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.
