STMicroelectronics L9349-LF is a high-side power switch featuring four N-channel outputs within a PowerSO-20 package. This device offers selectable output current capabilities of 3A or 5A per channel, with typical Rds On values of 200mOhm and 300mOhm respectively. The L9349-LF incorporates robust fault protection mechanisms including open load detection and over-temperature protection, along with a status flag for monitoring. Its input interface is a simple ON/OFF control, making it suitable for general-purpose switching applications. Designed for surface mounting, this component operates across a wide temperature range of -40°C to 150°C (TJ). It finds utility in automotive and industrial applications requiring reliable power distribution and load management.
