoltage lockout (UVLO) handle fault conditions. If the die exceeds the thermal threshold, the switch latches off until it cools — no external sense resistor or comparator needed. The UVLO prevents the gate drive from operating below the minimum load voltage, avoiding partial enhancement and excessive dissipation.
