DESCRIPTION
The L9822E is an octal low side solenoid driver realized in Multipower-BCD technology particularly suited for driving lamps, relays and solenoids in automotive environment. The DMOS outputs L9822E has a very low power consumption.
Data is transmitted serially to the device using the Serial Peripheral Interface (SPI) protocol.
The L9822E features the outputs status monitoring function.
