The L6374FP is a Quad, fixed-input Current Limiting, Low-Side, Automotive-grade, High-Speed, DMOS-Driver with integrated current sensing, manufactured by STMicroelectronics in a SOIC-20 package. This line driver is typically used in automotive environments, and features a 100mA continuous output current (300mA peak) and under-voltage lockout. It has a power supply voltage range of 10.8 to 35V, and features built-in thermal shutdown protection with a fast response time. It is highly efficient, allowing users to reduce current dissipation. This device is ideal for low-side switching applications operating in the medium to high power range, such as headlights and lamps.
