STMicroelectronics L9822E Octal Serial Solenoid Driver Datasheet
The L9822E is an octal low-side solenoid driver realized in Multipower BCD technology, specifically suited for driving lamps, relays, and solenoids in automotive environments. It features eight DMOS outputs capable of handling a nominal load current of 500mA with internal clamping up to 36V.
Data is transmitted serially using the Serial Peripheral Interface (SPI) protocol, allowing an external microcontroller to control all output lines individually. The device includes status monitor functions on all output lines for diagnostic purposes and offers chip enable select functionality.
