Description

General part information

L9349-LF Series

The L9349 is a monolithic IC designed to drive inductive loads in low side configurations like hydraulic valves used in ABS systems.

Particular care has been taken to protect the device against failures, to avoid electromagnetic interferences and to offer extensive real time diagnostics.

The internal pull down current source at the ENable and INput pins assures, that the device is switched off, in case of open input conditions.
