L9822E(2013) Datasheet PDF - STMicroelectronics

Octal serial solenoid driver

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.
Status monitor function is available on all output lines.
