IPS2050HQ

Power Distribution Switches, Load Drivers Overview

The STMicroelectronics IPS2050HQ is a dual-channel high-side intelligent power switch designed for industrial applications. It integrates control logic and power stages on a single chip, featuring a low ON-resistance of 80 mΩ per channel. The device supports an operating voltage range from 10.5 V to 36 V and delivers a continuous output current of 0.7 A per channel. It includes comprehensive protection mechanisms such as overtemperature and overvoltage safeguards, alongside dedicated diagnostic signals for under-voltage lockout, short circuits, and ground disconnection. The component utilizes a QFN48L package measuring 8 x 6 x 0.9 mm.
