L9949 Datasheet - STMicroelectronics

DESCRIPTION
The L9949 is a microprocessor controlled power interface for automotive applications. It is realized in multipower BCD60III technology.

■ ONE FULL BRIDGE FOR 6A LOAD (ron = 150mΩ)
■ THREE HALF BRIDGES FOR 1.6A LOAD (ron = 800mΩ)
■ ONE HIGHSIDE DRIVER FOR 6A LOAD (ron = 100mΩ)
■ VERY LOW CURRENT CONSUMPTION IN STANDBY MODE (IS < 6µA, typ. Tj ≤ 85°C)
■ SERIAL PERIPHERAL INTERFACE (SPI) TO MICROCONTROLLER
■ ALL OUTPUTS SHORT CIRCUIT PROTECTED
■ CURRENT MONITOR OUTPUT FOR FULL BRIDGE AND HIGHSIDE DRIVER
■ ALL OUTPUTS OVER TEMPERATURE PROTECTED
■ OPEN LOAD DIAGNOSTIC FOR ALL OUTPUTS
■ OVERLOAD DIAGNOSTIC FOR ALL OUTPUTS

APPLICATIONS
■ FOR AUTOMOTIVE APPLICATIONS, E.G.
