Description

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.

■ Four low-side output driver with protection diagnostics designed as a conventional switch

– 2 channels with 5 A output current capability and rON = 0.2 Ω typ.

– 2 channels with 3 A output current capability and rON = 0.3 Ω typ.

■ Integrated 60 V Zener diodes output clamping structure

■ Output slope control

■ Short circuit protection

■ Open load detection in ON and OFF condition

■ Load bypass detection

■ Overload disable

■ Signal and power ground loss shutdown

■ Selective overtemperature shutdown

■ Electrostatic discharge (ESD) protection
