STMicroelectronics L9352B Intelligent Quad Low-Side Switch Datasheet
The L9352B is an integrated quad low-side power switch designed to drive inductive loads such as valves used in ABS systems. It features four channels where two are designed as conventional switches and two as switched current regulators with a range from 0 mA to 2.25 A. The device includes integrated free-wheeling and clamping Z-diodes, status push-pull stages, and output slope control.
