L9904 ST Automotive Gate Driver | 20-SO | 4-Channel, 600mA

Product Overview

The L9904 is a monolithic quad low-side driver designed by STMicroelectronics for automotive and industrial applications. It integrates four independent low-side drivers with a common output clamp for inductive loads. Housed in a compact 20-SO package, it provides up to 600mA per channel and features over-temperature and short-circuit protection. The device operates from a 4.5V to 36V supply voltage, making it suitable for 12V and 24V systems.
