STMicroelectronics L9374LF is a 1:4 N-Channel power switch/driver IC housed in a 36-PowerBSSOP (PowerSO-36) package with a bottom pad for enhanced thermal performance. This device is designed for power distribution and load driving applications. It features fixed current limiting, open load detection, over-temperature, and over-voltage fault protection, providing robust operational safety. The L9374LF supports an input voltage range of 5.2V to 20V and delivers up to 1.8A per output. Its outputs are configured as low-side N-Channel switches with typical Rds(On) values of 140mOhm and 250mOhm. Communication and control are managed via an SPI interface. This component is commonly utilized in automotive and industrial systems requiring reliable power management and protection for multiple loads. The L9374LF is supplied in a tube.
