Overview
The IPS160HTR, produced by STMicroelectronics, is a high-side switch integrated circuit designed to drive capacitive, resistive, or inductive loads. This monolithic device operates within an 8 V to 60 V voltage range and features a low on-state resistance (Rds(on)) of 60 mΩ. It is particularly suited for applications requiring robust protection and diagnostic capabilities, such as programmable logic control, industrial PC peripherals, numerical control machines, and domotics.
